Prof. An Tao from the Shanghai Astronomical Observatory (SHAO) of the Chinese Academy of Sciences has proposed a novel "precessing magnetic jet engine" model to explain the peculiar gamma-ray burst ...

Printing a model jet engine is quite an accomplishment. But it wasn’t enough for [linus3d]. He wanted to redesign it to have a turbojet, an afterburner, and a variable exhaust nozzle. You can see how ...

To demonstrate the system, the researchers showed that it could reconstruct real-time high-quality still images of a model jet engine rotating at about ∼2170 rpm (top images) and a CPU cooling fan ...

The Rolls-Royce UltraFan could be the powerplant of choice for next-generation aircraft.

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 ...
