Homemade Pulse Detonation Engine attempt

This is an engine that i built in my spare time during the christmas holidays.
I'm not positive that it is detonating the fuel but it certainly is powerful and it is VERY VERY loud. If a tissue it put in the exhaust it gets shredded. If you have any questions about it post a comment or message me.

what is the fuel?

[rmoss15]

Propane and air

[theartilerysheller1]

nice engine it kinda sounds like drums

how did you make it

and what was the fuel and ignition

[rmoss15]

It is made from a Cast Iron combustion chamber with a mild steel tailpipe. The fuel is propane and the ignition is a high powered jacobs ladder circuit going through a spark plug.

Btw when you're next to it or even 20 metres from it, it makes your ears ring which is why if you make one, invest in some really good ear muffs.

lol in the beginning it sounds like a bar fight (2)

Hauhauhauhauahuah

How did you build this? Did you have instructions? It's very cool...

[233kosta]

I'd have thought with a bit of fine tuning you'll have this running like a treat

[syalcin123]

very well, but i think you must not keep those batteries near hot engines that blow flames

[nickflame9]

its very cool, but i can say that is NOT detonation, that is deflagration, as detonation will be louder and sharper than that.

Detonation or not ... the neighbors must love you!!!

I inadvertently achieved detonation with my pulsejet engine by injecting O2 into the combustion chamber. It blew all the reed valves threw the valve plate. LOL

Nice work in all your vids! Instant Sub.

peace

Wow way to go. I call mine explosive resonators because the smart people at NASA and John Hopkins said that we are to stupid to make a pulse detonation motor. They are far superior to pulse jets. How about that blast. They also said that you can not make one for propane. Also they don't get hot because they are efficient. The experts had all the money, materials, and fuels in the world and they do not know what you know. You sure got a lot of comments.

sounds like a 20mm AA gun.
