A satellite derotation device using vortex spring

Abstract

The invention provides a satellite rotation eliminating device using a scroll winding mechanism. The scroll winding mechanism is installed in a scroll winding mechanism box. The central starting point of the scroll winding mechanism is fixedly connected with a rotating shaft, and the tail end point of the scroll winding mechanism is fixedly connected with a shell. One end of the rotating shaft is connected with a fixing piece bearing at the top end of an in-orbit operation mechanical arm and provided with a holding locking device, and the other end of the rotating shaft is in pin joint with a base of a satellite capturing platform and provided with a holding locking device and an annular speed sensor. The satellite rotation eliminating device using the scroll winding mechanism is simple in structure, light in weight and high in reliability; when the satellite rotation eliminating device using the scroll winding mechanism works, rotation of a target satellite is eliminated during capturing the target satellite without energy consumption.

Problems solved by technology

[0003] At the same time, with the continuous development of human spaceflight technology, the number of artificial spacecraft operating in orbit is also increasing. The design life of artificial spacecraft is limited, the quality of fuel carried is limited by the carrying capacity, and some parts are still damaged and invalidated at any time. Or the possibility of upgrading and refitting is required. Due to cost considerations, maintenance, refueling and refitting of cooperative spacecraft in orbit have become a problem that must be faced in the aerospace field today.

[0004] For the consideration of rigid body dynamics, most spacecraft operating in orbit adopt spin stabilization system or dual spin stabilization system, that is, the spacecraft has a rotational angular velocity around the spin axis, which has a great impact on the spacecraft’s on-orbit operation. come difficult

The previous idea was to offset the spin angular velocity of the spacecraft through the consumption of electric energy by the motor to generate reverse torque, which has the disadvantages of large mass and power consumption, which brings difficulties to the structural design and mass arrangement of satellites operating in orbit
