Space-debris-and-projectile stopping protection device and system

Abstract

The invention discloses a space-debris-and-projectile stopping protection system. The space-debris-and-projectile stopping protection system comprises a space-debris-and-projectile stopping protectiondevice and an inflation device, and the inflation device is used for inflating an inflation pipe of the space-debris-and-projectile stopping protection device; the space-debris-and-projectile stopping protection device comprises a front screen, a middle screen, a back screen and the inflation pipe; the front screen, the middle screen and the back screen are made from basalt fiber cloth and aramidfiber cloth, and are connected with the inflation pipe; the front screen, the middle screen and the back screen are unfolded after the inflation pipe carries out inflation. According to the space-debris-and-projectile stopping protection system, the flexible unfolding stopping protection device is adopted, the occupied volume weight of an aircraft is small, the system can be flexibly unfolded andapplied as required, and can also be matched with the working process of a flexible unfolding cabin to achieve the unfolding protection function, and the application requirement of space-debris-and-projectile protection is met.

Description

technical field [0001] The invention relates to a space debris and projectile arresting protection device and system, belonging to the field of passive protection and safety of space vehicles. Background technique [0002] In order to improve the safety and survivability of spacecraft, it is necessary to increase the collision protection capability of spacecraft to resist the collision of space debris and projectiles. At present, high-value space vehicles such as satellites, spacecraft, and space stations are basically equipped with debris and projectile collision protection structures. [0003] The current space vehicle collision protection technology is still based on the traditional Whipple rigid protection structure technology. The Whipple protection configuration is the most basic form of the space debris and projectile protection scheme. The Whipple protection structure is composed of two layers of aluminum alloy protective screens. The back of the screen is partiall...

AI Technical Summary

Problems solved by technology

[0004] The disadvantage of the rigid protective structure is that it takes up a lot of space and weight, and the installation position on the aircraft is fixed, so it cannot be flexibly configured

In addition, for space structures such as flexible inflatable pressure chambers in large spaces, they are folded and packaged during launch, and inflated and unfolded after entering orbit, so rigid protective structures cannot be used.
