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 ...
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 ...
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.
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.
An example of integrated electric propulsion in the Type 45 destroyer (GT: gas turbine; DG: diesel generator) Integrated electric propulsion (IEP), full electric propulsion (FEP) or integrated full electric propulsion (IFEP) is an arrangement of marine propulsion systems such that gas turbines or diesel generators or both generate three-phase [1] electricity which is then used to power ...
The 1,300-shp GE Catalyst could be used in hybrid-electric propulsion: in late 2016, General Electric modified a GE F110 fighter turbofan to extract 250 kW from its HP turbine and 750 kW from its LP turbine, supported by the USAF Research Laboratory and NASA, developed and tested a 1-megawatt electric motor/generator with GE Global Research ...
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 ...
