AHS International is pleased to announce that the Society is rebranding to better reflect our membership and our role in the world.

After years of discussion and months of debate, the Board of Directors of AHS International voted to change the identity of AHS to the “Vertical Flight Society,” the moniker that the Society had been using in various forms for at least a half century. While not a legal name change, the “Vertical Flight Society” will become the “trade name” for AHS.

Bratislava, Slovakia-based AeroMobil s.r.o. was founded in 2010 to develop vehicles that can convert from street-legal automobiles to aircraft, though the AeroMobil design has been in development since 1990. The company flew its 3.0 short takeoff and landing (STOL) design in 2013 and announced its 4.0 production model in April 2017, capable of STOL operations from 650 ft (200 m) grass strips; the company is currently taking pre-orders for the vehicle.

AHS International Executive Director Mike Hirschberg hosted a panel discussing the promise, progress and challenges of electric VTOL aircraft development. More than 50 companies are currently developing eVTOL aircraft (see the AHS website, www.eVTOL.news), with several in advanced stages of flight testing. Industry experts expect these new products to enter the market in the next 5-10 years, and expand the operational opportunities for rotorcraft operators, due to their extremely low noise and low operating costs.

A packed house at January’s AHS International Transformative Vertical Flight Technical Meeting and Fifth Annual Workshop learned about bold visions for urban air taxis and the challenges of electric vertical takeoff and landing (eVTOL). Four days of presentations hosted by the AHS San Francisco Bay Area Chapter covered aeromechanics, propulsion, acoustics, infrastructure and certification advances aimed largely at airborne mass transit. The new rotorcraft suggested for moving people over clogged streets include multicopters, tiltrotors, tilt wings and ducted fans, nearly all designed around Distributed Electric Propulsion (DEP). AHS International executive director and workshop program chair Mike Hirschberg observed, “Really, transformative flight is [largely] about DEP and the design freedom that it enables.”

Vahana, the all-electric VTOL aircraft from A³ by Airbus, made its first full-scale flight on Jan. 31, 2018, at the Pendleton UAS Range in Pendleton, Oregon. The first untethered flight of the unmanned, fully self-piloted electric vertical takeoff and landing (eVTOL) demonstrator was a 53-second hover at 16 ft (5 m). A³ completed a second flight of the first demonstrator, dubbed “Alpha One,” the following day with representatives from the US Federal Aviation Administration (FAA).

Advanced VTOL Demonstrators Accelerate Full Tilt

Joby Aviation, Inc., which went silent in late 2016 shortly after telling Vertiflite that it would fly in early 2017 (“The Demand for On-Demand Mobility, Vertiflite, Jan./Feb. 2017), revealed on Feb. 1, 2018 that it is well advanced in its flight testing of its four-seat S4. Although the company has still not revealed any images of the S4 since the AHS-led 2nd Transformative Vertical Flight Workshop in August 2015 (shown), the company officially announced on Feb. 1 that it has been flying the eVTOL aircraft and that it is “now developing a commercial version of that design and preparing that vehicle for certification.”

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.
