Description
Art
Adsorption device is grabbed the present invention relates to a kind of space, and in particular to a kind of space non-cooperative target attachment machine instantaneously triggered
Structure, belongs to space technology field.
Background technology
Space non-cooperative target is that a class does not have special docking to capture mouth or actively can not be carried in itself to pursuit spacecraft
For the spatial movement body of the communication information, such as failure spacecraft, the discarded satellite of failure and space junk.Space non-cooperative target
Docking capture technique has huge development prospect and application value on military and civilian.In military affairs, the current each space flight in the world
Big country is devoted to the correlative studys such as development space art of attack and defense, seriously threatens the space safety of China, and China must be energetically
Development space noncooperative target docks capture technique, sets up to possess and forces the Space Attack technology of capture enemy's spacecraft ability to be put down
Platform；On civilian, noncooperative target docks capture technique in the in-orbit filling and maintenance to failure spacecraft, and the discarded satellite of failure is returned
Receive, there is important Research Significance and value in the task such as removing of space trash fragment.
The noncooperative target docking capture technique studied at present can be divided into three classes：The first kind utilizes pair of mechanical arm+cone-bar
Acquisition mode is connect, noncooperative target privileged sites (apogee kick motor jet pipe) are implemented to arrest, capture process is complicated, control
System requires higher, it is necessary to fine measurement to end；Equations of The Second Kind is flexible winged pawl, the docking acquisition mode of flying mesh：Fly pawl capture
Mode：Object is equally the privileged sites such as satellite and the rocket separation ring of noncooperative target, solar array support etc., and control requires higher,
Docking operation is complicated；The mode of flying mesh capture：When target enters in the coverage of flexible flying mesh capture operation, flying mesh is ejected,
Open and envelope locking target.This mode is easily influenceed by noncooperative target profile, and easily object construction is damaged；The
Three classes are noncooperative target surface attachment mode, mainly including Electrostatic Absorption, electromagnetic adsorption, cementing (cold glue or pressure sensitive adhesion
Agent), pressure difference absorption, bionical absorption (class gecko dry absorption), this several typical surface attachment mode of the comparative analysis of table 1.
Traditional contact adhesive (double faced adhesive tape etc.), cold glue are influenceed larger by space temperature, volatile debindered effect；Sucker
Absorption is difficult to realize in vacuum environment；Electromagnetic adsorption requires that absorption surface must be magnetic conduction face, and need more energy with
And more complicated control；Electrostatic Absorption requires that noncooperative target surfacing is powered, and this mode absorption affinity is smaller and in high-tension electricity
Easily occurs point discharge off field；Bionical adsorption entails absorption surface is smooth or semi smooth, and absorption affinity is small, easily comes off.
The content of the invention
