So imagine you've got a series of repeated detonations. matched

That's what they did called a pulse detonation engine. matched

The big problem, though, is that by its very nature, it's not generating thrust all of the time. matched

It's doing it in these discrete pulses. matched

But it was a good proof of concept. matched

The second type of detonation engine is the rotating detonation engine. matched

This one's really interesting and much better than the pulse engine. matched

Shock waves from one detonation are tuned to trigger detonation. matched

subsequent detonations by basically creating a rotating detonation wave within this ring-shaped channel. matched

That's a valid process, but engineers thought that this was impossible until the University of Central Florida demonstrated one last year. matched

These guys are awesome, but that's not even the best thing that they've done. matched

These are the guys that now created this third type of detonation engine. matched

This is the oblique detonation wave engine, ODWE. matched

This lab experiment, this experimental engine that they made, this is what it was. matched

It was this third type of detonation engine. matched

So try to imagine this. matched

Now you have a mix. matched

You're creating a mix. matched

In this experiment, they had hypersonic speeds. matched

They had air moving at hypersonic speeds. matched
