タを冷却する機能を備えた固体ロケツトモータ。 A rocket motor combustion chamber, a propellant provided within the combustion chamber and generating combustion gas by combustion,
In a solid rocket motor equipped with a nozzle portion connected to the combustion gas generation port of the combustion chamber, the air intake port to the combustion chamber and the air intake port can be opened and closed, and after the combustion of the rocket motor is completed, the air intake port is closed. After the combustion of the rocket motor is completed, air is released from the air intake port by utilizing the pressure difference between the low pressure part of the dead zone that occurs near the nozzle exit and the atmospheric pressure when the flying object flies due to inertia. A solid-state rocket motor with a function that cools the rocket motor by drawing heat from inside the rocket motor and flowing air through the combustion chamber and nozzle.
