Problems solved by technology

However, the disadvantage of this solution is that due to the relatively high speed, a lot of energy will be consumed in the process of speed matching, which reduces the overall maneuverability of the spacecraft after docking
However, this method also has many limitations. For example, there will be many technical problems in the design of the buffer device. If the speed is too high, it may cause the energy conversion device to disintegrate or crash

Embodiment Construction

[0029] The present invention is described in further detail below in conjunction with accompanying drawing:

[0030] figure 1 It is a schematic diagram of the docking process between the gyroscopic device and the target spacecraft. In the process of rendezvous and docking of space spacecraft, the spacecraft with gyro device is regarded as the main body, and the spacecraft that needs to be docked is regarded as the target spacecraft 3 . The gyro device is used as the main part of the body for rendezvous and docking. The device is composed of a turntable 1 and a rope 2, wherein the turntable 1 can realize high-speed rotation; the rope 2 can be wound on the turntable 1, and a terminal of the rope is fixed on the turntable 1 ; Turntable 1 and rope 2 form the main body of the gyro-type device; 3 is the target spacecraft.

[0031] From figure 1 It can be seen that turntable 1 starts with The angular velocity is rotated, and the corresponding linear velocity v of the rope is r ...

Abstract

The invention discloses a device and method for gyroscopic type energy conversion for space docking. The energy conversion device can convert kinetic energy generated by a relative speed into rotating kinetic energy of the device through gyroscopic rotation when spacecrafts which have a large speed difference in space docking collide and are combined to be a whole, and thus this part of redundant energy is stored. The energy conversion process of the device is based on the mechanical energy conservation principle, it is guaranteed that the relative linear speeds of the two spacecrafts in rendezvous and docking in the space rendezvous and docking process are small enough, and the device and the method can be applied to rendezvous and docking tasks between the spacecrafts having large relative speeds.

Description

【Technical field】 [0001] The invention belongs to the field of aerospace technology, and in particular relates to a gyro-type energy conversion device and method for space docking. 【Background technique】 [0002] With the deepening of scientific research in the aerospace field, human scientific activities in space are becoming more diverse, and space development and applications are becoming more frequent. Space rendezvous and docking technology is the basis for spacecraft to complete space on-orbit operations. For more than half a century, mankind has completed complex space activities such as space station construction, long-term on-orbit residence, manned moon landing and deep space exploration based on rendezvous and docking technology, and has successfully carried out more than 300 manned or unmanned missions. Space rendezvous and docking tasks, it can be said that space rendezvous and docking technology has become a key issue in space exploration today and in the futur...
