Rope net type space debris capturing and cleaning system

Abstract

The invention discloses a rope net type space debris capturing and cleaning system which comprises a transmission subsystem and a fly net subsystem. The transmission subsystem comprises a transmitter, a net cabin, a net cabin cover ejecting device, a buffer device, a tying rope tension control device and a tying rope cutter, and the fly net subsystem comprises a rope net and four mass blocks; a net cabin cover can be ejected out of an outlet of the net cabin, and the rope net can be driven by the net cabin cover to be drawn out of the net cabin; the transmitter works at the moment when the fly net and a tying rope are straightened, the sides of the rope net are driven by four mass blocks according to preset transmitting opening angles, so that the rope net can fly out and is opened simultaneously until the rope net is fully opened, an object is netted after the rope net reaches the objective position, a port of the rope net is tightened under the control of the mass bocks, and the object can be completely captured; after the tying rope draws the captured object aircraft away from an orbit, the tying rope cutter cuts off the tying rope, and the object aircraft can be separated from a satellite platform. The rope net type space debris capturing and cleaning system has the advantages that a secondary transmission mode is adopted, so that twining and knotting can be prevented in rope net spreading procedures; the mass blocks are pushed to be synchronously transmitted, so that a millisecond-level synchronous transmission effect can be realized, and the shape of the rope net can be controlled advantageously.

Description

technical field [0001] The invention relates to a rope net type space debris capture and removal system, which belongs to the field of aerospace technology and can be used for capture and cleaning of space debris (abandoned satellites, orbital garbage), and can also be used for the capture and on-orbit capture of other non-cooperative targets. Serve. Background technique [0002] Space debris originated from human spaceflight activities. With the rapid development of space technology, the number of space debris has also increased rapidly. According to the data released by the US Space Monitoring Network, as of January 2012, the number of space objects that can be monitored and recorded There are nearly 22,000 of them, more than 90% of which are space debris, and its potential collision risk increasingly threatens the safety of spacecraft in orbit, and has become an eye-catching environmental problem. At present, the mitigation measures for space debris in the world mainly i...

Problems solved by technology

The ROGER project gave the configuration of the launcher, and its launch system has the following deficiencies: (1) The four mass blocks adopt the method of spring ejection, which is difficult to accurately control the synchronization of launch, which may cause the center of the rope net to be biased and unable to wrap Objective; (3) Adopt the flying net deployment method of pulling out and unfolding at the same time. For large sparse rope nets, it is difficult to avoid the interference and penetration phenomenon between the net ropes during the deployment process of the flying net, resulting in knotting, entanglement, and failure to unfold smoothly.

The Furoshiki project is to use four angular satellites to expand the rope net (or film), which can expand a giant net with a width of several kilometers in space, but its capture system consists of four small satellites + rope net, the system is complicated and the cost is high , only suitable for capturing high-value important targets
