EAS 2019 was held in conjunction with the Experimental Aviation Association’s annual AirVenture in Oshkosh, July 22-28 (see eVTOL News from AirVenture).

Two dozen of the world’s leading electric aircraft developers and technology experts spoke at EAS 2019, all of which are available for free viewing in 26 videos on the VFS YouTube Channel. Don’t have time to watch all the videos? We’ve summarized the key points for each speaker, below, under the link to each video.

EAS 2019 #1 – Yolanka Wulff & Mike Hirschberg – Introduction & The Electric VTOL Revolution

INTRODUCTION & STATE OF THE INDUSTRY SESSION
Yolanka Wulff, Executive Director, CAFE Foundation
Mike Hirschberg, Executive Director, Vertical Flight Society

Yolanka Wulff, Executive Director of the CAFE Foundation welcomed speakers and guests to the 13th Annual Electric Aircraft Symposium (EAS) in Oshkosh, Wisconsin, on July 20-21, 2019.

VFS Executive Director Mike Hirschberg spoke about “The VTOL Revolution” and what the VFS has been doing to advance the eVTOL industry and technology, and become the de facto industry eVTOL society.

As of July 2019, more than 50 VFS corporate members are now engaged in eVTOL aircraft development and the VFS added the 191st eVTOL aircraft program to its authoritative World eVTOL Aircraft Directory. The Directory provides comprehensive information on 67 Vectored Thrust, 26 Lift + Cruise, 46 Wingless (Multicopters), 38 Hover Bikes/Flying Devices, and 14 eHelos & eGyros aircraft.

Hirschberg explained why eVTOL development is surging today and how the challenges are similar to those the pioneers of the US helicopter industry faced in 1943 when the VFS (then known as the American Helicopter Society) was established to advance the technology and acceptance of the helicopter and create a robust vertical flight technical community.

EAS 2019 #2 – Ryan Naru – UberAir eVTOL Concepts

STATE OF THE INDUSTRY SESSION
Ryan Naru, Vehicle Standards Engineer, Uber Elevate

Naru began his presentation by outlining what Uber is looking for in an eVTOL aircraft for its Elevate aerial ride share network. The Uber Elevate white paper was released in October 2016 and signaled Uber’s intent to be a “motivator in this industry” which was followed by the first Uber Elevate conference in April 2017. In 2018, Uber began using its “flux” data tool to understand how commuter traffic flows through cities and released its eVTOL vehicle requirements to partner OEMs. In July 2019, Uber Copter started multi-modal helicopter service linking Manhattan with JFK Airport.

The first UberAir eVTOL demonstration flights are scheduled to begin in 2020 with initial certified operations expected in 2023. The company plans to expand and optimize its network by 2026, and then increase scale as second generation eVTOL aircraft enter service by 2028.

Uber combined its “flux” data tool with a demand model to study the trade-off between how people value their time and their money. These tools are being used to help identify the best locations for the urban Skyports that will be the multi-modal terminals for Elevate’s eVTOL service.

Naru says Uber’s system requirements for an eVTOL aircraft include a cruise speed of 150 mph, a payload of a pilot plus four passengers, 60-mile range, 15 dB improvement in noise over helicopters, electric propulsion, and a utilization rate of 2,000 flight hours per year.

Uber has developed a system for scoring various eVTOL aircraft design configurations that includes complexity, part criticality and high performance (Lift/Drag x cruise speed). They are measuring the total number of parts and also their criticality to the design. And the performance measurement is used to calculate how many missions the eVTOL aircraft can accomplish in a “three-hour sprint.”

As a result, most of the eVTOL aircraft being considered for UberAir are Lift + Thrust and vectored thrust concepts.

Naru explained that for Uber, “Redundancy + Reliability – Criticality = Safety.”

Thus, the ideal Uber vehicle has high speed, sufficient capacity and good range in order to satisfy the demand they see in the cities they are targeting for eVTOL service. They also want the aircraft to be “green,” quiet and safe.

This means Uber is not considering hybrid-electric aircraft at this time. And all of Uber’s six eVTOL partners are developing aircraft that also have a wing for efficient cruise flight.

EAS 2019 #3 – Willi Tacke – Electrifying Aviation Factors for Making Disruptive Change Happen

STATE OF THE INDUSTRY SESSION
Willi Tacke, Founder and Organizer of the e-flight-expo at AERO; CEO of Flying Pages

Willi Tacke highlighted the rapid growth of “e-flight” including recent announcements at the AERO aviation trade show in Germany and the Paris Air Show. For example, at Paris Airbus displayed eVTOL aircraft beside their large commercial aircraft; Rolls Royce announced its acquisition of Siemen’s electric aviation unit; Eviation revealed its Alice electric aircraft and an order from Cape Air; and Safran and Daher announced a new electric aircraft partnership.

