Detonation Engines

Experimental engines that burn fuel by a supersonic detonation wave instead of ordinary slow combustion, which promises higher efficiency for aircraft and rockets. A technology belongs here when its cited article describes a pulse or rotating detonation engine. It excludes conventional jet and rocket engines that use steady burning. Detonation waves burn fuel far faster than ordinary flames, and engines that use them are a long-studied route to higher efficiency with fewer moving parts. A technology is placed here when the cited article describes a pulse or rotating detonation engine.
