Embodiment Construction

[0036] The present invention will be described in further detail below in conjunction with the accompanying drawings, but this is only exemplary and not intended to limit the protection scope of the present invention. Below in conjunction with accompanying drawing, patent of the present invention is described further.

[0037] The core of the present invention is to use a large-area protective cover with a controllable inclination angle and a telescopic spring, reduce the vertical force on the protective cover by reducing the inclination angle, and increase the buffer time and buffer distance by using the telescopic spring. So as to achieve the purpose of decelerating and protecting space debris.

[0038] see figure 1 , figure 1 A schematic diagram of a typical Whipple structure mentioned in the present invention is given. Depend on figure 1 It can be seen that the traditional Whipple protective structure is a single-layer metal sheet (here the typical material is aluminum a...

Abstract

The invention discloses an umbrella space debris or a micrometeoroid protection device for a spacecraft. The device comprises an umbrella guard, a retractable spring and a controllable hinge. The umbrella protective cover is closely spliced into an umbrella structure by a plurality of triangular protective panels, and the inner side of each of the plates is connected with the controllable slidingcylinder disposed on the main support rod through the side support bars. With the impact of space debris or micrometeoroids, the umbrella shield can change the tilt direction of the shield along the sliding of the controllable slider on the main support bar to reduce impact damage. The device greatly reduces the direct force exerted by the space debris on the protective cover, increases the buffering time of the protective cover to the space debris, and improves the protection ability against the space debris, which is up to 40 times or more.

Description

technical field [0001] The invention belongs to the technical field of space debris and micrometeoroid environmental protection, and in particular relates to an umbrella-shaped space debris or micrometeoroid protection device for a spacecraft. Background technique [0002] "Space debris", also known as space junk, is the waste left in space by human spaceflight activities and is the main source of pollution in the space environment. Since the launch of the first artificial earth satellite in 1957, the total number of space debris has exceeded 40 million, and the total mass has reached several million kilograms. The number of space debris that can be observed by ground telescopes and radars has increased by about 200 per year on average, greater than 10 There are now more than 9,200 centimeters of space debris. Space debris is mainly distributed in the low-orbit region below 2000 kilometers, and they pose a serious threat to spacecraft in near-Earth space. [0003] The size...
