All-electric air mobility solutions manufacturer Eviation Aircraft has selected Piqua, Ohio-based Hartzell Propeller Inc. as a development partner for its all-electric Alice aircraft. With, Plans are for the zero-emissions, 100% battery-electric propulsion Alice aircraft to be test flown at the 53rd Paris Air Show in June 2019. Under the terms of the development partnership, Hartzell Propeller will provide customized and optimized propellers and support systems.
Alice uses distributed propulsion with one main pusher propeller at the tail and two pusher propellers at the wingtips to reduce drag, create redundancy, and improve efficiency. The aircraft is designed to take 9 passengers and 2 crew up to 650 miles at a cruise speed of 240 knots on a single charge.
Founded in Tel Aviv in 2015, Eviation is led by a team of aviation and technology leaders from organizations including Phinergy and the Israel Defense Forces. With a 900kWh Li-ion energy pack, Eviation's Alice will provide high-energy density, battery-powered fleets to regional carriers in the U.S, with a value proposition that can reduce carrier operating expenses sustainably.
"Eviation's new regional commuter aircraft provides an exciting opportunity to be a part of the next generation in aircraft powered by electricity," said Hartzell Propeller President Joe Brown. "And it is another example of manufacturers utilizing our expertise in supplying propeller systems designed to optimize performance specifically for their aircraft and mission profile."
"Hartzell is an industry icon in aviation for its innovative propeller designs. It is largely responsible for the two precursors to our battery-power engine – the turboprop propeller and the piston-engine, so we welcome them as a valued partner, as together we chart this new era of electric aviation," said Omer Bar-Yohay, CEO of Eviation.
With development support from Hartzell Propeller, the Alice will be equipped with an innovative system of new propellers, designed to meet the unique needs of the first-in-kind aircraft. The design and manufacture of the propeller systems underway will use Hartzell's 5-blade carbon fiber blades and Bantam hub series to reduce weight and achieve maximum performance.
Each of the propellers in the three-unit ship set will be approximately 65" in diameter and feature carbon fiber blades with nickel cobalt leading edges, certified for unlimited life. The structural composite propellers will be integrated with Eviation's proprietary technology advances, including: thermal management and autonomous landing, distributed electric propulsion, and composite body frames.
Eviation is a member of NASA's on-demand mobility program, and serves on the electric aviation committees of the General Aviation Manufacturers' Association (GAMA) and the U.S. Federal Aviation Administration (FAA).
