The invention relates to a vertical landing system and method for a manned spaceflight reentry capsule, and aims to improve the stability and safety of the reentry capsule in the landing process. The system comprises a reentry capsule main body, a large bearing device, a clamping groove mechanism, a lateral rotary spraying device, a sensor device and a control system. The reentry capsule body is composed of an inner body and an outer shell with a gap therebetween to mount a large bearing arrangement, supporting and allowing rotation of the outer shell relative to the inner body. The clamping groove mechanism is used for locking the relative position of the outer shell and the inner body when external rotation is not needed. The lateral rotary spraying device is installed on the periphery of the lower middle portion of the shell and sprays gas or liquid downwards in an inclined mode to enable the shell to rotate, and the reentry capsule is kept stable through the gyroscopic effect. The sensor device monitors the attitude, speed and height of the reentry capsule, and the control system calculates and controls an injection strategy according to data to realize stable vertical landing. By accurately controlling the injection and locking mechanism, the landing performance of the reentry capsule and the safety guarantee of astronauts are remarkably improved.
本发明涉及载人航天返回舱垂直着陆系统及方法,旨在提高返回舱着陆过程中的稳定性和安全性。该系统包括返回舱主体、大型轴承装置、卡槽机构、侧向旋转喷射装置、传感器装置以及控制系统。返回舱主体由内部体和外壳组成,二者之间设有空隙以安装大型轴承装置,支撑并允许外壳相对于内部体旋转。卡槽机构用于在无需外部旋转时锁定外壳与内部体的相对位置。侧向旋转喷射装置安装于外壳中下部四周,斜向下喷射气体或液体,使外壳旋转,利用陀螺效应保持返回舱稳定。传感器装置监测返回舱姿态、速度与高度,控制系统根据数据计算并控制喷射策略,实现稳定垂直着陆。本发明通过精确控制喷射和锁定机构,显著提升了返回舱的着陆性能和航天员的安全保障。
