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 ...

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 ...

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 ...

Supersonic flight is edging back into the mainstream, but this time the race is not just about speed, it is about efficiency and emissions too. A new US UK effort to build a Mach 3 hybrid electric ...

GE Aerospace reported that it has conducted more than 3 million hours of supercomputing simulations during the past three years in its effort to define new commercial jet engine technology. It is ...