EAS 2019 #5 – Gilles Rosenberger – Some Economical Comments on e-Aviation

EMERGING TECHNOLOGIES SESSION
Gilles Rosenberger, CEO, Faraday Aerospace

Gilles Rosenberger, offered “Some Economical Comments of e-Aviation”, primarily focused on understanding the variables that determine the direct operating cost (DOC) of electric-powered aircraft.

Rosenberger noted that the aviation industry has limited experience evaluating and comparing the DOCs of electric aircraft, but there is a lot of real-life experience in the automotive industry.

He said the most important factors to consider when calculating DOCs are battery end of life (EOL), calendar life and cycle life. Automobile experts consider EOL at 30% capacity loss, calendar life of 8-10 years and cycle life of 1,000 – 1,500 cycles However, when it comes to aviation, Rosenberger says very limited information is available since only one electric aircraft — the Pipistrel Alpha Electro — is in production today. He noted that a replacement battery pack for this aircraft costs €26,000 (US$29,300) to replace.

While the price of lithium ion battery packs ($/kWh) for automobiles continues to fall, Rosenberger expects aircraft-certified battery packs will cost at least three to four times more because of low volume demand and high certification requirements.

Rosenberger says a key parameter for battery replacement is the charge/discharge profile cycle, yet the industry has very little real-life information outside the flight training sector where a one-hour lesson would equal one cycle.

Uber is driving a lot of interest in eVTOL aircraft, but Rosenberger notes that Uber has been presenting different discharge profiles for the Urban Air Mobility mission.

“At Faraday, we anticipate two to three ‘equivalent’ cycles per working day. For 365-day-a-year air taxi operation, [this equals] 730 to 1095 cycles/year … and a 1,500-cycle battery replacement frequency of 24 months to 16 months.”

EAS 2019 #6 – David Ullman – eSTOL Potential for Urban Air Mobility

EMERGING TECHNOLOGIES SESSION
David G. Ullman, Principal, IDEAL eSTOL

Oregon State University Emeritus Professor Dr. David G. Ullman spoke about the potential of electric STOL (short takeoff and landing) aircraft for Urban Air Mobility.

“The goal here is to see if eSTOL can rival VTOL and identify what is unique and its potential,” said Ullman, who explained that there are three standard ways to shorten take-off distance of an aircraft:

  • Lower the wing loading (W/A) – low weight big wing. Cruise penalty.
  • Raise the thrust to weight ratio (T/W)
  • Raise the take-off lift coefficient

Ullman’s recent research has focused on using distributed electric propulsion (DEP) to create propulsion-airframe interaction (PAI) where air moved by the propulsor gains aerodynamic advantages as it passes over the airplane’s wings, fuselage and other surfaces.

One STOL aircraft configuration that Ullman finds quite intriguing was Willard Custer’s channel wing. Other aircraft like NASA’s QSRA (Quiet STOL Research Aircraft, based on a de Havilland Canada DHC-5 Buffalo) and Boeing YC-14 used upper surface blowing (USB) to achieve high lift coefficients.

Ullman is currently testing a number of different DEP configurations in a homemade wind tunnel and on his self-designed single-engine JabirWatt home-built aircraft that has been modified with four 120-mm electric ducted fans mounted to the wings for USB.

Ullman’s key takeaways:

  • “eSTOL can be designed to give very short take-off distances!”
  • “VTOLs need 2-5 times the power to take-off!”
  • “VTOL has nearly half the range of eSTOL.”

He believes that eSTOL aircraft could easily operate out of “pocket airports” built on one hectare (2.5 acres) of land featuring 420 ft long runways.

EAS 2019 #7 – Bruno Mombrinie – Metro Hope: The eSTOL Solution for Urban Air Mobility

EMERGING TECHNOLOGIES SESSION
Bruno Mombrinie, Founder & CEO, Metro Hop

Bruno Mombrinie, a CAFE Foundation board member, gave a presentation on the Metro Hop concept, an eSTOL aircraft design for urban air mobility. Metro Hop features two electric propellers and motorized landing gear legs that are articulated to help the aircraft takeoff in short distances and land smoothly on 200-foot long runways.

