Autonomous Prediction of UAV Launch Parameters Based on SSA-BP Model

The coupling of key parameters such as launch angle, booster pinch angle, booster thrust, etc. affects the trajectory of the rocket boosted zero-length launch, and there exists a difficult problem of optimal selection of launch parameters. In this paper, a UAV is taken as the research object, dynamics and kinematics modeling of its launching stage is carried out, and parametric simulation software for UAV launching trajectory is designed based on QT/C++. Meanwhile, the UAV launch parameter prediction method based on SSA-BP model is proposed, and the superiority of SSA-BP for launch parameter prediction is comprehensively evaluated based on MAE, MAPE, and RMSE evaluation methods. The results show that the UAV launching trajectory simulation and launch parameter prediction model in this paper are effective and credible, and can provide a basis for the design of UAV launch system.
