摘要：
Aimed at the reentry guidance problem for hypersonic deformable vehicle, firstly, a shaping plan of hypersonic deformable vehicle using telescopic wings is proposed, and the aerodynamic model and dynamic model with elongation deformation are established. Secondly, with the elongation deformation being extended to control variables, the relationships between bank angle, elongation deformation and terminal range, altitude are analyzed. On this basis, the remaining range and terminal altitude are predicted by bank angle and elongation deformation, the two control variables are corrected by numerical algorithm to meet the range and altitude constraints, and the bank angle symbol is determined through the heading angle corridor. Simulated results show that the reentry guidance method of the deformable vehicle has high guidance accuracy, having stronger terminal restraint ability and smoother trajectory compared with the fixedshape vehicle, and it has certain robustness under disturbance conditions. © 2021, Editorial Board of JBUAA.