Mombrinie believes there is a large emerging market for piloted aircraft that can carry packages between warehouses as same day delivery becomes the norm.

Long term, Mombrinie believes Metro Hop will be used to carry passengers between eSTOL skyports. He explained that that departure/arrival rate (DAR) multiplied by the turnaround transit time (TTT) will determine the Skyport Station Size (S3), which is a measure of the number of aircraft and passengers a facility can handle at one time.

Mombrinie says that cruise speed is an important element for high-utilization UAM operations.

“The size of an Urban Air Mobility fleet is determined by the demand during peak periods. It may not matter much to the average passenger if they get there in about 10 minutes versus about 15 minutes. But to the operator that means about 50% more planes are needed in the fleet. The faster the planes, the fewer planes are needed,” says Mombrinie.

EAS 2019 #8 – Kenneth Swartz – Market Opportunities for Emerging Technologies

EMERGING TECHNOLOGIES SESSION
Kenneth I. Swartz, President, Aeromedia Communications; Board Member, Vertical Flight Society

With a long professional career in the regional airline and commercial helicopter industry, and as an aerospace journalist, Swartz spoke on “Market Opportunities for Emerging Technologies.”

His presentation reviewed the historical development of helicopter airlines and commuter/regional airlines, identified market opportunities for electric-powered conventional and VTOL aircraft, and described how aircraft manufacturers traditionally forecast commercial aircraft demand.

Helicopter airlines once carried thousands of passengers a month in the greater Los Angeles, San Francisco, Chicago and New York areas, Europe and elsewhere. Today, only a handful of scheduled helicopter airlines exist and most are located in regions where geographic barriers (e.g. oceans, islands, mountains, narrow roads) make competing transportation modes (e.g. marine ferry, road or train or airport) very time consuming. The development of new eVTOL will revive urban VTOL flights.

The history of commuter and regional airline industry also offers important lessons for the electric aircraft industry.

The de Havilland Aircraft of Canada company was one of the leading promoters of short-haul air transport utilizing its STOL aircraft. With the development of the DHC-6 Twin Otter and Dash 7, the company promoted the STOLport concept.

The combination of STOL aircraft and custom infrastructure was adopted in many countries. Norway developed a network of STOLports serving small coastal communities, as did Greenland and other countries. The most successful STOLport examples are Billy Bishop City Centre Airport in Toronto and London City Airport in the UK, which was initially restricted to STOL Dash 7s.

The most enduring short haul commuter airline routes can be found linking communities separated by geographic barriers such as water and mountains. Many of the airlines flying these routes have been targeted by electric aircraft makers.

For example, Harbour Air of British Columbia announced plans to re-engine its seaplane fleet with magniX electric motors, Cape Air of Massachusetts placed an order for the Eviation Alice, and Ampaire announced it will demonstrate its Cessna 337 EEL hybrid aircraft on routes flown by Mokulele Airlines of Hawaii and Vieques Air Link in Puerto Rico.

Since 2000, hundreds of short haul routes have been abandoned by large regional airlines as a result of airline consolidation, the retirement of smaller aircraft, rising operating costs, pilot shortages and the “hassle factor” (e.g. lengthy airport security screenings).

Electric commuter aircraft with low seat mile costs will help resurrect many of these short haul routes. Elsewhere, the government of Norway recently announced that all short haul flights under 90 minutes must be electric-powered by 2040!

EAS 2019 #10 – Todd Hodges – History of VTOL Design – Tilt Wings & Tilt Rotors

DAY 2 OPENING PRESENTATION
Todd Hodges, Retired Engineer, NASA Langley Research Center

Todd Hodges believes that it’s important for today’s electric vertical takeoff and landing (VTOL) aircraft designers to understand VTOL history, so they can begin where others left off, rather than redo the mistakes of the past.

The benefits include reducing the cost of development, shortening the development cycle and avoiding accidents that have happened before.

Hodges believes that “conventional takeoff and landing (CTOL) design is mostly a well-known science” whereas “VTOL design is still somewhat of a black art.”

Hodges began his presentation with the VTOL “Wheel of Misfortune,” originally created by McDonnell Aircraft in the 1960s and updated by the Vertical Flight Society in the 1990s. He then narrowed his focus to the history of tilt wing and tilt rotor aircraft developed over the past 75 years, which all use the same propulsion system for hover and forward flight.

Hodges says that aircraft “configuration selection is dependent on mission requirements – Range, Payload, Hover Time, Speed, Endurance, etc.”

