The invention relates to a parafoil system suitable for rocket fairing landing area control and fixed-point landing. The parafoil system comprises a parachute shooting rocket used for shooting according to sequential control and pulling open a brake parachute assembly; the brake parachute assembly is used for a fairing brake parachute and used for first-stage speed reduction of a fairing half cover and stabilizing the posture of the fairing half cover. The parafoil assembly is used for performing secondary deceleration and realizing steering flight control until fixed-point landing is completed; the recovery and homing control device starts a parachute ejection time sequence at a preset height to control the parachute ejection rocket to eject, and pulls open the brake parachute assembly; the flight path data is received in real time to execute homing control and obstacle avoidance flight control, and a parafoil control rope control instruction is sent to the servo control device; the servo control device receives the parachute cord control instruction and controls the parafoil assembly, and steering flight control is achieved. According to the method, the uncontrolled landing area of the fairing is reduced by more than 80% by adopting a multi-target homing strategy, and landing area control, fixed-point landing and accurate recovery of the rocket fairing can be realized.

    本发明一种适用于火箭整流罩落区控制与定点着陆的翼伞系统,包括:射伞火箭用于按时序控制射出,并拉开减速伞组件;减速伞组件用于整流罩减速伞用于整流罩半罩的一级减速并稳定整流罩半罩的姿态;翼伞组件用于进行二级减速并实现转向飞行控制,直至完成定点着陆;回收与归航控制装置在预定高度启动弹伞时序控制射伞火箭射出,并拉开减速伞组件;实时接收航迹数据执行归航控制与避障飞行控制,发送翼伞操纵绳操控指令给伺服操纵装置;伺服操纵装置接收伞绳操控指令,对翼伞组件进行操纵,实现转向飞行控制。本发明采用多目标归航策略将整流罩无控落区面积减少80%以上,能够实现火箭整流罩的落区控制、定点着陆与精确回收。
