Structure system capable of achieving double-point hanging conversion and separation for parachute

Abstract

A structure system capable of achieving double-point hanging conversion and separation for a parachute includes a connection and separation mechanism (4), hanging slings (3), main parachute separationdevices (2), and dampers (1). Through reasonable configuration with a drag parachute cluster parachute system and a main parachute cluster parachute system, and under driving of an initiating explosive device, connection and separation of a drag parachute can be completed in a normal working mode, a main parachute bag is pulled out, connection and hanging conversion of a main parachute cluster parachute are performed, a heat-proof layer is pulled off, impact overload of the hanging conversion is reduced, and unlocking separation of the main parachute cluster parachute is completed; in addition, self-adaption of a work mode of single drag parachute failure of the drag parachute cluster parachute system can also be completed; under judgment of a control program, work modes of landing on water and ground are selected by the initiating explosive device; and a redundant unlocking device for the drag parachute enables the reliability to be improved. The system has the characteristics of large carrying capacity, multiple work modes, high reliability, and the like, and can be widely applied to occasions of connection and separation of cluster parachutes.

Description

technical field [0001] The invention relates to a structural system capable of realizing double-point hanging conversion and separation of parachutes, and belongs to the design field of spacecraft return deceleration and landing. Background technique [0002] With the further development of manned spaceflight technology, my country has broken through and mastered the manned space rendezvous and docking technology, and has begun to move towards the era of independent construction of space stations. At the same time, the United States, Russia and other countries are stepping up the development of a new generation of manned spacecraft with stronger functions and performance, aiming at various fields such as space station services, manned deep space exploration, and deep space residence. ability to fly. To this end, our country must also develop a new generation of manned spacecraft with independent intellectual property rights. [0003] The new generation of manned spacecraft...

AI Technical Summary

Problems solved by technology

The connection and separation mechanism used by the Shenzhou spacecraft is no longer suitable for the connection and separation functions of the multi-stage group parachute system due to the change of the load and the use conditions of the group parachute.

At the same time, the overload of the steel wire rope used by the Shenzhou spacecraft to carry the main parachute from a single point of force to a double point of force (this process is referred to as: hanging conversion) is no longer suitable for the reason of design difficulty and installation layout. For the use of a new generation of manned spacecraft