“If you have to go fast, you will get pushed into the higher disk loadings. If your mission requires an extensive amount of hovering, you will end up at lower disk loadings. The balance between hover requirements and speed requirements for the mission will usually play a substantial role in configuration choice.”

Hodges then explained the positive and negative characteristics of tilt wing and tilt rotor aircraft.

After highlighting several aircraft examples from the past, Hodges concluded by stating that “new technologies like distributed electric propulsion (DEP) are appearing that will blow open the design space for new more efficient VTOL aircraft.”

EAS 2019 #11 – Earl Lawrence – FAA Certification of Electric Powered Aircraft

STANDARDS & CERTIFICATION SESSION
Earl Lawrence, Executive Director Aircraft Certification Service, FAA

Lawrence said that if you are developing new electric powered aircraft and plan to carry passengers on them, “then the FAA is your partner.”

He says that despite some negative perceptions, the FAA is actually very experienced at certifying new technology, and cited as an example the Boeing 787 “which is an all-composite electric aircraft … with turbine engines.”

When it comes to certification, “everything is about safety, especially for new innovations,” says Lawrence, adding that the nature of the aircraft operations will effect what safety issues the FAA has to look at to ensure the risks are mitigated.

He says that one of the new challenges is that companies are coming to the FAA today wanting to change how operations are conducted (e.g. licensing, airspace use and automation), which represent changes to a system overseen by the FAA’s separate certification, flight standards and air traffic management teams.

To this end, “the FAA is committed to working with companies as one group… early and often.”

EAS 2019 #12 – Gregory Bowles – FAA Type Certification of eVTOL

STANDARDS & CERTIFICATION SESSION
Gregory Bowles, Head of Government Affairs, Joby Aviation

Greg Bowles, head of government relations for Joby Aviation said the company is developing a 175 kt eVTOL aircraft that will be ten times faster than ground transportation for an urban air mobility (UAM) mission.

The Joby eVTOL is now in the FAA certification process and the company has recruited aircraft certification experts with 142+ combined years of experience certifying 23+ clean sheet aircraft to support its own efforts.

Bowles said that eVTOL aircraft developers have two major challenges – to perfect the technology and certify very safe aircraft in a regulatory environment that has matured over the past 50 to 60 years.

He said that several eVTOL companies are using FAR 23 as the basis for FAA certification and explained how regulators are adding additional requirements to address the unique aspects of the aircraft that differ from a traditional light aircraft.

EAS 2019 #13 – Tom Gunnarson – Unmanned Air Mobility: A New Paradigm

STANDARDS & CERTIFICATION SESSION
Tom Gunnarson, Cora Lead of Regulatory Affairs, Kitty Hawk

Tom Gunnarson, Lead of Regulatory Affairs for the Cora program at Kitty Hawk spoke at the CAFE Electric Aircraft Symposium about autonomous air mobility. He said that the unmanned sector of aviation includes a wide range of aircraft sizes, capabilities and missions. This includes different levels of control and communication, including human control using direct sensing and verbal communication (RPAS); self-flying semi-autonomous, monitored; and self-flying autonomous, monitored modes.

The biggest challenges today for the emerging eVTOL industry are: aircraft approval (new technology and hybrid aircraft category); infrastructure; and airspace integration.

Gunnarson also discussed what Self-Flying, Automation and Autonomous mean in the context of unmanned air mobility.

Many of the regulatory barriers to autonomy in aviation are now being addressed through the work of the ASTM AC377 task team while the means of compliance for eVTOL UAM aircraft is being addressed by the ASTM AC433 task team.

EAS 2019 #14 – Mark DeAngelo – Recent and Future Standards Developments for Electric Aircraft

STANDARDS & CERTIFICATION SESSION
Dr. Mark DeAngelo, Staff Leader, SAE International Electric Aircraft Steering Group (EASG)

Mark DeAngelo spoke on “Recent and Future Standards Developments for Electric Aircraft.”

SAE standards are routinely referenced by certification agencies like the FAA, EASA and Transport Canada.

Today, the SAE International Electric Aircraft Steering Group (EASG) strategically identifies, landscapes, and coordinates the various standardization activities necessary to support full-electric and more-electric aircraft applications at the top-level system, subsystem, and component levels with a wide range of work in progress.

EAS 2019 #16 – Peter Shannon – Thinking about Autonomy in Terms of Safety Assurance

SAFETY & OPERATIONS SESSION
Peter Shannon, Investor, Radius Capital

Peter Shannon’s presentation focused on “Implementing Autonomy in Terms of Safety Assurance.”

