Abstract
A three-axis attitude control propulsion device and a flying object like a rocket including the device are provided in which combustion gas for attitude control can be efficiently used. A three-axis attitude control propulsion device, having six nozzles has a motor caseand three-way discharge changeover valves' of a valve plug rotation type enabling a changeover of a flow passage by rotation of the valve plug. Combustion gasis generated by combustion of propellantin the motor case. The three-axis attitude control propulsion device is operated so that one or two of the nozzles are opened to thereby discharge the combustion gasand the remaining five or four nozzles are fully closed. Thereby, a three-axis attitude control of pitch control, roll control and yaw control, and control of a neutral state, can be selected.
