Description
Technical field
It leaves the right or normal track technical field the invention belongs to LEO, and in particular to a kind of inflation for passively leaving the right or normal track increases resistance ball.
Background technique
Currently be directed to LEO leave the right or normal track means and the problems of it is as follows:
(1) removal technology is arrested in space towboat pursuit, and this kind of technology is more mature, and controllability is high, but reusability is poor,
Remove higher cost, about 27,000,000 dollars/；
(2) rope system leaves the right or normal track technology, spacecraft with tether together orbital motion, tether constantly cut earth magnetic field and in tether
Both ends generate electromotive force, thus the resistance by earth's magnetic field leaves the right or normal track and reenters atmosphere.The disadvantage is that tether is easily cut off by space junk,
The risk to collide with other spacecrafts is also increased, and limited to some polar orbiting satellite effects；
(3) braking sail leaves the right or normal track technology, stretches film by support mast on satellite and forms sail, increases defending in directional velocity
Star sectional area forces satellite to leave the right or normal track to increase atmospheric drag, and this method that leaves the right or normal track needs accurate gesture stability, and leave the right or normal track effect
Rate is unstable；
(4) expanded foam increases resistance technology, and electrostatic force increases resistance technology, and dust increases resistance technology, mainly for small-sized fragment, by broken
Piece spray foam or plasma or dust etc. increase the area-mass ratio of fragment, increase the atmospheric drag of fragment, but technology Shang Bucheng
It is ripe, and the particle cloud and mist retained may influence the spacecraft operated normally.
Summary of the invention
The purpose of the present invention is to solve the problems that leaves the right or normal track of LEO, provide a kind of inflation for passively leaving the right or normal track
Increase resistance ball, its technical solution is as follows:
A kind of inflation increasing resistance ball for passively leaving the right or normal track, it includes covering and the inflation/deflation interface being arranged on covering, and covering is adopted
It is less than or equal to 5 μm of polyimide film material with thickness.
Using this material sphere empty gas after folding volume it is minimum, it is inflating expanded after global density it is minimum,
Gathering can be folded to deliver in the space of very little, minimal amount of gas energy is filled on the LEO close to vacuum environment
Expansion is unfolded and keeps certain aerodynamic configuration, air drag and solar light pressure that can be faint with Collection utilization after expansion, reduces empty
Between fragment the speed of service, to reduce its flying height until destroying by fire into atmosphere；It empties gas and the inflation folded increases resistance
Ball can be encapsulated in a cuboid box, and an end face of cuboid box is set as hinge-lid, and hinge-lid passes through
The locking of priming system bolt；It is used if be fixed on other satellites, ventilating control system can be set on other satellites,
After other satellites are scrapped, ventilating control system control priming system bolt pops, and sphere is inflating expanded, at present inflation control
System technology matures processed can directly utilize the prior art, when there is no signal to be passed to such as more than one week or miscellaneous stipulations time,
It can not receive heartbeat instruction, then assert that satellite fails, ventilating control system excitation priming system bolt pops, to make hinge-lid
Expansion, then ventilating control system opens gas cylinder slowly inflating expanded increasing resistance ball again, starts to leave the right or normal track；Or in cuboid box
Integrated ventilating control system, constitutes the cube satellite that leaves the right or normal track an of complete function, realizes modularization, applies in the outer surface of box
Glue, can carry the box of multiple complete functions using satellite or other aircraft, and pursuit approaches after space junk
Module is adhered on space junk by mechanical arm etc., ventilating control system can start to work；The glue can use
Cliftone adhesive, transliteration are that Cray not pauses adhesive, are bought by Shanghai world pharmaceuticals from the U.S., space environment adapts to
Property it is good, adhesive is uniformly applied to adhesive face, smearing thickness 1mm solidifies after 48 hours, show soft elasticity, be similar to rubber
Glue can adhere to immediately after contacting metal, easy to use；The inflation of 4m diameter increases resistance ball, and covering uses 5 μm of thickness of ultra-thin polyamides
Imines film, quality is less than 400g；Since aeration quantity is small, the quality of ventilating control system is less than 250g；Cuboid box is adopted
With carbon fibre material, quality is less than 150g；Reserved quality 200g, gross mass can control within 1000g, and total volume is
The volume of cuboid box is not more than 1 cubic decimeter, is very easy to delivery；Camera, GPS etc. can also be installed in remaining space
Optional equipment；The increasing that 4 meters of diameter hinders ball, can make to leave the right or normal track in space junk 1 year of the 120kg of 600km orbit altitude and destroy by fire,
Or the space junk of 1700kg leaves the right or normal track and destroys by fire for 25 years, meets the world and leaves the right or normal track time limit requirement；It can be according to orbit altitude, fragment matter
The time limit of measuring and leave the right or normal track calculates the satellite modules parameter of needs.
Following table is according to the calculated Common Parameters of space junk status:
Ventilating control system generally uses nitrogen for charge air conditioning, the source of nitrogen can there are two types of, one is carry high pressure gas
Bottle, another kind are generated by chemical reaction, and prior art automatic control easy to accomplish is utilized.
Covering by muti-piece warp direction cut-parts heat seal bonding forming；By taking 1.8m diameter sphere as an example, using with a thickness of 5 μm
Kapton production, be covering by the cut-parts bonding of 12 pieces of warp directions.
After cutter determines cut-parts, the Kapton by being coated with FEP coating is bonded as connection sheet come heat seal,
Kapton has the effect of warp enhancing as connection sheet, similar to the reinforcement inside lantern, sphere can be enhanced and exist
D type ability of the LEO by small atmospheric drag；The weight gain of cut-parts connecting portion is lower than 15g/m2。
A method of it manufacturing above-mentioned inflation and increases resistance ball, it is minimum to be able to achieve the weight gain of cut-parts connecting portion, is lower than 15g/m2, and
It can guarantee intensity, it is comprised the steps of:
One, taking width is the connection sheet of 4-10mm, sprays FEP solution in a side surface of connection sheet using spray gun, FEP is fluorinated
Ethylene propylene copolymer, wherein the content of hexafluoropropene is 10-20%, and coating thickness is 3-10 μm；The thickness of connection sheet and cut-parts
It is identical；
Two, the connection sheet for spraying FEP solution is heated in three stages, first heats 2-3min in the environment for being preheated to 150 DEG C, so
230 DEG C of reheating 2-3min are warming up in 5 min afterwards, 330 DEG C of reheating 2-3min are finally warming up in 5 min；
Three, on the surface of spraying FEP solution that two panels cut-parts are butted up against to the connection sheet after heating, then hot pressing connects are carried out, heat
Pressing temperature is 300-350 DEG C, hot pressing pressure 20-100kpa, hot pressing time 10-30s.
The invention has the benefit that creative proposition utilizes on the ground the not ball of the ultra-thin super large of application value
Body is unfolded to play in LEO increases resistance effect, has good application value；The weight that inflation increases resistance ball is extremely light, collapses volume
Minimum, delivery is convenient, is easy to modularization use, can be left the right or normal track using faint air drag and solar light pressure, additional without consumption
Energy does not need gesture stability omnidirectional and increases resistance.
