specific Embodiment approach 1

[0019] Specific implementation mode 1: In this implementation mode, gecko glue is used to realize the docking between tiny spacecraft, and the specific steps are as follows:

[0020] A layer of gecko glue containing nano-cilia is used to fix a layer on the surface of the flexible deployment device. The array direction of the gecko glue is outward, and the primary array of the gecko glue is distributed on the surface of the flexible deployment device. secondary array. After the flexible deployment device is deployed, when it comes into contact with the docking target, the gecko glue is bonded based on the intermolecular attraction, and the target spacecraft can be bonded together. When the spacecraft needs to be separated, the gecko glue can be easily peeled off from the surface of the spacecraft.

[0021] In this embodiment, the gecko glue uses the hydrogen bubble template method to prepare porous metal as a template, pours a high polymer, and takes out the template for prepa...

specific Embodiment approach 2

[0036] Embodiment 2: This embodiment differs from Embodiment 1 in that the butt joint is achieved by coating the surface of the flexible deployment device with a pressure-sensitive adhesive.

[0037] For the convenience of operation, the pressure-sensitive adhesive can be sealed into the microreactor (the microreactor is spherical, its size is 2-200 μm, and the thickness of the capsule wall is 10-20 μm), so that it does not have viscosity and the device is easy to store. Storing the flexible deployment device airtightly in the launch cabin of the spacecraft in a folded form ( Figure 5 ), after entering the predetermined track, open the airtight device, and stretch out the folded flexible deployment device ( Figure 6 ), exposed to vacuum, the microreactor ruptures, and the pressure-sensitive adhesive flows out, achieving bonding to the target ( Figure 7 ).

[0038] In this embodiment, the pressure-sensitive adhesive may be selected from, for example, acrylate pressure-sens...

specific Embodiment approach 3

[0040] Specific embodiment 3: The difference between this embodiment and specific embodiments 1 and 2 is that the reactive docking device is folded and stored airtightly in two spacecraft launch cabins that need to be docked at the same time during launch ( Figure 8 ).

Abstract

The invention discloses a multiple repeated butt joint method of a spacecraft space, and relates to a micro spacecraft space butt joint method. The multiple-repeated butt joint method of the spacecraft space comprises the following steps of: coating a pressure-sensitive adhesive or gecko glue on the surface of a flexible unfolding device; then storing the flexible unfolding device closely in a spacecraft launching cabin in a folded mode when launching is implemented; opening an airtight device after the flexible unfolding device enters a predetermined orbit, stretching out the folded flexible unfolding device, and meanwhile unfolding slowly; and bonding the flexible unfolding device with a target spacecraft through the pressure-sensitive adhesive or the gecko glue when the flexible unfolding device touches another spacecraft. According to the multiple-repeated butt joint method, the flying speed and butt joint force are buffered by adopting the flexible slow unfolding device; two spacecrafts are bonded and connected integrally by adopting the pressure-sensitive adhesive or the gecko glue when in space orbit; the spacecrafts are separated away conveniently by peeling off from surfaces of the spacecrafts, and the spacecrafts are in butt joint and are separated; and the butting-joint flexibility, reliability and success ratio of the spacecrafts can be improved, and the difficulty of the butt joint mode is lowered.

Description

technical field [0001] The invention relates to a space docking method of a tiny spacecraft. Background technique [0002] Space rendezvous and docking is an extremely complex space operation performed by two or more spacecraft in space. Space rendezvous and docking is a very complex and difficult technology in the current world aerospace field, and various spaceflight countries are constantly investing a lot of manpower, material and financial resources in active exploration and research. [0003] At present, the main docking method is mechanical docking. Through the coordination of orbital parameters, two or more spacecraft can reach the same position in space at the same time, and then connect them as a whole through a special docking mechanism. However, the two spacecraft must reach the same position in space at the same time under high-speed flight, and there is a risk of collision if they make mistakes. Therefore, space rendezvous and docking is a very complex and di...
