Cylinder 12.
The present invention is applied to single star and separates or many stars networking separation scheme, to introduce this with reference to two application examples
Bright operation principle and process.
【Application example one】Single star separation scheme
Satellite and the rocket attachment means are connected with satellite stripper 1, after rocket enters the track of predetermined release satellite, the satellite and the rocket
Attachment means unlock, and the first stepper motor 3 and the second stepper motor 10 start simultaneously, now with reference to Fig. 2, the first stepper motor 3
Driving the first flexible rack 4 that turns clockwise moves, and the synchronous rotate counterclockwise of the second stepper motor 10 drives the second flexible rack 9
Motion, according to pre-set constant power, under the restriction of sleeve 12, the first flexible rack 4 and the second flexible rack 9 promote satellite jointly
Stripper 1 moves (direction as shown is not necessarily actual direction) upwards, provides for satellite and separates initial velocity, away from rocket end
Level, realizes the satellite and the rocket and separates.
【Application example two】Multi satellite separation scheme
Taking double star series arrangement as a example, satellite and the rocket attachment means two satellites of independent connection.During first satellite unblock, second
Satellite is still within lock-out state.After first satellite separation release finishes, rocket continues to second with second satellite
The predetermined launching trajectory of satellite advances, and during this period, the first stepper motor 3 and the second stepper motor 10 invert simultaneously, drives
First flexible rack 4 and the second flexible rack 9 reset, and pull satellite stripper 1 counter motion playback (as Fig. 1).Enter the
After the predetermined launching trajectory of two satellites, second satellite unlocks, and the first stepper motor 3 and the second stepper motor 10 rotate forward again
Start, the first stepper motor 3 turns clockwise and drives the first flexible rack 4 to move, the second stepper motor 10 is synchronous to be revolved counterclockwise
Turn and drive the second flexible rack 9 to move, according to pre-set constant power, under the restriction of sleeve 12, the first flexible rack 4 and second is soft
Property tooth bar 9 promotes satellite stripper 1 to move (direction as shown is not necessarily actual direction) upwards jointly, is that second satellite carries
For separating initial velocity, away from final vehicle, realize the satellite and the rocket and separate, finally realize double star transmitting.Many star transmittings are with this in the same manner.
Refer to Fig. 3, be the schematic diagram of second embodiment of the invention first guide rail, the second guide rail and the first guide rail structure pair
Claim therefore omit.Second embodiment and the form of the composition differring primarily in that guide rail and stop part of first embodiment.In this enforcement
In example, the first guide rail 2 includes rail 22 in the first outer rail 21 and first, and the first stop part 5 is to bypass the first stepper motor 3 by outer rail
Output shaft after back extend formed, the first flexible rack 4 is between the output shaft of the first outer rail 21 and the first stepper motor 3
Engage with the output shaft tooth of the first stepper motor 3;Second guide rail 11 includes rail in the second outer rail (not shown) and second (does not scheme
Show), the second stop part 8 is back to extend after the output shaft being bypassed the second stepper motor 10 by the second outer rail to be formed, and second is soft
Property tooth bar 9 is engaged with the output shaft tooth of the second stepper motor 10 between the output shaft of the second outer rail and the second stepper motor 10.
It is arranged such and can ensure that tooth bar is more reliable and more stable with the cooperation of the output shaft tooth of stepper motor.
In the present embodiment, in the first stop part 5 and first, the distance between rail 22 is less than the first flexible rack 4 and first
Overall size on this range direction for the limiting section 6;In second stop part 8 and second, the distance between rail is less than the second flexible rack
9 and second overall size on this range direction for the limiting section 7.It is arranged such and can avoid limiting section between stop part and interior rail
Abjection, when repeating to push away satellite, can preferably ensure that be driven stablizes and effective.
In other embodiments (not shown), sleeve 12 can also be to be converged by the first guide rail 2 and the second guide rail 11 to be formed,
I.e. sleeve 12 and guide rail are integrally formed, and with reference to the arrangement form of second embodiment middle guide, sleeve 12 can also be by outside first
The head end of rail and the second outer rail cooperatively forms.It is arranged such and be conducive to integration processing.
The present invention is not only limited to above-mentioned specific embodiment, and persons skilled in the art are according to disclosed by the invention interior
Hold, the present invention can be implemented using other multiple specific embodiments, therefore, the design structure of every employing present invention and think of
Road, does some simple designs changing or changing, both falls within the scope of protection of the invention.
