All spacecrafts for being sent to space all have it is limited the service life is actively used, after it enlivens the service life, space flight
Device and satellite become useless and accumulate in space, increase the amount of fragment.Unless they are removed or burn in an atmosphere,
Otherwise spacecraft and satellite are kept on its track, and with the increase of number of tiles, the collision between them is possibly realized
Cause to generate more fragments, and this phenomenon will also become increasingly prevalent.
Currently, there is several methods that the spacecraft derailing that life cycle can be made to terminate.The methodical purpose of institute is by near-earth
Point height is reduced to that air force is sufficiently large to reenter track to it, and the air force for being applied to spacecraft or satellite at this time adds
Heat and pressure will be sufficiently large, and spacecraft or satellite will be destroyed largely in an atmosphere.
Existing main derailing strategy includes using small rocket motor, and electronic tether or aerodynamic drag enhancing come
Pressure enters back into, then destroys target debris.
Small rocket engine can be used for pushing satellite to the earth at a particular angle and speed, to reenter
When ensure to destroy.Rocket engine can be used for reducing the speed of satellite, it is caused to fall and burn in an atmosphere.Rocket engine
Have benefited from using the missilery for having reached business level.The major advantage of rocket is to shoot to tear open to control by accurate angle
Unload process.However, rocketry is very expensive, very heavy, technical complexity, such as rocket fuel is before the use
It need to be up to 10 years under pressure.
Electronic tether is extended a distance between derailing spacecraft and the end mass of deployment, it is possible to public up to number
In, conductive strips below.Therefore tether technology is related to that the conductor wire from satellite is disposed and drawn by earth magnetic field.Tether and
Interaction between earth magnetic field generates propulsive force for raising and reducing satellite altitude track.In general, the portion of tether system
It will mostly in a dormant state during affixing one's name to the unit movable service life of the host spacecraft attached by it.When needing to derail, system
By deployment end quality to start derailment course.Electronic tether has potentiality, but in deployment and during derailment course itself
Need the active control of height.
Pneumatic towing enhancing is related with air drag increase.Air drag or towing with atmosphere height increase, atmosphere by
Gradual change is thin and reduces.This strategy of freeing is only limitted to low orbit satellite (LEO).Satellite in this region undergoes fairly limited gas
Dynamic resistance, and since air drag reduction causes satellite velocities also very small.The system that air force towing can be enhanced increases
Add air drag will enable satellite velocities reduced within the desired time.
In resistance enhancing system, towing sail is paid special attention to.Up to the present, the concept proposed includes by navigating
Its device is transported close to target debris position, and then compact towing sail is connected to target debris, finally expands to its final surface.
It is assumed that towing sail must be loaded into spacecraft in compact mode, and even if the packaging efficiency of towing sail is high, portable device
Quantity be also limited.
In view of future has a large amount of clasts to be removed, the mechanism that can manufacture resistance sail in space will be advantageous,
Various sizes of resistance sail mechanism can be especially manufactured, various sizes of derailing clast is allowed.In addition, will retain in space
And it can use raw material and necessary component to be refilled in space to manufacture the mechanism of resistance sail and will be advantageous.
In short, space manufacturing technology experienced fast development in the past few years.A large amount of new concepts and idea are suggested,
These concepts and idea essentially relate to the mechanism that a kind of structure and the necessary material of loading are established in space.These mechanisms are carried on
Beam is squeezed out on different directions, is combined together generation network by distinct methods again thereafter, and the space of network passes through
Different method panels or laminate covering.
Up to the present, the development of large scale structure, such as 8 solar panel of solar energy are concentrated on to the research of in-orbit space manufacture
The manufacture of array.Although manufacturing machine fixture has good prospect in big structure space, focus on to manufacture in space
And multiple smaller structures are discharged, such as resistance sail mechanism, it also will be meaningful.
