Wave Engine Corp has aced a demonstration flight of a simple jet engine with no moving parts. A modern version of a pulsejet, the J-1 engine powered a UAV through take-off and several mid-air stop ...

In an effort to create a simpler, more affordable form of jet propulsion, University of Maryland spinoff Wave Engine Corporation has developed a digitally controlled modern-day pulsejet engine for ...

Bob Maddox once built the world’s largest pulse-jet engine and mounted it in a 1965 Jaguar. Star Wars audio engineers even recorded his pulse-jet engines for the movie Solo.

In fact, valveless pulse jets used by Maddox feature no moving parts at all. Instead, they rely solely on the acoustic resonance designed into the engine’s intake, combustion chamber, and exhaust.

Our SoundClip series continues with listener Larry Cottrill, who provides audio of a homemade pulse jet engine. It's very loud and very simple, and it can't be muffled. Therefore, it is ...
