So what's its I_SP ?

[sit-rep]

question for the all knowing out there...

in atmosphere the speed is determined by the power of thrust against basicly air resistance. in space there is no resistance. so is it safe to assume that as long as the rocket is thrusting, the craft will continue to gain speed? and if so, to what end? i cant imagine if there was enough fuel for lengthy burn for the craft to reach light speed... ...or could it??

Read the story, watched the video, still no explanation of WHAT Rotating Detonation Rocket Engine (RDRE) is.....?

[BereanBrain]

for those asking, you are not just (IGNITING) fuel with a RDE. You are DETONATING fuel. Thus a detonation engine can produce more thrust (and at a higher speed) than just plain IGNITION.

There is a reason when launching rockets the say 3.2.1 IGNITION.

One day, we will say 3.2.1.DETONATION.

Sounds dangerous, no?

All this is Physics 101, sorry guys, but it’s elementary science

Is this a spike rocket engine? They keep changing the name.
