Example Embodiment
[0021] Taking the first stage of a rocket as an example, the technical scheme of the present invention will be further described in detail with reference to the drawings and specific implementations. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work fall within the scope of the present invention.
[0022] 1. Establish a vertical return dynamic model of the rocket and consider constraints
[0023] After introducing the variable thrust factor, the three-degree-of-freedom dynamic model of the earth sphere model for the vertical return process of a child can be described by the following motion equation:
[0024]
[0025] In the formula: V is the flight speed; V x ,V y ,V z , X, y, z are the velocity and position components in the launch coordinate system respectively; θ is the...
