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 ...

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 ...

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 ...

Jet engines are built to terrifyingly tight tolerances, yet the latest simulations on the world’s first exascale supercomputer suggest their biggest weakness may be measured in micrometers.

The rotating detonation ramjet engine provides a more compact, lightweight design than standard engine designs, and uses a continuous, self-sustaining detonation wave. GE Aerospace and Lockheed Martin ...
