A hybrid-electric jet engine may seem as absurd as a horse-drawn Zeppelin, but GE Aerospace is ground testing a new megawatt-class hybrid turbofan engine and its full powertrain that is powerful ...

Five years ago, in 2021, American space agency NASA announced it is working on yet another project that doesn’t involve, well, space: the Hybrid Thermally Efficient Core (HyTEC). Since then, NASA’s ...

RTX reached a full-power test milestone on its hybrid-electric propulsion demonstrator, achieving 1MW motor rated power, ...

The idea of a hybrid-electric engine for supersonic aircraft may elicit a similar initial response, but there is some very firm engineering logic behind it. Put simply, conventional supersonic engines ...

Rolls-Royce is developing a hybrid jet engine designed to reduce flight emissions by roughly 30%, a target that places the British manufacturer squarely in a high-stakes race among engine makers to ...

GE and Lockheed ground tested a new air-breathing hypersonic jet engine capable of powering missiles to speeds well in excess of Mach 5 in a smaller, cheaper, lighter, and more efficient package than ...

Engine maker GE Aerospace and defence manufacturer Lockheed Martin have teamed up to test a novel ramjet propulsion system for powering hypersonic flight. The pair say they completed a series of ...
