A deep optimization Algorithm for calculation of the flight trajectory of the launch vehicle

With the development of modern technology and application requirements, the launch platforms of the launch vehicle are gradually diversified and the flight trajectories are gradually complicated. The traditional basic calculation algorithms cannot meet the fast calculation requirements of the flight trajectories. Based on the traditional flight trajectory integration method and the classical Newton iteration algorithm, the iterative calculation time and calculation accuracy are optimized respectively, the adaptive optimal algorithm and the adaptive deviation increment algorithm are derived, a deep optimization algorithm for the calculation of the flight trajectory of launch vehicle is proposed. The simulation calculation and verification results show that the deep optimization algorithm can increase the average iterative calculation time to 1/40, that is, improve the calculation speed of the flight trajectory. At the same time, it can ensure the same accuracy as the traditional algorithm.
