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
So this is a mini-Orion pulse detonation type engine.
