It's a Rotating Detonation Rocket Engine"

What makes the RDRE so revolutionary is that it makes use of a sustained detonation circling around a ring-shaped channel, fed by a mix of fuel and oxygen which is ignited by each passing explosion.
Crucially, the RDRE uses less propellant fuel than conventional rocket engines, and is simpler in terms of its machinery and mechanisms. That means going into space becomes cheaper, and traveling further distances becomes possible.

NASA invented a space ship powered by a rotary engine? Noice, at least until the apex seals give out, but they should be good for 80k at least.

Wankel and Mazda shine blessings upon you and your RX family

The wankel and rdre aren't really related, but they're similar in that they're both oddball engines with surprising performance.

Of all of my near future rocket engine predictions, a working aerospike rdre was not on my list... I'm honestly very impressed!
