UT Arlington Pulsed Detonation Engine 25 Hz Ground Test

This pulsed detonation engine was built and tested in 2005 at the UT Arlington Aerodynamics Research Center. This engine uses solenoid valve fuel injection and a modified automotive ignition system with hand built tungsten electrode spark plugs. The tube inner diameter is 25 mm. The PDE is running on a mixture of propane and oxygen at a detonation frequency of 25 Hz.

Let me see now. If I want to move my car with these, I'd need some ten or twenty, right? If thirty, I'm completely going to love this stuff just for the sound.

unfortunately, PDE's don't seem too likely to replace current engines. They're loud, have vibration issues, some lack rotatory shafts to drive generators/accessories, use exotic fuels, etc. Plus conventional engines are getting more efficient every few years. Not saying it wouldn't be cool, but they have a long long way to even catch up with todays jets.

I want one!!!

@MrMicraphone It would either just fall off the bike, rip the bike in half, or work, but cause you to go from standing, mach 1 in a few seconds and your body would be crushed.

@nickcars100 No aurora runs on imaginatium sir.

No seriously, the Aurora doesn't even exist.

What's the thrust gain vs a jet engine, pound per pound?

@nickcars100 When Elvis is flying it, he fills it up with gas.

@nickcars100 The Aurora fuel is 2*(hydrogen) + 1(imagination)
