. The global Vertical Flight Technical Society – Founded in 1943 as the American Society – Everything from VTOL MAVs/UAS to and eVTOL to STOVL . Expands knowledge about vertical flight CFD of Joby S4, Aug 2014 technology and promotes its application around the world . Advances safety and acceptability . Advocates for vertical flight R&D funding . Helps educate and support today’s and tomorrow’s vertical flight engineers and leaders

VFF Scholarship Winners at AHS Forum 71, May 2015 2 www.vtol.org

. AHS has a proud history of advocacy and support – Worked with NASA, Army and Air Force to save the NFAC wind tunnel – Helped in establishment of NASA-Army joint office, VLRCOEs, NRTC, RITA/VLC . Provided major foundational support to transformative initiatives – Joint Strike Fighter/F-35B STOVL – V-22 Osprey tiltrotor . Providing major foundational support to new transformative initiatives – Future Vertical Lift (FVL)/Joint Multi-Role (JMR) – Electric and hybrid-electric VTOL (eVTOL)

We exist to advance vertical flight!

The 20th Century proved that vertical flight was possible with combustion engines and drive systems

ASTOVL/JAST/JSF proved that the engine location could be decoupled from the center of gravity

Mechanical complexity led to high failure rate and fatal accidents for a “Wheel of Misfortune” www.vtol.org/wheel 6 www.vtol.org

. Eliminate complex rotors! – Cyclic, collective, swashplate – Transmissions, gearboxes, shafting, hydraulics, etc. . Distributed Electric Propulsion – Replace single complex system with multiple simple thrusters . Get on a wing for efficiency – Higher speed, longer range . Environment . Not this! – Noise, noise, noise! . Cars were not buggies with mechanical horses – “Tailpipe” emissions 9 www.vtol.org
