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 .
The power capabilities of a modern electric propulsion system based on batteries are to be demonstrated with the e-Genius. In addition, Eric Scott Raymond and his team participated in the Green Flight Challenge of the Comparative Aircraft Flight Efficiency (CAFE) in the summer of 2011 in Santa Rosa, California with this aircraft, finishing ...
The Northrop Grumman XRQ-73 SHEPARD (Series Hybrid Electric Propulsion AiRcraft Demonstration) is an tailless flying wing hybrid-electric Group 3 unmanned aerial vehicle (weighting about 1,250 lb (570 kg)) developed by Northrop Grumman.
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 ...
It follows previous electric flight demonstrators: Cri-cri, e-Genius, E-Star and the E-Fan 1.2. It will anticipate a safe, efficient, and cost-effective hybrid single-aisle airliner. Airbus and Siemens have collaborated since April 2016 on the E-Aircraft Systems House for electric propulsion components, including ground tests.
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.
Beamed propulsion in the form of a laser can send power to a photovoltaic panel for Laser electric propulsion. In this system, if a high intensity is incident on the solar array, careful design of the panels is necessary to avoid a fall-off in conversion efficiency due to heating effects.
A plasma propulsion engine is a type of electric propulsion that generates thrust from a quasi-neutral plasma. This is in contrast with ion thruster engines, which generate thrust through extracting an ion current from the plasma source, which is then accelerated to high velocities using grids/ anodes .
