An expandable tapered membrane structure for space vehicle clearance

Abstract

The invention relates to an expandable tapered membrane structure used for space vehicle cleaning, and relates to the field of space vehicle passive protection and safety; it includes n support tubes, a windward resistance surface skin, m resin frames, gas cylinders and a fixed base; The fixed base is a positive n-pyramid structure; the bottom plane of the fixed base is fixedly installed on the external aircraft; each side of the fixed base is provided with an air outlet; the cone top of the fixed base is provided with an air inlet; each support tube One end of the axial direction is docked with one air outlet; the gas cylinder is vertically arranged on the top of the fixed base; the skin on the windward resistance surface is attached to the outer wall of n support tubes; m resin frames are evenly spaced on the skin on the windward resistance surface The inner surface of the space vehicle; the present invention carries out on-orbit deployment after the space vehicle reaches its service life, increases the area of ​​the windward resistance surface of the vehicle, increases the aerodynamic resistance suffered by the space vehicle, and realizes that the space vehicle reaching the service life of the low-earth orbit enters the atmosphere within 25 years Falling needs.

Description

A Deployable Conical Membrane Structure for Spacecraft Clearance technical field The invention belongs to the field of passive protection and safety of space vehicles, and relates to a Expand the conical membrane structure. Background technique [0002] The low-Earth orbit on the earth with a height of 200-800 km above the ground is the main space activity area of ​​human beings in the past sixty years. This area is filled with a large number of artificial satellites, rocket final stage thrusters and other aircraft. Most of the existing aircraft have a life span of 5 to 10 Years, the satellite that has reached its lifespan is out of control, because the spacecraft cannot achieve effective de-orbit after the mission and stay in the original orbit for a long time. Flying, it is very easy to collide with other space vehicles or space debris to explode and crack, forming a large number of new space debris, If no measures are taken, this potential domino effect will lead...

AI Technical Summary

Problems solved by technology

The active de-orbiting of a space vehicle is to reversely propel the aircraft in the form of propellant, reduce the speed of the aircraft, thereby lowering the orbital height of the aircraft, and finally realize the removal of the aircraft; the active de-orbiting method has the disadvantages of large mass, complex mechanism, and high cost
