Abstract

The invention belongs to the field of spacecraft deorbiting, and particularly relates to a brake sail deorbiting device applied to a vertical satellite. The device includes: a sail storage device, a driving device, an unfolding device and a locking device which are sequentially arranged from top to bottom. A film sail is stored in the sail storage device; the unfolding device comprises four strip-shaped elastic masts and a mast center shaft, the extension sections of the strip-shaped elastic masts are connected with the film sail, and the fixed ends of the strip-shaped elastic masts are woundon the mast center shaft; the four wound strip-shaped elastic masts are unfolded to drive the thin film sail connected with the elastic masts to be unfolded; the driving device is used for driving thestrip-shaped elastic mast in the unfolding device to be unfolded; and the locking device is used for locking the unfolding device in a locking state. The deorbiting device provided by the invention is suitable for deorbiting cubesat running on medium and low orbits, and solves the problem that normal work of other satellites is affected by space debris due to the fact that part of cubesat cannotbe deorbited within a specified time after completing a task.

Description

technical field [0001] The invention belongs to the field of spacecraft de-orbiting, and in particular relates to a brake sail de-orbiting device applied to a satellite. Background technique [0002] CubeSat is a CubeSat standard jointly proposed by Caltech and Stanford University in 1999. It is a cube star with standardized volume and shape. The basic unit is a cube of 10cm×10cm×10cm. It is usually called a 1U cube star. After adding the corresponding number of units, it is also called a 2U cube star, 3U cube star, etc., with a simple structure. . [0003] CubeSat has gradually become a research hotspot at home and abroad due to its low cost, short development cycle, and high functional density. It can be seen that in the future, the number of CubeSat launches will grow in a "blowout" style. These cube satellites are usually distributed in low earth orbit. If they are not deorbited after completing their missions, these failed cube satellites will become space debris, res...