Shannon says that today, “We assure the safety of automated systems through verification and validation and, in some cases, certification.”

“As our technology for assuring safety improves, the pattern of replacing human functions with automation will repeat throughout aircraft as well as the overall airspace system.”

Shannon’s presentation offers an excellent illustration of how “evolving automation moves pilot out of inner control loops” … and how the “same process displaces humans from inner control loops across the airspace system.”

EAS 2019 #17 – Jim Murphy – NASA Advance Air Mobility, Urban Air Mobility and Grand Challenge

SAFETY & OPERATIONS SESSION
Jim Murphy, UAM Grand Challenge Technical Lead, NASA

Jim Murphy spoke on “NASA Advanced Air Mobility (AAM), Urban Air Mobility (UAM) and Grand Challenge.”

NASA is considering Urban Air Mobility cases where an aircraft is used in an urban area to transport people and cargo over ground traffic so passengers and goods can move more efficiently. In addition, the agency is also looking at the interurban air mobility covering longer distances.

NASA’s Urban Air Mobility (UAM) vision is to “Revolutionize mobility around metropolitan areas by enabling a safe, efficient, convenient, affordable, and accessible air transportation system for passengers and cargo.”

UAM framework includes:
Vehicle Barriers
– Vehicle Development & Production
– Individual Vehicle Management & Operations

Airspace Barriers
– Airspace System Design & Implementation
– Airspace & Fleet Operations Management

Community Barriers
– Community Integration

For the UAM Grand Challenge, NASA has defined six different UAM Maturity Levels (UML) across three states (initial, intermediate and mature) when it comes the operational system capability of vehicles, airspace and the community. (This is distinct from technological readiness levels, TRLs.)

The initial state might include VFR operations in rather simple scenarios with low levels of automation, whereas the mature UML 6 would see “Ubiquitous UAM Operations with System-Wide Automated Optimization.”

One of the key things NASA wants to understand as a research organization is the interoperability of a vehicle with the operating system that matches an operator’s use case. This will help NASA determine what is required from the government to support the expansion of future UAM activities

One thing that is unclear, says Murphy, is whether one system can support different concepts of operation for sets of passenger and cargo vehicles in the same air space.

NASA and the FAA have been working together at a high level to develop a concept of operations.

The goal of NASA’s initial UAM Grand Challenge is to “support requirements and system development for scalable, commercial UAM through integrated demonstrations of realistic operational scenarios.”

NASA’s objectives include:
1. Accelerate Certification and Approval
2. Develop Flight Procedure Guidelines
3. Evaluate the CNS Trade-Space
4. Demonstrate an Airspace Operations Management Architecture
5. Characterize Community Concerns

EAS 2019 #18 – Rex Alexander – Aircraft Performance and the Impact on Infrastructure

SAFETY & OPERATIONS SESSION
Rex Alexander, President, Five-Alpha LLC

Alexander said that almost 40 years flying helicopters, he found himself in the helicopter infrastructure consulting business because, “there came a point in time when I wondered why architects and engineers were trying to kill me very day.”

His company started doing a lot of education on heliport infrastructure, which should be thought of as a three dimensional quantity where airspace is attached to it and it is significantly affected by its environment.

Alexander says that how you design heliport infrastructure will have a huge impact on aircraft safety and performance, “and you should design ‘forgiveness’ into the design.”

Heliports are usually optimized for a “design aircraft” which for a helicopter is based on maximum rotor diameter and maximum overall length. The challenge today is what is going to be the “design aircraft” when you are building a facility for an eVTOL aircraft, since there are more than 175 prototype aircraft in development that have different configurations, with most having multiple rotors and many having a width that is greater than the length.

The FAA also wants to have performance data similar to what they have based their current infrastructure standards on, but this is a challenge because very little data has been released by the eVTOL community.

To move things along, the FAA issued an RFI earlier this year to get performance data from OEMs.

Alexander expects eVTOL aircraft to be operated from airports, heliports and vertiports, although the definition of a Vertiport still needs to be refined.

He also emphasizes that heliports located at ground level and on rooftops are NOT the same.

The key performance criteria in the helicopter world includes:
– Pilot Workload
– Aircraft Handling & Controllability
– Aircraft Performance Margins
– Passenger Ride Quality

One of the variables that helicopter pilots can play with who planning a mission is the weight and balance of the aircraft by adjusting the amount of fuel you put into an aircraft. With an eVTOL aircraft, Alexander says the battery volume & weight do not change in flight. “Hence, weight & balance are constant.”

