In order to ensure that the trajectory parameters of fighter meet the throwing conditions of unguided bomb, an attack path planning method of fighter is proposed. In this method, a fighter movement model is first established, and a basic tactical action model library is generated, and the action combinations are combined into basic trajectories; then, an open-closed-loop control model of the action parameters in each stage is constructed to microscopically control the tactical actions, and in light of pilot"s experience the constraint range of the parameter change is determined. Finally, based on the basic performance of unguided bombs and the tactical application methods, the throwing parameters of fighter are limited, and the trajectory planning is completed. The simulation result for the mobile jump and dive attack tactics shows that the planned track satisfies the attack conditions and the movement parameters meet the flight requirements, thus verifying the feasibility and effectiveness of the method.
