Abstract
A kind of space vehicle controllable inflation launches hold-down arm inner bag, belong to developing space inflation hold-down arm technical field, solve at present when use more than two or two hold-down arms support an equipment, there is the speed difference that each hold-down arm launches, can not the problem of synchronous expansion, it comprises more piece thin film inner container, and more piece thin film inner container successively head and the tail is bonding, be provided with gas source pipe often saving thin film inner container inside, be provided with a gas source pipe inflation inlet often saving thin film inner container inside.The present invention is used for more than two or two space vehicle inflation synchronous expansion hold-down arms.
Description
Technical field
The invention belongs to developing space inflation hold-down arm technical field, be specifically related to a kind of space vehicle controllable inflation and launch hold-down arm inner bag.
Background technology
The inflating expanded hold-down arm of existing space vehicle is by attached resilient mounting bar and flexible skin outside a complete through thin film inner container, and be provided with thread gluing in outside, lightweight, can curlingly fold, the little aircraft of being convenient to of volume after folding carries, inflatable deployable when using in space, has good supporting capacity after expansion.At present when use more than two or two hold-down arms support an equipment, there is the speed that each hold-down arm launches different, can not the problem of synchronous expansion, very large on institute's fastening impact.
Summary of the invention
The object of the invention is to solve at present when use more than two or two hold-down arms support an equipment, there is the speed difference that each hold-down arm launches, can not the problem of synchronous expansion, provide a kind of space vehicle controllable inflation and launch hold-down arm inner bag, its technical scheme is as follows:
A kind of space vehicle controllable inflation launches hold-down arm inner bag, and it comprises more piece thin film inner container, and more piece thin film inner container successively head and the tail is bonding, is provided with gas source pipe often saving thin film inner container inside, is provided with a gas source pipe inflation inlet often saving thin film inner container inside.
Beneficial effect of the present invention is: can inflate to often saving in thin film inner container successively, and time delay can inflate in next joint thin film inner container after being full of a joint thin film inner container, realize launching in order, can synchronous expansion when the inflating expanded hold-down arm of the space vehicle that the many thin film inner containers provided by this programme are formed uses simultaneously.
accompanying drawing illustrates:
Fig. 1 is structural representation of the present invention;
Fig. 2 is the thin film inner container cut-away diagram of Fig. 1.
detailed description of the invention:
See figures.1.and.2, a kind of space vehicle controllable inflation launches hold-down arm inner bag, and it comprises more piece thin film inner container 1, and more piece thin film inner container 1 successively head and the tail is bonding, be provided with gas source pipe 2 often saving thin film inner container 1 inside, be provided with a gas source pipe inflation inlet 2-1 often saving thin film inner container 1 inside.
The quantity of described gas source pipe 2 is identical with the joint number of thin film inner container 1, all gas source pipes 2 penetrate into each joint thin film inner container 1 inside by the outer face of final section thin film inner container 1, and respectively a gas source pipe inflation inlet 2-1 being respectively set in each joint thin film inner container 1, the admission port 2-2 of all gas source pipes 2 is all arranged on outside the outer face of final section thin film inner container 1.
In order to make to be connected firmly between more piece thin film inner container 1, the junction of adjacent two joint thin film inner containers 1 is provided with reinforce belt 3, and it is bonding that reinforce belt 3 and adjacent two saves thin film inner container 1.
Gas source pipe 2 and the intersection of thin film inner container 1 are provided with seal ring 4.
All gas source pipes 2 are arranged as a row, and instant rolled complications are folded.
The length often saving thin film inner container 1 is set according to the total length of hold-down arm, the length of final section thin film inner container 1 is not more than the length of the curling folding rear outmost turns of hold-down arm, the length of other joint thin film inner container 1 is not more than the length of final section thin film inner container 1, first inflate in final section thin film inner container time inflating expanded, inflate one by one forward successively again after time delay, realize by relay and solenoid control.
