Pulsed Detonation Engine 1 Hz Ground Test with Arc-igniter

[bababooooo]

So whats the 1Hz for is it like my laptop the more Hz the stronger it is and whats the max Hz can it achieve?

[rbneville]

@bababooooo Hz is a measure of times per second. In this video 1hz means that there is 1 pulse every second.

By the way it's not the g force in Orion that was the problem it was the emp effect cause by the ultra high energy gamma rays stripping the electrons of the atom and cause them to act ass free electrons, the electrons then follow the flow of the earths magnetic fuel and shoot down ward frieing every cercuit it's one massive electromagnetic pulse

[IAbominator]

U people need to do some research a human would be able to survive the g force if it's in a straight line also haven't u heard of new projects I forget the names but they use anti matter pulses one use plasma accelerated by high voltage superconductors to achive nearly light speed in space another is the nuclear electric rocket seriously Orion isn't the only one plus they would be able to survive

[MANDELBROT27]

Yeah thanks i will.How much G force do you geuss there would be? Is there anyway of making a calculation? Great Video

[MANDELBROT27]

Didnt some guy(s) try to send a "ship" into space using massive explostions (nuclear?) as thrust.

@MANDELBROT27 That is a theory that came out not long after atomic bombs were used - look up Project Orion. I can't imagine a human surviving the g-force from an engine like that starting up.

@emb8 One of the absolutely crucial design features of the Orion project was the combination of pusher plate and shock absorbers needed to keep the g-force shock to a tolerable level. We're talking thousand-ton solid metal pusher plate and 20-foot travel on the absorbers.

Why is it that after every detonation there is a second flame visible?

[emb8]

Each cycle consists of filling with combustible gases, detonating the mixture, and then purging with air before repeating. The second flame appears when the purge air pushes out the detonation products, which are very hot.

[lbochtler]

that engen delivers a hell of apunch, look at the camara muving wile its firing. XD

[smilingpug]

Also, is this using an electric arc plasma torch?

[smilingpug]

This PDWE sounds WAY more like what they are supposed to leave as a contrail. The other posts' engines do not sound like this one.

[jeffpolara]

Is there a future for vehicles that use Electro Plasma Pulse technology?

[emb8]

There is a lot of ongoing work with plasma. Generally, engines using plasma are suitable for space applications since they produce low thrust but over a long time. They don't scale to aircraft, but fields like plasma-assisted combustion will probably lead to more efficient high-speed engines.

[jeffpolara]

Thanks for posting this video and thanks for your answer to my question.

[SINKID3]

this really is rocket science when i grow up i want to be an aerospace engineer

[spiralspines1]

Oh yeah! I'm one(in the making)!

[atticusgen4]

Hmmm. Im confused. What exactly is going on in this video?

[emb8]

Since the engine is operating at 1 Hz, that means every one second fuel and oxidizer is pumped into the detonation chamber inside the engine. The mixture then detonates with the help of a plasma ignition source, like a spark plug only much more advanced. The detonation-induced shock front exits the engine and causes thrust. The pulses here were purposely slow due to some data aquisition reasons.

[honda4004]

hi could you state voltage of plasma and what it actually was used to do this thanks

[emb8]

Unfortunately I cannot state the details of the plasma ignition system. However, if you want to get an overall idea of it you could have a look at AIAA papers 2008-1097 and 2007-631. These papers don't present PDE research but the plasma systems are manufactured by the same company.
