    • PROBLEM TO BE SOLVED: To provide a valve for a pulse detonation engine, in which high-speed opening/closing performance and metal fatigue/heat fatigue reducing performance are excellent, in which compactness, light weight, and long service life of a drive mechanism are achieved, in which an outlet of a combustor can be opened/closed at high speed, and in which mixed gas supply pressure to the combustor can be improved.
      SOLUTION: A cylinder rotation type supply valve 2, having a plurality of supply holes 7 provided in a part of a cylindrical surface symmetrically to a center axial line, and disposed at an inlet of the combustor is connected to a cylinder rotation type outlet valve 3 having a plurality of outlet holes 10 provided in a part of a cylindrical surface symmetrically to a center axial line, and disposed at an outlet of the combustor through a center shaft to be integrally driven to rotate. Combustion is repeated axially symmetrically at the same timing to reduce fatigue breakage due to pressure vibration. The outlet of the combustor is closed when fuel and oxidizer are charged to the combustor, thereby charging pressure is increased.
