Summary:To provide a multiple pulse gas generating device that can stably burn a propellant.SOLUTION: A multiple pulse gas generating device 1 comprises a pressure container 2, a diaphragm 5, a first propellant 3, a second propellant 4, an ignition device 9, and an ignition gas injection device 8. The diaphragm 5 separates the first propellant 3 and the second propellant 4. The ignition device 9 generates ignition gas for igniting the second propellant 4. The ignition gas injection device 8 injects the generated ignition gas to the second propellant 4. The diaphragm 5 comprises a plurality of concave deformation parts 55 to be deformed in a concave shape by pressure of combustion gas of the second propellant 4 or the ignition gas, and a plurality of convex deformation parts 56 to be deformed in a convex shape by the pressure of the combustion gas of the second propellant 4 or the ignition gas. A flow rate of the ignition gas to be injected to the second propellant 4 provided outside one of the concave deformation parts 55 is higher than a flow rate of the ignition gas to be injected to the second propellant 4 provided outside one of the convex deformation parts 56.SELECTED DRAWING: Figure 1 【課題】推進薬を安定して燃焼できる複数パルスガス発生装置を提供する。【解決手段】複数パルスガス発生装置1は、圧力容器2と、隔膜5と、第1推進薬3と、第2推進薬4と、点火装置9と、着火ガス噴射装置8とを備える。隔膜5は、第1推進薬3と第2推進薬4とを分離する。点火装置9は第2推進薬4を着火する着火ガスを生成する。着火ガス噴射装置8は、生成された着火ガスを第2推進薬8に噴射する。隔膜5は、第2推進薬4の燃焼ガスまたは着火ガスの圧力により凹形状に変形されるべき複数の凹変形部55と、第2推進薬4の燃焼ガスまたは着火ガスの圧力により凸形状に変形されるべき複数の凸変形部56とを有する。1つの凹変形部55の外側に設けられた第2推進薬4に噴射される着火ガスの流量は、1つの凸変形部56の外側に設けられた第2推進薬4に噴射される着火ガスの流量よりも多い。【選択図】図1
