The invention relates to the technical field of spaceflight, discloses a safe landing system for N-stage rocket recovery, and aims to overcome defects that fire explosion hidden dangers exist in an existing rocket vertical recovery technology, and second-stage and even N-stage rockets cannot be conveniently recovered, so safe landing of the rockets is reliably realized when the rockets are recovered on an offshore platform and a land platform. The system comprises a base, a controllable lifting stand column, a lifting annular platform, a GPS satellite tracking positioner, a microcomputer and the like. According to the system, a landing mode of landing legs of an original rocket is changed, functions of landing, buffering, standing and the like of the rocket are replaced by the lifting receiving mechanism, the supporting mechanism, the buffering damping mechanism and the like arranged in the embodiment, a problem of fire and explosion caused by hidden dangers of non-straight standing, unstable standing and poor standing when a traditional rocket is recovered and landed can be solved, under the condition that other processes of rocket recovery are normal, the goal of safe home and repeated use of a hundred percent N-grade rocket in a short time can be achieved.
本发明涉及航天技术领域,针对现有火箭垂直回收技术存在的火灾爆炸隐患,及不能便捷的回收2级乃至N级火箭的弊端,公开一种N级火箭回收的安全着陆系统,确保火箭在海上平台、陆地平台回收时,可靠实现安全着陆。系统包括基座、可控升降立柱、托举环型平台、GPS卫星跟踪定位器、微机等;本实施例改变了原火箭“着陆腿”的着陆方式,其着陆、缓冲、站立等功能,由本实施例设置的托举接收、支扶、缓冲减震等机构替代,可解决传统火箭回收着陆时,由于“立不直,站不稳”、“差一点”的隐患所导致火灾爆炸问题,在火箭回收其他几个流程都正常的情况下,可实现百分之百的N级火箭“安全回家”、短时间内重复使用的目标。
