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

[emb8]

@Pimpmastahanhduece 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.

[Ecurrie84]

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]

@Ecurrie84 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.

@emb8 To my knowledge the US have gone with a hydrogen slushy for better fuel stabilization. Under code name aurora, witch is blanket code name for all extreme propulsion experimental craft including the TR-B series 1 threw to classifided..

[bigtopbollocks]

Why did they drop the aerospike on the air cde ?

[superbungabunga]

i think we need more O2 it isnt big enough yet

[EliteSniperFMJ]

is this similar to the scram jet engines of the aurora which is rumored to fly of speeds in excess of mach 10...7000 mph

[rictorven]

O.O......
