Abstract:
1. A pulse detonation engine for detonating a gaseous mixture of an oxidizer and a fuel in a combustor to obtain thrust, comprising: a supply valve able to open and close provided in the inlet of said combustor; and an exit valve able to open and close provided in the outlet of said combustor, wherein said supply valve is rotationally driven to open the inlet of said combustor and said exit valve is rotationally driven to close the outlet while said gaseous mixture is supplied to the combustor; and wherein said exit valve is rotationally driven to close the outlet of said combustor and said supply valve is rotationally driven to close the inlet while said gaseous mixture is ignited and a combustion occurs with a detonation wave propagated in the combustor; and wherein said exit valve is rotationally driven to open the outlet of said combustor and said supply valve is rotationally driven to close the inlet when said detonation wave of said combustion reaches the outlet of the combustor.
