Embodiment Construction

[0057] The present invention will be described in detail below with reference to the drawings and specific embodiments.

[0058] Combine Figure 1-2 The structure and working principle of the Cubestar brake sail wire burning mechanism of the present invention are as follows:

[0059] The brake sail wire burning mechanism includes a mounting panel 2, a strong horse wire 7, a pressing rod 8, a rotating shaft 12, a tension spring 14, and a separation switch 23. One end of the pressing rod 8 is rotatably connected with the rotating shaft 12, the rotating shaft 12 is fixed on the mounting panel 2 by screws, and the other end is fixedly connected to one end of the tension spring 14, and the other end of the tension spring 14 is fixed on the mounting panel 2. The tension spring 14 It is not on the same straight line as the pressure rod 8. In the compressed state, the pressing rods 8 of the two sub-mechanisms are parallel to each other, and the separation switch 23 is disconnected. The di...

Abstract

The invention discloses a power supply and control circuit applied to a CubeSat brake sail. The power supply and control circuit comprises a power supply circuit and a control circuit, wherein the front end of the power supply circuit is connected with a solar cell array specially provided by a CubeSat for the brake sail, wherein the solar cell array is converted into a busbar voltage after passing through a super capacitor charging circuit, and meanwhile a super capacitor module is charged; the busbar voltage is converted into 3.3 V voltage after passing through a 3.3 V converter, so that power is supplied to chips in a wire burning circuit and the control circuit, wherein the wire burning circuit burns out a Dyneema wire fixing a fixing device with a busbar and releases the brake sail under the control of the control circuit, and meanwhile provides feedback of an unfolding state of the brake sail for the control circuit; and the control circuit communicates with an on-satellite computer through a 422 bus and reports the status of the brake sail to a ground station. The power supply and control circuit can work independently from a satellite platform, and even if a satellite fails, the brake sail can be unfolded at a preset unfolding time, so that the satellite off-orbit process is accelerated.

Description

Technical field [0001] The invention relates to the field of spacecraft off-orbit control, in particular to a power supply and control circuit applied to the cubic star brake sail. Background technique [0002] In recent years, with the rapid development of communications, optoelectronic components, materials, sensors, and other technologies, CubeSats with low cost and high functional density have gradually emerged, which greatly reduces the development cost and development cycle of satellites. Remote measurement and testing have gradually become a trend. [0003] In recent years, more and more cubic stars have been launched by various countries. Most of the cubic stars do not have their own de-orbiting system, and the design life of the cubic stars is generally only 1-3 years, and it takes at least 10 years to de-orbit slowly under natural conditions. , Resulting in an increasing number of space junk in the earth's orbit, becoming a potential hazard for effective orbiting spacecr...
