UT Arlington Rotating Detonation Wave Engine Initial Testing Compilation

Several types of engines that utilize detonation waves have been conceptualized, of which the pulsed detonation engine (PDE) has seen the most extensive development. Another relatively unexplored concept (until recently) is the rotating detonation wave engine (RDWE). This engine uses an annulus placed perpendicular to an inlet and nozzle system whereby a detonation wave continuously travels around and detonates the incoming propellants to produce axial thrust. The engine, if successful, can be more efficient than a PDE because it eliminates the need to purge between detonations and has a more steady inlet and nozzle. Experimental research into this engine was made possible by a NSF LSAMP undergraduate research scholarship. The video shows initial testing of two engines, where some success is seen in the later clips. The tests are usually short since the data acquisition rate is high enough to produce a large amount of test data in a fraction of a second.

so how would these be used to power cars? or do we have to jet everywhere like batman :3

With exhaust like this, I'm pretty sure it would be better to connect it to a turbine and electrical power generator and then figure out how to make everything quiet.

em8, how long to your knowledge have PDE's been theorized for?

one last thing is, what fuel will be used for these engines?

liquid methane?

[emb8]

PDEs have been theorized for at least 70 years, and ways to use detonation for useful purposes have been considered for over 100. All kinds of fuels can be used, including hydrogen, methane, kerosene, etc.

Can I use that to roast a marshmallow?

[thesantiso]

Such great power for such a short period of time... I hope you get to something with this. I would love to see that engine running smooth

This is being used on the new Perseus anti-ship & land-attack stealth supersonic cruise missiles for the Royal navy the most advanced in the world.

Nice test of your CWDE. Your water-cooled photocons are leaking because you are using the wrong tubing for this type of test. Your PCB's are also leaking because you are probably using the wrong seal material. How long have you been testing these types of engines?

[preludeAchris]

more like 10-15000

[preludeAchris]

then all the Honda guys are going to say my vetc goes prrgsshhhhhhhhhhhhhh
