This technology came about owing to major advances in electric propulsion (motors, batteries, fuel cells, electronic controllers) and the emerging need for new aerial vehicles for Advanced Air Mobility and Urban Air Mobility that can enable greener and quieter flights. Electric and hybrid propulsion systems (EHPS) have also the potential of ...
The e-Genius follows a line of airplanes with alternative propulsion systems, which have been developed at the Institute of Aircraft Design under the leadership of Professor Rudolf Voit-Nitschmann: the solar-motor glider Icaré II (1996) and the predecessor of the e-Genius, the motor glider with a fuel cell propulsion system – Hydrogenius (2006).
An electric propulsion system also includes a power inverter, while fuel engines have a fuel system themselves. The 750 shp (560 kW) experimental magniX magni500 electric motor weighs 297 lb (135 kg), [ 136 ] while the 729 hp (544 kW) certified Pratt & Whitney Canada PT6 A-114 weighs 297 lb (135 kg), [ 137 ] both powering the Cessna 208 Caravan .
In aeronautics, Distributed propulsion is an arrangement in which the propulsive and related air flows are distributed over the aerodynamic surfaces of an aircraft. The purpose is to improve the craft's aerodynamic, propulsive and/or structural efficiency over an equivalent conventional design.
Lilium says that it refers to the propulsion system as a "jet" because the propellers are enclosed in nacelles. [11] The production Lilium Jet is intended to accommodate six passengers and one pilot. It is powered by 36 electric motors, six on each of the two front canards and twelve on each rear wing.
Hydrogen fuel could save £150,000–£300,000 annually over fossil fuel, maintenance costs should fall by 50% for the propulsion system, and 15% for the whole aircraft. [5] Rolls-Royce plc left the consortium, while engineering company Ricardo plc will integrate the two 250 kW (340 hp) fuel cells and Innovatus Technologies the composite ...
The General Electric XA100 is an American adaptive cycle engine demonstrator being developed by General Electric (GE) for the Lockheed Martin F-35 Lightning II and forms the technological foundation for the company's XA102 propulsion system for the United States Air Force's sixth generation fighter program, the Next Generation Air Dominance (NGAD).
The use of EHD propulsion for lift was studied by American aircraft designer Major Alexander Prokofieff de Seversky in the 1950s and 1960s. He filed a patent for an "ionocraft" in 1959. [ 4 ] He built and flew a model VTOL ionocraft capable of sideways manoeuvring by varying the voltages applied in different areas, although the heavy power ...
