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 ...
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 ]
Field-emission electric propulsion (FEEP) is an advanced electrostatic space propulsion concept, a form of ion thruster, that uses a liquid metal as a propellant – usually either caesium, indium, or mercury. [1] A FEEP device consists of an emitter and an accelerator electrode.
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).
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.
EGTS is an electric taxiing system enabling an aircraft to taxi independently of its main engines or tug. [2]Each of the two main landing gear inboard wheels is driven by an electric motor powered by the auxiliary power unit (APU) generator, allowing the aircraft to push back from the gate without an airport tug and to taxi without the use of the main engines.
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.
The AgustaWestland Project Zero is a hybrid tiltrotor/Lift fan aircraft. It has been developed by AgustaWestland as a technology demonstrator, and is used to investigate all-electric propulsion and other advanced technologies. It is the world's first electric tiltrotor aircraft. [1]
