XTI Trifan 600 Ducts

XTI Aircraft Prototype Begins to Come Together

XTI Aircraft announced on Feb. 20 that it was on schedule and on budget as it completed the ducts and fans for its 60% scale flying prototype of the TriFan 600 aircraft, and moved toward ground testing those components (see “XTI Aircraft Refines Its TriFan 600 VTOL BizJet,” Vertiflite March/April 2018). The wing ducts for the prototype were received from Trek Aerospace in late March: the photo shows XTI founder Dave Brody (second from left) with the two ducts. “In this Phase 2,” explained Robert LaBelle, Chief Executive Officer of XTI, “we’re fabricating the wing ducts and fans and will perform ground tests for static thrust performance and verification on those components. We’ll also complete weight and balance, and full structural design. Fabrication of the entire aircraft will be completed in Phase 3, which will begin in April, followed by two or three months of testing before first flight later this year.” The company said it had received 60 orders for the airplane — each with a $25,000 refundable deposit — representing $390M in sales.

XTI Aircraft Refines its TriFan 600 VTOL BizJet

XTI Aircraft Refines its TriFan 600 VTOL BizJet Will the civil air transport sector accept a regional VTOL aircraft that is not a tiltrotor? Vertiflite looks at one company’s offering. By Robert W. Moorman Vertiflite, March/April 2018 Vertical takeoff and landing (VTOL) -capable aircraft other than helicopters are not yet part of business and commercial aviation fleets. But that could change someday. Although there is much work going on right now on fully-electric VTOL aircraft for the Uber Elevate mission and other intra-city applications (see “The eVTOL Is in the Details,” pg. 42), larger aircraft and longer distances will require hybrid-electric propulsion solutions in the foreseeable future. One contender is XTI Aircraft Company, which is well advanced with its TriFan 600, a hybrid-electric VTOL-capable aircraft now expected to enter production in 2022, two years earlier than originally planned, according to XTI CEO Robert LaBelle. Like many companies, XTI had its challenges early on. It was founded in 2012 by entrepreneur David Brody, who came up with the conceptual design of the TriFan 600. Based near Denver, Colorado, the company’s initial plan was to develop a more traditional propulsion system for the aircraft with two large turboshaft engines driving two tilting ducted propellers and a third fan in the fuselage. But the aircraft was heavy and expensive with a $12M price tag and therefore would likely have found a much smaller market. The program suffered a setback on Feb. 5, 2016, when XTI CEO Jeffrey Pino, the former president of Sikorsky Aircraft (and former chair of AHS International), was killed after his World War II P-51D Mustang crashed near Maricopa, Arizona. LaBelle became CEO in January 2017. During a lengthy interview with Vertiflite, LaBelle detailed changes to the design of the TriFan 600, the path to its certification and the direction of the company. A New Beginning One of LaBelle’s first priorities as the XTI leader was to come up with an efficient and lighter powerplant for the TriFan 600 that would reduce the unit and direct operating costs of the aircraft. Engineers determined that a hybrid-electric system would produce the most cost-effective and marketable solution. XTI brought in George Bye as chief engineer for the TriFan 600 program. Bye’s Denver-based company, Bye Aerospace, has experience in hybrid-electric propulsion and solar-powered aircraft. Bye developed the hybrid-electric propulsion system for the TriFan 600. Another key partner in the program is Trek Aerospace, which has unique duct and fan technology. Trek said that its core technology has the highest thrust-to-power ratio in the industry, so its shrouded props require less power, meaning greater range, payload capacity and endurance. The redesigned TriFan 600 will be powered by a hybrid-electric propulsion system composed of a single 1,000 shp (750 kW) engine, such as the Honeywell HTS900, driving three generators, which, in turn, will provide electricity to the six electric motors that turn the three fans. In addition, in the vertical flight phase, the aircraft will be supplemented by batteries to provide needed power to the …

