Abstract
An end burning type gas generator includes a hollow cylindrical combustor, a propellant that is densely charged in the combustor concentrically and in a plurality of layers without leaving a large void in an internal cross section and that has the same sectional area in each of the layers, and an interstructure separating the plurality of layers from each other and connecting only at a turning portion at an axial end. The propellant end burns sequentially, progressing via the turning portion, beginning with an outermost layer or an innermost layer. The turning portion includes an end outer plate continuously surrounding ends of inner propellant and outer propellant, and a burning rate increasing member provided along the inner surface of the end outer plate to increase the burning rate of the propellant. The end outer plate is shaped such that the burning area at the turning portion remains substantially constant.
