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 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 ...

A modern jet engine is a complex mechanical wonder. However, these aren't engines that will just roar into action with the turn of a key or the press of a button. Often, turbine engines will need ...

Supercomputers are capable of a mind-boggling number of calculations and one of them just found a flaw in a piece of ...

The world’s heavy reliance on fossil fuels, especially for transportation, has left a deep mark on both the planet and public health. Burning these fuels releases a flood of greenhouse gases, which ...

Bob Maddox’s stage name, Crazy Rocketman, is a misnomer. Maddox doesn’t build rockets. He builds pulse-jet engines. There’s a difference. As for the crazy part—that may be true. Maddox is the world’s ...
