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.

A prototype ion engine that uses lithium vapor as a propellant has aced its first tests, achieving 25 times more power than ...

Jet engine technology is among some of the most advanced means of propulsion in the skies today. From commercial airlines to military fighter planes, these massive engines can be heard roaring ...

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 ...

Rolls-Royce and easyJet have achieved a world-first by running a modified Pearl 15 jet engine on 100% hydrogen at full take-off power during ground tests at NASA’s Stennis Space Center. The test ...
