| Abstract: | Debris generated by spacecraft breakup enters the atmosphere with ablation due to hypersonic aerodynamic heating.The survived fragments would pose great risks to the ground and people.This study aims at developing a debris reentry and ablation prediction system(DRAPS) for rapid prediction of spacecraft and debris reentry and ablation.A three degree of freedom(3DOF) ballistic model is used for predicting the spacecraft and debris trajectories.The Newtonian flow theory,collisionless molecular kinetic theory a... |
