Space flying net launching device and launching method

Abstract

The invention discloses a space flying net launching device and method. The device comprises an outer cylinder, an inner cylinder and a space flying net. The outer cylinder is provided with a first cavity and a first launching port, and the inner cylinder is detachably arranged in the first cavity through an inner cylinder launching mechanism; and the inner cylinder is provided with a second cavity and a second launching opening, the space flying net is contained in the second cavity, and the inner cylinder is provided with a flying net launching mechanism connected with the space flying net. By means of the two-stage launching mode, the defect that a traditional ejection mode cannot give consideration to the launching distance and the effective time is overcome, decoupling of two indexes is achieved, the launching distance and the effective time are both improved, and the performance of the flying net capturing device is improved; and secondly, since the two-stage emission mode realizes decoupling of the emission distance and the effective time, the parameters can be respectively considered and adjusted to change the emission distance and adjust the second-stage emission parameter to change the effective time during parameter design, and the efficiency of design work is improved.

Description

technical field [0001] The invention relates to the technical field of space capture, in particular to a space flying net launching device and a launching method. Background technique [0002] The Space Flying Net is a device used to clean up space junk. Such as figure 1 As shown, after the capture satellite maneuvers to the vicinity of the target, the ejection tractor will take the net out and fly to the target. After the net collides with the target, it will wrap around the target and capture the target. In the traditional launch mode, the launch device is fixed on the parent star, such as figure 2 shown. The process in which the tractor takes the net out of the parent star and unfolds in space is called the launch of the space flying net. The time period from the initial moment of ejection to the moment when the flying net expands to the maximum area is called the launch time, and the flight distance of the center of the flying net within the launch time is called th...

Problems solved by technology

[0004] Aiming at the problem of negative correlation coupling between the launch distance and the effective distance in the above-mentioned prior art, the present invention provides a space flying net launch device and a launch method. By designing a two-stage launch mode of the space fly net, the launch distance and the effective distance are eliminated. Negative correlation coupling between them, while improving the two indicators of launch distance and effective time
