An aircraft propulsion system. The system comprises an internal combustion engine configured to drive a first propulsor and an electric generator. The system further comprises an electric motor or motors each configured to be powered by electric power provided by the generator, and configured to ...
Electric Aircraft Propulsion and How it Works There’s more than one way to propel an airplane. While it’s true that most aircraft engines today run on fossil fuels, electric technology will change the way we think about aircraft propulsion. ...
Promising propulsion concepts such as electrification and hybrid-powered flight will revolutionise the future of flight.
The present work is a survey on aircraft hybrid electric propulsion (HEP) that aims to present state-of-the-art technologies and future tendencies in the following areas: air transport market, hybrid demonstrators, HEP topologies applications, aircraft design, electrical systems for aircraft, energy ...
Next-generation hybrid military vehicles, hybrid electric aircrafts and emerging urban air mobility platforms will require new integrated propulsion systems. To increase the fuel efficiency and flight times for these applications, the volume, weight and power density of the electric motors need to be ...
Hybrid-electric propulsion systems, which combine traditional engine systems with batteries, are the most technologically mature of these alternatives (which also include all-electric and hybrid-hydrogen systems). This maturity means that hybrid-electric systems will be viable onboard commercial aircraft ...
Tarbes, France - December 5, 2023-EcoPulse, the hybrid-electric distributed propulsion aircraft demonstrator jointly developed by Daher, Safran and Airbus to support aviation’s decarbonization roadmap, has successfully performed its first flight test in hybrid-electric mode. The demonstra...
Against a background of increasing energy demand and rising fuel prices, hybrid-electric propulsion systems have the potential to significantly reduce fuel consumption in the aviation industry, particularly in the lighter sectors. By taking advantage of both electric motor and internal combustion engine,...