He says this represents a major change to the way pilots will plan a flight, because they cannot manipulate aircraft weight (and performance) by adjusting fuel with an electric powered aircraft, since you can’t offload battery weight.

This means that for an eVTOL aircraft you have to be much more cognizant of the performance limitations of the aircraft than for a helicopter.

Environmental factors are also very important in heliport design, including wind (crosswind, tailwind) and turbulence (updraft, downdraft).

The power margin of a VTOL aircraft can be used to control, compensate or overcome environmental factors.

One advantage of electric VTOL aircraft is the availability of instant power compared to a turbine-powered aircraft.

Alexander says that ideal rooftop helipads have a large gap between the roof and the pad to allow turbulent air to flow over the roof below the helipad. Parking garages also make attractive heliports because air can flow through the structure.

Yolanka Wulff, co-founder, Community Air Mobility Initiative (CAMI)
www.communityairmobility.org

Wulff spoke briefly on the new non-profit association that she has founded with Anna M. Dietrich. CAMI was created for the purpose of “supporting the responsible integration of the third dimension into our daily transportation needs through education, advocacy, and community engagement.”

As technology and the Civil Aviation Authority-level regulatory landscape develops, the need for local advocacy and community and public education in support of urban air mobility (UAM) is becoming more acute. While other organizations provide federal-level advocacy, the success of the industry will hinge on air mobility being embraced by local communities, cities, states, and the general public. CAMI is the link to the local level, providing education and resources to the public, decision makers, and the media. We are here to help people and communities take to the skies.

Member organizations support the widespread adoption of personal aviation as a solution to the transportation challenges faced by individuals and communities. While Members need not be aircraft manufacturers or operators, each Member must prioritize safety, bring credibility to the consortium, and have a demonstrated desire to be a good neighbor within their community. Membership is tiered to allow levels of support and influence that are accessible to a variety of organizations.

EAS 2019 #21 – Rob Bulaga – GoFly Prize & FlyKart 2

ELECTRIC AIRCRAFT SESSION
Rob Bulaga, President, Trek Aerospace

Rob Bulaga has spent the past 20 years building ducted propellers for the aerospace industry, including his own company, and built his first electric powered drone in 2005.

Many of the projects Trek supported never advanced, so a few years ago Trek decided to design a small fun aircraft that would showcase its technology. A flying car was a little too ambitious so Bulaga decided to build a flying go-cart, which is how the FlyKart 1 built, in 2016, came into being.

Bulaga says the goal of FlyKart 1 was to build something that could fit into a one-car garage, be built as a kit for under $20,000, and assembled in a weekend. It is six and half feet in diameter and weights 225 lb, and can fly a 175 lb. person for about 20 minutes. The actual prototype cost less than $16,000 in parts and took less than a month to assemble.

“When the GoFly Prize contest came out, their requirements were so close to what we were already doing that we knew we had to compete in GoFly.”

Bulaga outlined the goal of GoFly (www.GoFlyPrize.com) and the prizes associated with Phase 1, Phase 2 and Phase 3 of the competition as well as how the scoring takes place.

FlyKart 2 was one of 10 winners of Phase 1 of the GoFly competition and one of five winners of Phase 2.

The GoFly Phase 3 fly off will take place in Feb. 2020 in the San Francisco Bay Area.

Bulaga says there are five enabling technologies that have made the Trek FlyKart 2 possible: structures, batteries, motors, propulsion and controls.

When it comes to structure, FlyKart 1 was built using aluminum tubes. For FlyKart 2, the structure is made of rectangular bonded carbon fiber tubes that provide more stiffness, are 50% lighter, but six times the cost.

Bulaga says that in the years since Trek flew its first electric drone in 2006, today’s batteries now provide twice the power density for half the cost.

“I need to thank, probably, the automotive industry, but more surprisingly was the vaping industry. The 18650 [rechargeable lithium-ion battery] is what has been going into the vaping systems, and that is what has driven down the cost.”

“As an aerodynamicist, when I started working with electric systems, I had no concept as to what the intricacies would be.”

“Batteries get hot as they discharge and you have to supply cooling air.”

Bulaga says one of the major design challenges is that an eVTOL aircraft needs a lot of the power at the end of a flight to hover for a landing, but that is also the point where a battery has its lowest voltage, “so you have to design the aircraft to land at low voltage.”

