By setting the power generation device 104, energy loss is reduced, mechanical support is provided, the dynamic stability of the rocket is improved, and the orbital operation capability of the manned rocket is guaranteed. Therefore, it solves the technical problem that existing manned rockets will experience passive rotation due to the influence of natural forces such as airflow and gravity. While spin usually does not have a significant impact on the rocket's flight, it does affect the stability of the rocket's flight.

[0029] The inertial measurement unit 102 is used to measure the angular velocity and acceleration of the manned rocket and calculate its state. The navigation system 103 is connected to the inertial measurement unit 102 and is used to stably receive signals during navigation. The power generation unit 104 is connected to the navigation system 103 and is used to convert the wind resistance kinetic energy generated by the propeller rotation during rocket flight into electrical energy to power the navigation system 103 and provide equivalent kinetic energy to the rocket to counteract the gravitational drag during flight. The damper 105 is connected to the navigation system 103 and is used to change the rotational speed and direction of the stabilizing surface 101.

[0030] Secondly, there are four stabilizing surfaces 101. The four stabilizing surfaces 101 adopt a double-rotation structure, with two mounting angles deflecting in the same direction and the other two mounting angles deflecting in opposite directions.

[0039] The propeller is internally provided with the navigation receiver 108, and one navigation antenna 109 is mounted on the surface of each stabilizing wing surface 101, the navigation receiver 108 is used in cooperation with the navigation antenna 109, so that the navigation signal can be stably received, and then the received navigation signal is decoded and analyzed, so that the rocket can be positioned and navigated.
