Self-stabilizing torque-free CubeSat brake sail de-orbit device

Abstract

The invention discloses a self-stabilizing torque-free CubeSat brake sail de-orbit device. The self-stabilizing torque-free CubeSat brake sail de-orbit device comprises a locking device, a storage mechanism, a mounting panel, a conical spring, a deployable mechanism and a polyimide film aluminized secondary surface mirror. The locking device is fixed to the top surface of the mounting panel, and the conical spring, the deployable mechanism and the polyimide film aluminized secondary surface mirror are all disposed in the storage mechanism. The self-stabilizing torque-free CubeSat brake sail de-orbit device is fixedly connected to the bottom of a satellite through the top mounting panel, and a whole brake sail de-orbit mechanism is located outside the satellite, so that no space inside thesatellite is occupied. After receiving a ground command, the locking device releases the deployable mechanism, the deployable mechanism pops out, and belt-shaped elastic masts drive the polyimide filmaluminized secondary surface mirror to deploy. The cross-sectional area of a CubeSat in the flight direction is increased by deploying the polyimide film aluminized secondary surface mirror, and theatmospheric resistance received by the CubeSat is improved, so that the rapid de-orbit of the CubeSat is accelerated. The self-stabilizing torque-free CubeSat brake sail de-orbit device is simple in structure and high in reliability, does not occupy the space inside the satellite, and has little dependence on a satellite platform.

Description

technical field [0001] The invention belongs to the field of spacecraft off-orbit, and in particular relates to a self-stabilizing non-torque cube star braking sail device. Background technique [0002] With the continuous development of aerospace technology, the number of spacecraft launched by various countries is increasing. Most of the spacecraft do not have their own off-orbit systems and continue to operate in orbit after completing their missions, resulting in an increasing number of space debris in Earth orbit. , the potential danger of becoming an effective on-orbit spacecraft, and it is not conducive to future human exploration of space. At present, human technology is still unable to effectively deorbit spacecraft that have failed to become space debris on a large scale. Therefore, equipping future spacecraft with deorbiting systems is the main measure to slow down the growth of space debris. The vast majority of space debris comes from artificial earth satellit...
