Rocket fairing spinoff evaluation method

The present application belongs to the field of aerospace separation technology, and particularly relates to a rocket fairing rotating separation evaluation method. It aims to solve the problem of long cycle and high cost caused by the dependence of traditional fairing rotating separation scheme on high-fidelity simulation and physical test.

Then, the Runge-Kutta method is used to solve the mathematical model by cyclic iteration to obtain the motion trajectory parameters in the separation process. Finally, the separation motion trajectory is visualized based on the trajectory parameters, and the collision risk is evaluated by analyzing the relative position relationship between the trajectory and the rocket body. Based on the physical simplified model and numerical calculation method, the rapid and safe evaluation of the fairing separation process is realized, which greatly shortens the design verification cycle, and significantly reduces the evaluation cost due to the pure numerical calculation.
