Braking sail derailment device for cube satellite

Abstract

The invention discloses a braking sail derailment device for a cube satellite. The braking sail derailment device comprises a locking device, a storage mechanism, a mounting panel, a conical spring, an unfolding mechanism and a diaphragm sail. The locking device is fixed on the top face of the mounting panel. The storage mechanism is fixed on the bottom face of the mounting panel. The conical spring, the unfolding mechanism and the diaphragm sail are arranged in the storage mechanism. The large-diameter end of the conical spring is fixedly connected with the mounting panel, and the small-diameter end of the conical spring is fixedly connected with the unfolding mechanism. The diaphragm sail is tied to the unfolding mechanism. The braking sail derailment device is fixedly connected to the bottom of the satellite through the mounting panel at the top, so that the space inside the satellite is not occupied. After receiving a command from the ground, the locking device releases a central shaft in the unfolding mechanism, and a strap elastic mast wound on the central shaft drives the diaphragm sail fixed on the mast to be unfolded by releasing elastic potential stored in the mast. According to the invention, the diaphragm sail is unfolded to increase the cross-sectional area in the flight direction of the cube satellite, and the atmospheric resistance of the cube satellite is increased, so that the cube satellite derails quickly.

Description

technical field [0001] The invention belongs to the field of spacecraft de-orbiting, and in particular relates to a cube satellite braking sail de-orbiting device. Background technique [0002] Space debris mainly includes man-made objects in near-Earth space other than active spacecraft. The space where they are produced and operated is generally in the area where most spacecraft currently fly. The main sources include rocket bodies, failed spacecraft, and mission-related objects. Fragments and Fragments. In recent years, with the continuous development of aerospace technology, the number of space debris in the earth's orbit has also been increasing, which seriously threatens the safety of effective spacecraft in orbit and also lays hidden dangers for the development of human space technology in the future. How to slow down the growth of space debris has become an urgent problem at home and abroad. The Inter-Agency Space Debris Coordination Committee (IADC) recommends tha...