EAS 2019 #22 – Edgar Rodrigues – The Future of Urban Air Mobility

ELECTRIC AIRCRAFT SESSION
Edgar Rodrigues, Project Strategy and Business Intelligence, EmbraerX

Embraer, the Brazilian aerospace company has built and delivered 8,000 aircraft in its 50-year history.

Traffic is getting worst and the cost of urban congestion is rising. By 2050, the absolute urban population will almost double, 70% of global population will leave in urban areas, Urban sprawl is expected to increase 3.5 times.

Embraer is collaborating with others to create an Urban Air Mobility ecosystem. For example, EmbraerX, with Embraer subsidiary Altech and radar maker Harris are collaborating to create Flight Plan 2030, an air traffic management concept for urban air mobility. The Flight Plan 2030 white paper was released in May 2019.

In June 2019, EmbraerX unveiled Beacon, a business platform to streamline the aviation services ecosystem.

And EmbraerX is developing an eVTOL aircraft for the Uber Elevate aerial ride sharing network. The design features eight lift rotors, a wing and two thrusters for forward flight.

The yet to be named eVTOL aircraft is the subject of a naming contest on the Embraer website: www.embraerx.com/nameyourevtol

EAS 2019 #23 – Kevin Noertker – Leading the Charge with Practical, Compelling Electric Aircraft

ELECTRIC AIRCRAFT SESSION
Kevin Noertker, Co-Founder & CEO, Ampaire Inc.

Kevin Noertker says that it has been an “incredibly eventful year for our industry.”

He says that for the first time, the new electric-powered aircraft segment was getting a lot of attention at the Paris Air Show in June at the same time as environmental concerns were emerging as a major risk to commercial aircraft deliveries. This has presented Ampaire with an increasable challenge as well as an incredible opportunity.

Following the Paris Air Show, Noertker also said that UBS also issued a report saying that the shift to hybrid electric aircraft could happen much sooner than previously expected and estimated this could become a $200 billion market between the late 2020s and 2040 with the delivery of up to 16,000 hybrid electric aircraft in the general aviation, regional airline and business aviation market segments.

Noertker, says that, “this is a conversation that we have not heard in the past.”

“When bankers start salivating over new industries, you know that something legitimate is taking place,” added Noertker. “They don’t spend a lot of time with pie in the sky ideas.”

Noertker asked “When will a person flying an aircraft today powered by a Lycoming, Continental, Pratt & Whitney Canada or Williams engine be able to fly an aerial Tesla?”

He says that EAA members have always been driven by innovation and an interest in new technology.

Electric aircraft offer the promise of reduced operating costs, which means that private pilots will be able to fly much more and for charter and regional airlines it means they can make a profit on more routes and provide better services to underserved communities.

Noertker says the first revolution in aviation began with the piston engine used to power the Wright Flyer in 1903, and the second revolution began in the 1950s when the jet engine was introduced on passenger aircraft.

Norway is there first country in the world that has committed to using all electric aircraft to service its domestic airline routes under 90 minutes in duration. Noertker says that Ampaire seeks to be one of the first airlines to enter the Norwegian electric aircraft market.

Offering some statistics, Noertker says that aviation produces about 800 million tons of CO2, which is three percent of global emissions and ejects it directly into our atmosphere every year, “so we are paying a significant environmental cost.”

Noertker also noted that airline profitability also rises and falls “with the cost of Jet A” fuel, adding that this is especially difficult for regional airlines that struggle to be profitable as a result of high operating costs, especially on a seat-mile basis.

Small regional airlines serving smaller communities struggle to survive, and often this is only possible with government subsidies such as the $300 million a year distributed in the US under the Essential Air Service (EAS) program.

Electrification of aviation will:
– 70 to 90 percent fuel cost savings
– 25 to 50 percent maintenance cost savings
– noise reduced by two-thirds or even more
– help earn the good will of communities around airports
– significantly reduce direct emissions

Ampaire’s concept aircraft is the Tailwind with a thrust vectoring ducted fan at the rear of the aircraft.

But the company knows that such an aircraft program will require hundreds of millions of dollars and up to a decade to certify, will require ground infrastructure, and “will take pull from consumer demand and pull from government and regulatory bodies.”

So Ampaire is taking a step-by-step approach by starting in the retrofit market. It’s taking the proven Cessna 337 Skymaster airframe and transforming it into the Ampaire Electric EEL, an aircraft that is partially electric powered and partially combustion engine powered.

The prototype conversion flew for the first time in California in June 2019.

