End burning type gas generator

An end burning type gas generator comprising:

• (a) a hollow cylindrical combustor;
• (b) a first propellant densely charged in the combustor concentrically in a plurality of layers without leaving a large void in an internal cross section thereof, wherein the sectional area of each layer is equal, and wherein the plurality of layers include an inner layer, an intermediate layer, and an outer layer;
• and
• (c) an interstructure that separates the plurality of layers from each other and that connects the inner layer and the outer layer of the plurality of layers only at a turning portion on an axial end of the end burning type gas generator, wherein the turning portion comprises
• i. an end outer plate continuously surrounding ends of the inner layer and the outer layer;
• and
• ii. a burning rate increasing member provided along an inner surface of the end outer plate to increase the burning rate of the first propellant, and where the end outer plate is shaped so that a burning area at the turning portion remains substantially constant;
• wherein the first propellant sequentially burns at an end from the outer layer or the inner layer via the turning portion.
