D-Propulse previews an air-breathing rotating detonation engine with aerospike nozzle

A startup called D-Propulse showed a preview of its air-breathing rotating detonation engine (RDE) with an integrated aerospike nozzle.
The post explains the key idea: unlike conventional jet and rocket engines that rely on deflagration, an RDE uses continuous supersonic shockwaves in a circular chamber to harness controlled explosions for thrust. The author frames it as a striking glimpse of a new propulsion approach.
