Abstract
The invention belongs to the technical field of space inflation unfolding supporting arms, and relates to an inner container for controllable inflation unfolding supporting arms of a spacecraft. The problems that when two or more supporting arms are used for supporting equipment at present, the unfolding speeds of the supporting arms are different, and the supporting arms cannot be unfolded synchronously are solved. The inner container comprises a plurality of film inner container sections, the film inner container sections are pasted sequentially end to end, an air source pipe is arranged in each film inner container section, and an air source inflation opening is formed in each film inner container section. The inner container is used for two or more inflation synchronous unfolding supporting arms of the spacecraft.
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 be by one completely connect thin film inner container outside attached resilient mounting bar and flexible skin, and be provided with thread gluing in outside, lightweight, can curlingly fold, volume after folding urine is carried in aircraft, inflatable deployable while use in space, has good supporting capacity after expansion.At present using more than two or two hold-down arm to support when an equipment, the speed difference that exists each hold-down arm to launch, problem that can not synchronous expansion is very large on institute's fastening impact.
Summary of the invention
The object of the invention is in order to solve at present in the time using more than two or two hold-down arm to support an equipment, the speed difference that exists each hold-down arm to launch, problem that can not synchronous expansion, provides a kind of space vehicle controllable inflation to launch hold-down arm inner bag, and its technical scheme is as follows:
A kind of space vehicle controllable inflation is launched 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 in every joint thin film inner container inside, is provided with a gas source pipe inflation inlet in every joint thin film inner container inside.
Beneficial effect of the present invention is: can in every joint thin film inner container, inflate successively, and can in next joint thin film inner container, inflate being full of after a joint thin film inner container time delay, realize in order and launching, can synchronous expansion when the inflating expanded hold-down arm of space vehicle that the many thin film inner containers that provided by this programme are formed uses simultaneously.
brief description of the drawings:
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 is launched 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 in every joint thin film inner container 1 inside, be provided with a gas source pipe inflation inlet 2-1 in every joint 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 at each, joint thin film inner container 1 is interior that a gas source pipe inflation inlet 2-1 is respectively set respectively, the admission port 2-2 of all gas source pipes 2 is all arranged on the outer face outside of final section thin film inner container 1.
In order to make to be connected firmly between more piece thin film inner container 1, be provided with reinforce belt 3 in the junction of adjacent two joint thin film inner containers 1, reinforce belt 3 is bonding with two adjacent joint thin film inner containers 1.
Be provided with seal ring 4 in gas source pipe 2 and the intersection of thin film inner container 1.
All gas source pipes 2 are arranged as a row, and instant rolled complications are folded.
The length of every joint 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, when inflating expanded, first in final section thin film inner container, inflate, after time delay, inflation one by one forward successively again, can realize by relay and solenoid control.