The company’s value proposition is to enabling carriers to capture frustrated car commuters:
– Save carriers $375 k to 1,260 k per plane per annum
– Reduce carrier Opex up to 70%
– Undercut cost of car commutes
– Enable return of closed airline routes
– Open travel to new routes

The aircraft configuration is unique because it was designed from the outset for an electrical propulsion system and for high passenger ride comfort.

The Alice was unveiled for the first time at the Paris Air Show in June 2019 and features a glass cockpit with fly-by-wire control and side-stick controllers.

The aircraft was holistically designed for range, speed, ease of piloting and passengers’ comfort, and to utilize current battery technology.

The Alice has been designed for aerodynamic efficiency, with slick design and lift generating fuselage; thin, clean wing with Fowler flaps; wingtip-mounted EPU and a V-tail.

The wingtip-mounted EPU features:
– Cooling challenge: no inlets, no radiators (heat exchanger conformal to the outer mold line)
– Controllability challenges and opportunities
– Propulsion power distribution optimization
– Control and monitoring, human-man interface (display) challenges

On the ground, Alice will use wheel-in-hub motors for taxiing.

The lightweight airframe structure is designed to carry heavy batteries and the low weight subsystems include low weight subsystems, including fly-by-wire computers, avionics and actuation.

Elevation has lined up a large number of partners including Rolls-Royce (Siemens) and magniX for motors.

Flight testing of the Eviation Alice will take place in Prescott, Arizona.

EAS 2019 #25 – George Bye – The Benefits of Electric Aviation, Featuring eFlyer

ELECTRIC AIRCRAFT SESSION
George Bye, CEO, Bye Aerospace

Bye Aerospace is developing the eFlyer 2 to be the world’s first certified electric aircraft.

George Bye began his presentation by highlighting that 30% of the mainline airline pilots in the United State will be retiring in the next three years.

He says that, “The ability to get from Denver to New York, Los Angles or Dallas is going to be challenged without new pilots.”

The top priority market for the Bye Aerospace eFlyer 2 is the flight training market.

The prototype eFlyer 2 made its first flight ion April 10, 2018 powered by a preproduction Siemens V9 electric motor and in 2019 the prototype received the Siemens V10 production motor, the 90 kW SP70, which has 20 percent more power and will drive a three blade propeller.

Bye says that the new engine allows the eFlyer 2 to cruise at 90 knots at 35 kW, which gives three hours’ endurance, with reserves. The aircraft has a top speed of 135 knots. And the aircraft has an “L/D of 20.6,” which reflects the aircraft’s very efficient airfoil.

In the past year, the company’s team has doubled in size and “our market has tripled in size.”

OSM Aviation Academy, a flight training school in Scandinavia (previously known as the SAS Flight Academy) that is part of the Norwegian Airlines Group, ordered 60 eFlyer 2 aircraft.

Bye says another advantage of the eFlyer 2 is its low noise signature.

Bye added that Scandinavia and Europe view electric aviation as essential, not just interesting.

Bye says that the aviation industry will require 790,000 pilots over the next 20 years, which means there has to be an eightfold increase in the number of pilot certifications annually to meet future demand.

Bye says the cost of becoming a pilot is a major barrier, and if the pilot demand cannot be met airlines will have to ground aircraft in the next decade.

Bye says other features of the eFlyer 2 include Garmin G3X avionics, a BLR full aircraft emergency parachute, and a 46-inch-wide cabin with cabin heating and air conditioning.

Bye claims that the eFlyer 2 will have one-fifth the operating costs of popular training aircraft today, including maintenance and the energy cost.

Bye says that 60,000 training aircraft will be needed to meet future training demand, and that a market of 20,000 aircraft will exist for aircraft in the eFlyer 2 class.

Bye says that the four-seat eFlyer 4 is being designed for the flight training and air taxi market. He says that this aircraft will also have one-fifth the operating costs of current four seaters, which will enable low cost air taxi service.

Earlier this year, Blackbird, an on-demand air taxi service based in San Francisco signed a memorandum of understanding (MOU) to acquire 10 eFlyer 2s and 100 eFlyer 4s and other air taxi companies are pursuing orders for the aircraft.

By EAS 2019, Bye had received commitments for over 600 eFlyer aircraft, including orders, MOUs and options.

The company has been working on FAR Part 23 certification of its aircraft for the last year and a half. The eFlyer is not a Light Sport Aircraft (LSA) or an ultralight class aircraft.

Potential future products include the high performance eFlyer X with retractable landing gear and pressurized cabin.
