Lasso type space capturing device

Abstract

The invention discloses a lasso type space capturing device which comprises a support and a lasso capturing mechanism installed on the support, a rope fixing assembly in the lasso capturing mechanism enables the two ends of capturing ropes to be connected to an inner capturing ring and an outer fixing ring respectively, when the inner capturing ring rotates relative to the outer fixing ring, the multiple capturing ropes are folded inwards, the folded capturing ropes form a capturing rope loop, and when the diameter of the inscribed circle of the rope loop is not larger than the outer diameter of the target capturing object, the target capturing object can be captured. The device is particularly suitable for capturing an inverted-cone-shaped object and has large capturing tolerance, and the capturing reliability can be improved and the posture of the captured object can be corrected by using the two lasso capturing mechanisms which are axially installed in parallel to capture the object at the same time.

Description

technical field [0001] The invention belongs to the technical field of spacecraft capture, and in particular relates to a lasso-type space capture device. Background technique [0002] Space vehicle capture refers to the establishment of a mechanical connection relationship with the target vehicle already flying in space orbit through the capture mechanism of the mission vehicle, so that the attitude control and on-orbit operation of the target vehicle can be realized through the mission vehicle. Therefore, spacecraft capture technology is the premise and basis for realizing spacecraft de-orbiting, on-orbit service, and on-orbit maintenance operations. Currently commonly used space vehicle capture technologies include manipulator capture (CN200910073300.1), rope net capture (CN201310503724.3), and engine throat capture (CN201510789544.5). However, there are certain problems in these methods: the manipulator The capture method requires high operational precision and poor cap...

Problems solved by technology

Currently commonly used space vehicle capture technologies include manipulator capture (CN200910073300.1), rope net capture (CN201310503724.3), and engine throat capture (CN201510789544.5). However, there are certain problems in these methods: the manipulator The capture method requires high operational precision and poor capture tolerance, which requires the aircraft to have high attitude and orbit control accuracy; space flying net capture cannot be reused, the cost is high, and rigid connection cannot be established after capture; engine throat capture is only suitable for capture Engine nozzle, and may cause damage to the engine nozzle, which is not conducive to the subsequent use of the engine
