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 .
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 ...
Advanced air mobility (AAM) are systems that incorporate support for next-generation transport such as such as remotely piloted, autonomous, or vertical take-off and landing (VTOL) aircraft. [1] [2] [3] This includes those powered by electric or hybrid-electric propulsion. [4] AAM seeks to support unmanned aerial systems (UAS) and sustainable ...
Electrogravitics is claimed to be an unconventional type of effect or anti-gravity force created by an electric field's effect on a mass.The name was coined in the 1920s by Thomas Townsend Brown, who claimed to have discovered such an effect and spent most of his life trying to develop it and sell it as a propulsion system.
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.
Hybrid-electric systems use a combination of internal combustion engine (ICE) and electric propulsion system components. Different combinations are possible. [48]: 19–20 These systems can provide combined advantages from different energy sources, but still must be viewed in terms of the overall system's efficiency. [45]
An aircraft engine, often referred to as an aero engine, is the power component of an aircraft propulsion system. Aircraft using power components are referred to as powered flight. [1] Most aircraft engines are either piston engines or gas turbines, although a few have been rocket powered and in recent years many small UAVs have used electric ...
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 ...
