Inside a jet engine, temperatures soar beyond the melting point of the very metal that holds the machine together. So how does it stay intact? Engineers use advanced materials, hollow blades, and ...

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 ...

There are many components that go into a jet engine, from combustors to compressors to those gigantic fans that are a staple of engine design. Many of these things are also found in the engines of ...
