Embodiment Construction

[0013] Preferred embodiments of the present invention will be described below in conjunction with the accompanying drawings.

[0014] Accompanying drawing is the schematic diagram of the expansion control method of a kind of spacecraft inflatable film tube of the present invention, as shown in the embodiment of accompanying drawing, this method comprises the steps:

[0015] Step 1. Apply adhesive material inside the air-filled film tube.

[0016] Step 2. Flatten the film tube horizontally along the tube wall, curl and fold it on the curling roller; the tube wall of the inflatable film tube in the stored state is bonded together by the internal adhesive material.

[0017] Step 3, filling gas at one end of the film tube, the tube wall of the film tube presents a tensile stress, and forms a peeling area of ​​the upper and lower tube walls in the direction of expansion of the film tube. In this step, an obvious interface appears in the stripped area of ​​the tube wall of the film...

Abstract

The invention discloses a method for controlling the unfolding of an inflatable film tube of a spacecraft, comprising: 1. coating the interior of the inflatable film tube with viscous material; 2. flattening the film tube laterally along the tube wall, curling and folding it on a curling roller; 3. Fill one end of the film tube with gas to realize the full expansion of the inflatable film tube; 4. Set a restraint mechanism outside the expanded film tube for directional expansion or drive other auxiliary devices. The invention solves the problems in the prior art that the inside of the film unfolding structure cannot be completely evacuated and cannot be effectively controlled, and achieves beneficial effects such as light weight and easy control of unfolding speed.

Description

technical field [0001] The invention relates to a method for controlling the deployment of an inflatable structural film tube of an aerospace vehicle. Background technique [0002] Inflatable membrane structures for aerospace vehicles have the advantages of light weight, large shrinkage ratio, and large expanded size. Research institutions at home and abroad are competing to carry out research work in this field, and the deployment control and internal vacuuming of the inflatable membrane structure are difficult problems encountered in the development process. [0003] At present, due to the influence of residual gas caused by the inability to completely evacuate the interior of the inflatable structure, and the inability to effectively control the interior and other defects, the inflatable membrane structure verified by the track demonstration basically has no effective deployment control means. This makes the unfolding process of the inflatable film structure unpredictabl...
