PROBLEM TO BE SOLVED: To provide a multi-pulse gas generator which can increase the number of pulses with a compact structure.SOLUTION: A multi-pulse gas generator comprises: a cylindrical pressure vessel; a cylindrical outside propellant which is disposed in the pressure vessel; a cylindrical intermediate propellant which is disposed inside the outside propellant; a cylindrical inside propellant which is disposed inside the intermediate propellant; an internal structure which is disposed inside the inside propellant, and fixed to the pressure vessel; a first diaphragm which partitions the outside propellant and the intermediate propellant; and a second diaphragm which partitions the intermediate propellant and the inside propellant. The outside propellant is supported to the pressure vessel at its external face, and the inside propellant is supported to the internal structure at its internal face. 【課題】コンパクトな構造でパルス数を増加させることができる、マルチパルスガスジェネレータを提供すること。【解決手段】マルチパルスガスジェネレータは、筒状の圧力容器と、圧力容器内に配置され、筒状である外側推進薬と、外側推進薬の内側に配置され、筒状である中間推進薬と、中間推進薬の内側に配置され、筒状である内側推進薬と、内側推進薬の内側に配置され、前記圧力容器に対して固定される、内部構造体と、外側推進薬と前記中間推進薬とを隔てる第１隔膜と、中間推進薬と前記内側推進薬とを隔てる第２隔膜とを備える。外側推進薬は、外面で、前記圧力容器に支持されており、内側推進薬は、内面で、前記内部構造体に支持されている。【選択図】図１
