FG-86 solid rocket motor is a conventional solid rocket motor developed by Beijing Institute of Power Machinery. It consists of front head, combustion chamber, nozzle and igniter. The engine adopts head ignition technology. After ignition, the charge continues to burn and generate rated thrust, and then the aircraft falls off freely under the action of aerodynamic force and gravity when it reaches the specified speed. It can be used as the first stage take-off power device of UAV and missile
