The invention relates to the technical field of aircraft power systems, and discloses a barrel type launching miniature fuel gas generator and a barrel type launching device.The barrel type launching miniature fuel gas generator comprises a shell, a main charging column, an igniter and an easily-broken part, a containing cavity is formed in the shell, the shell is provided with a first end wall, and a first vent hole communicated with the containing cavity is formed in the first end wall; the main charging column is limited in the containing cavity, and a through groove extending in the axial direction of the shell is formed in the main charging column. The igniter comprises an explosive blocking shell and an ignition tube, part of the explosive blocking shell is located in the through groove, the breakable piece is arranged between the first end wall and one end of the explosive blocking shell in a sealed mode so as to seal the first vent hole and enable the containing cavity to be a sealed cavity, and the ignition tube is limited in the explosive blocking shell; and a power line of the ignition tube penetrates through the explosive blocking shell and the first end wall in a sealed mode to be connected with an external power source, the ignition tube is used for igniting the main charging column so as to generate fuel gas, and the fuel gas can break through the easily-broken part and then rushes out of the shell from the first vent hole. And the total envelope size is small.
本发明涉及飞行器动力系统技术领域,公开一种筒式发射用微型燃气发生器及筒式发射装置,包括外壳、主装药柱、点火器和易破件,外壳内具有容纳腔,外壳具有第一端壁,第一端壁上开设有与容纳腔连通的第一通气孔,主装药柱限位在容纳腔内,主装药柱内形成有沿外壳的轴向延伸的通槽;点火器包括挡药壳体和发火管,挡药壳体的部分位于通槽内,易破件密封设置在第一端壁和挡药壳体的一端之间,以封闭第一通气孔,并使容纳腔为密封腔,发火管限位在挡药壳体内,且发火管的通电线密封穿过挡药壳体和第一端壁与外部电源连接,发火管用于引燃所述主装药柱,以产生燃气,燃气能冲破易破件后从所述第一通气孔冲出至外壳外。总包络尺寸较小。
