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).
Atmosphere-breathing electric propulsion, or air-breathing electric propulsion, shortly ABEP, [1] is a propulsion technology for spacecraft, which could allow thrust generation in low orbits without the need of on-board propellant, by using residual gases in the atmosphere as propellant.
Due to this lower thermal velocity, chemical propulsion units become exponentially less effective at higher vehicle velocities, necessitating the use of electric spacecraft propulsion such as PPTs. It is therefore advantageous to use an electric propulsion system such as a PPT to generate high interplanetary speeds in the range 20–70 km/s.
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 .
Experimental regional aircraft retrofitted with fuel cell-electric propulsion systems have flown in 2023. In January 2023, ZeroAvia flew a Dornier 228 with one original Honeywell TPE 331 turboprop engine on the right wing and a proprietary ZeroAvia hydrogen-electric engine on the left wing. [ 49 ]
The Advanced Electric Propulsion System qualification thruster inside one of the vacuum chambers at NASA Glenn’s Electric Propulsion and Power Laboratory. Advanced Electric Propulsion System ( AEPS ) is a solar electric propulsion system for spacecraft that is being designed, developed and tested by NASA and Aerojet Rocketdyne for large-scale ...
Microwave electrothermal thruster, also known as MET, is a propulsion device that converts microwave energy [1] (a type of electromagnetic radiation) into thermal (or heat) energy. These thrusters are predominantly used in spacecraft propulsion , more specifically to adjust the spacecraft’s position and orbit.
