This paper describes one of new concepts on application of detonation waves to the engine systems. The detonation wave is a combustion wave which propagates with a supersonic speed and a steep pressure rise. In normal engine systems, such as the spark ignition engine and the gas turbine, the detonation phenomena should not occurred because their steep pressure rise. But, in principle, the detonation can short a combustion time to a minimum. The decrease of the combustion time increases a thermal efficiency. Examples which are developed as detonation engines are a Scram-Jet engine, a Ram Accelerator and a Pulse Detonation Engine (PDE). The present article describes the PDE which are developed recently, and which utilizes the propagating detonation wave through a chamber.
