Zusammenfassung:PROBLEM TO BE SOLVED: To restrict occurrence of oscillatory burning at a toroidal type igniter.SOLUTION: A first toroidal type igniter is a toroidal type igniter used at a solid rocket motor, comprising a toroidal-shaped combustion chamber for storing igniter powder, the combustion chamber has several injection ports for use in injecting combustion gas to the solid rocket motor, and the [2n+1] injection ports [n is an integer more than or equal to 1] are arranged under an equal spacing. A second toroidal type igniter is a toroidal type igniter used for the solid rocket motor, comprising a toroidal-shaped combustion chamber for storing igniter powder, the combustion chamber has several injection ports for use in injecting combustion gas to the solid rocket motor, and there are arranged the 2n injection ports in an unequal space [n is an integer more than or equal to 1].SELECTED DRAWING: Figure 1 【課題】トロイダル型点火器における振動燃焼の発生を抑制する。【解決手段】第1のトロイダル型点火器は、固体ロケットモータに用いられるトロイダル型点火器であって、点火薬を収納するトロイダル形状の燃焼室を備え、燃焼室が、固体ロケットモータに燃焼ガスを噴射するための複数の噴射口を有しており、噴射口が、等間隔で2n+1(nは1以上の整数を示す。)個配設されている。第2のトロイダル型点火器は、固体ロケットモータに用いられるトロイダル型点火器であって、点火薬を収納するトロイダル形状の燃焼室を備え、燃焼室が、固体ロケットモータに燃焼ガスを噴射するための複数の噴射口を有しており、噴射口が、不等間隔で2n(nは1以上の整数を示す。)個配設されている。【選択図】図1
