YouTuber develops innovative open-source resin 3D printed shockwave jet engine prototype 

Youtuber Integza has developed a functional open-source resin 3D printed prototype of a detonation-powered pulsejet engine.  While pulsejets, valveless engines in which fuel is injected into a pipe before being ignited in a series of pulses, have been around for over a century, they tend to emit a low specific impulse. These lightweight propulsion systems […]
