A three-dimensional linkage tethered satellite

Abstract

The invention discloses a stereoscopic coordinated type tethered subsatellite. According to the novel tethered subsatellite, a limited power mechanism and an electromagnetic control switching mechanism are utilized for achieving independent or coordinated recycling and releasing of multiple salve satellites under the condition that a master satellite does not spin, and needed space and mass are compressed. By controlling the running number of circles of a motor, all sub-satellites are unfolded according to a preset scheme, and interfering angular momentum generated by motor rotation is offsetthrough the symmetric layout. Multiple traction ropes are adopted for replacing a traditional thought of a single traction rope, and transverse swinging of the tethered subsatellite in the unfolding and recycling process is restrained. By means of double-layer spring pop-up mechanisms, the release initial velocity of the needed angle is provided for the salve satellites, and kinetic energy is stored and buffered in the recycling process.

Description

technical field [0001] The invention relates to a radiating tethered satellite, in particular to a method of fixing one or more satellites on a main spacecraft by ropes or chains, which can be launched and recovered at any time, so as to accomplish some tasks that conventional single spacecraft cannot complete. Special spacecraft for the mission. Background technique [0002] A spacecraft (Spacecraft) refers to an aircraft that performs specific tasks in space (space) outside the earth's atmosphere to explore, develop and utilize space and celestial bodies other than the earth, also known as space vehicles. Satellites are currently the most important spacecraft for human exploration, development and utilization of space, including various scientific satellites, technology test satellites and application satellites. [0003] Satellite formation flight is widely used. The individual design of multiple satellites with separate functions is less difficult, and the formation of...

Problems solved by technology

However, the current spin deployment scheme requires strict cooperation between the release of the slave star and the rotation of the master star, which requires high precision for the control system, and it is difficult to suppress the spin of the slave star pulled by a single tether along the direction of the tether. More power mechanisms will increase the mass burden of the master star, and the control difficulty of the control system will also increase when the number of slave stars increases