XTI Aircraft TriFan 600

TriFan 600 XTI Aircraft Company Englewood, Colorado, USA “Using three ducted fans, the TriFan 600 lifts off vertically and in seconds the two wing fans rotate forward for a seamless transition to high-speed flight. Within just 90 seconds, the airplane reaches cruise speed — where the lift is provided by the wings just like every other fixed-wing airplane. The fuselage-mounted fan, no longer needed, closes up. The airplane flies directly to its destination and reverses the process. Landing vertically right where it needs to be — wherever there’s a clear helipad-sized paved surface.” XTI Aircraft unveiled its TriFan 600 in August 2015 with a well-publicized equity crowdfunding (see “Industry Briefs,” Vertiflite, Nov/Dec 2015). The six-seat, fixed-wing airplane uses three ducted fans to power the aircraft from vertical takeoff and landing to 340 kt (630 km/h) and a range of 650 nm for VTOL or 1,200 nm (2,222 km). The company is currently building a two-thirds-scale technology demonstrator powered by a single HTS900 turboshaft engine with first flight planned for September 2018, and a full-sized prototype in November 2019. The new XTI chief executive Bob LaBelle, formerly the CEO of AgustaWestland North America, announced in the March/April 2017 issue of Vertiflite that the TriFan 600 would feature a hybrid-electric drive system. Additionally, it was announced Trek Aerospace would partner on this project, providing top-of-the-line fans, extending the aircraft’s maximum range and increasing endurance.

Uber Flying Taxis in Dubai

Is 2020 Really Possible? (sidebar)

Is 2020 Really Possible? Sidebars to From the Ground Up: Uber Elevate in 2020 Uber said that by the time flight demonstration programs begin in 2020, they will have to validate that they have mitigated the three biggest risks: efficient flights (airspace acceptance), noise (community acceptance) and safety (passenger acceptance). Note that Uber is not funding the development of the aircraft, but is helping to facilitate connections between investors and developers. Once the companies prove their products can operate within the Elevate network and meet the performance and economic requirements, Uber said it would be ready to put its money down and guarantee production volumes and revenues to justify the certification expense. To make the Uber Elevate vision a reality, the flight demonstrations to begin in 2020 will require: Demonstrator aircraft: More than two dozen organizations are currently researching electric and hybrid-electric eVTOL concepts. At least six are currently conducting full-scale flight tests, while several others are completing their aircraft or flying subscale models. Vertiport infrastructure: Uber is working with charging companies like ChargePoint, as well as Hillwood Properties, one of the largest private real estate developers and investors in the US, to establish vertiports at company-owned sites to conduct the tests with distributed nodes around Dallas-Ft. Worth. Similar efforts are underway for Dubai. Airspace: A key aspect of the Elevate ecosystem is the ability to seamlessly operate in Class B airspace. With high-speed, very quiet aircraft, Uber believes eVTOL aircraft will be able to operate in well-defined corridors linking the vertiports, and avoid the airspace restrictions imposed on ad hoc helicopter operations today. Regulations / Certification: The FAA is considering fixed-wing aircraft that take off vertically to be governed under Part 23 as small aircraft. Uber said it hopes that the new eVTOL aircraft can be certified by 2023, but that it has other ways to test the Elevate network before then. In August 2017, the FAA introduced fundamental changes to Part 23 light aircraft certification rules that are designed to facilitate innovation and reduce certification costs. And EASA recently introduced “proportionality” for light aircraft, where manufacturers are allowed to build up to 10 aircraft prior to certification. The FAA is also considering this approach. Pilots or Autonomy: Uber said it plans to fly piloted aircraft for the first five years or so to guarantee safety and develop a database of safe operations in wide-ranging conditions. For this, Uber may need tens of thousands of pilots. The company is working with groups to hire pilots with prior military aviation experience. eVTOL Companies The following electric VTOL aircraft are known to be under development. These include aircraft for a wide range of missions, not just applicable for Uber’s Elevate mission.
