Abstract:

Aiming at the problem of gliding and extending the range of guided rockets, a solution with angle of attack as theoptimization variable was proposed in this paper. Based on the four-degree-of-freedom model of the rockets, the rocket-range optimization model was proposed based on the particle swarm optimization algorithm, and the constraints were estab?lished. The optimization simulation of a guided rocket trajectory show that the control of the angle of attack of the rocketcan effectively increase the range of the rocket. For the rocket gliding range problem, the angle of attack control methodproposed in this paper is feasible.
