Igniter fixing support and solid rocket engine

The utility model provides an igniter fixing support and a solid rocket engine. The igniter fixing support comprises a guide connecting part used for being connected with the inner molded surface of a spray pipe, an igniter bonding bin used for being fixedly connected with an igniter and an ignition wire passing hole used for allowing an ignition wire to penetrate through. The guide connecting part is connected with the igniter bonding bin; the igniter bonding bin is provided with a cavity for accommodating an igniter; and the ignition wire passing hole is communicated with the cavity. The machining difficulty of the spray pipe is reduced, the molded surface structure of the spray pipe is prevented from being damaged, the heat insulation layer structure of the spray pipe is prevented from being changed, and flowing of gas in the spray pipe is prevented from being affected. 本申请提供一种点火器固定支架及固体火箭发动机，点火器固定支架包括：用于与喷管内型面连接的导向连接部、用于固定连接点火器的点火器粘接仓和用于穿过点火线的点火线过线孔；导向连接部与点火器粘接仓连接；点火器粘接仓具有容置点火器的空腔；点火线过线孔与空腔连通。本申请降低喷管的加工难度
