According to the electronic delay secondary parachute opening landing device, the landing speed is preliminarily reduced by using a brake parachute, then a main parachute is opened, and the parachute opening dynamic load can be greatly reduced, so that the requirements for the strength of a rocket projectile and the strength of parachute structural parts are reduced, and the design difficulty and the production cost of the rocket projectile are reduced; a secondary parachute opening scheme is adopted, so that the staying time of remains in the air is shortened, and the processing difficulty is reduced; the electronic delayer is used for controlling the ignition time sequence of the rocket projectile, the whole process of rocket launching, sowing operation, brake parachute opening, main parachute opening and wreckage landing can be achieved, automatic operation is achieved, the delay precision is high, and the stability of the device is improved.

    本发明公开了一种电子延时二次开伞着陆装置,使用减速伞初步降低落速,再开启主降落伞,开伞动载可大幅降低,以降低火箭弹自身强度和降落伞结构件的强度要求,降低了火箭弹设计难度和生产成本;采用二次开伞方案,缩短残骸在空中停留的时间,降低处理难度;使用电子延时器控制火箭弹点火时序,可实现火箭发射,播撒作业,减速伞开伞,主降落伞开伞,残骸落地的整个过程,实现自动化作业,延时精度高,有利于提高装置稳定性。
