The invention provides a child-mother configuration satellite group with an inter-satellite unlocking and separating device and an installation method, the child-mother configuration satellite group comprises a connecting and unlocking assembly and a separating push rod assembly, the connecting and unlocking assembly is used for keeping or releasing rigid constraint between a mother satellite and a child satellite, and the separating push rod assembly is used for separating the mother satellite and the child satellite; the separation nut limiting seat sleeve is mounted on the mother satellite structural plate or the secondary star structural plate, and the separation part seat sleeve is mounted on the child satellite structural plate or the mother satellite structural plate; the push rod sleeve is installed on the mother satellite structural plate or the child satellite structural plate, the end, penetrating out of the push rod sleeve, of the sliding rod abuts against the child satellite structural plate or the mother satellite structural plate, and the separation spring is in a compressed state. Rigid connection of the mother satellite and the child satellite at the injection stage of the satellite is realized, and the mechanical environment adaptability of the child satellite is improved; the detonation separation nut is detonated, unlocking of the mother satellite and the childsatellite is achieved, the impact reduction pad assembly is beneficial to weakening detonation impact, transmitted to the child satellite, of the detonation separation nut, and the requirements for low impact, light weight and flexibility are met.
本发明提供了一种具有星间解锁分离装置的子母构型卫星组及安装方法,包括连接解锁组件和分离推杆组件,连接解锁组件用于保持或解除母星和子星间的刚性约束,所述分离推杆组件用于分离母星和子星;分离螺母限位座套安装在母星结构板上或子星结构板上,分离部座套安装在子星结构板上或母星结构板上;推杆套筒安装在母星结构板上或子星结构板上,滑杆穿出推杆套筒的一端抵紧子星结构板或母星结构板,分离弹簧处于压缩状态。实现了卫星入轨阶段母星和子星的刚性连接,有助于提高子星的力学环境适应性;火工分离螺母起爆,实现母星和子星的解锁,减冲垫组件,有助于减弱传递到子星的火工分离螺母的起爆冲击,且满足了低冲击、轻量化、灵活化的要求。
