Embodiment Construction

[0024] The invention provides a fast and controllable inflation release mechanism, which is mainly composed of five parts such as an end cover, a gas generator, a guide cylinder, a film tube and a sticky buckle. This mechanism mainly unfolds the folded film tube through the gas generated by the gas generator. Its working process is as follows. When it needs to be deployed, an electrical signal is sent to the gas generator from the outside. Under the action of the electrical signal, the gas-generating agent in the gas generator is detonated, and a large amount of gas is generated instantaneously. The gas first enters the guide cylinder. The other end of the guide tube has a small air outlet, such as Figure 5 As shown, the gas flows out through the air outlet and directly acts on the expansion end of the inflatable tube. Under the action of air pressure, the inflatable tube expands outwards along the guide tube in sequence. The expansion process is as follows: Figure 6 shown....

Abstract

The invention relates to a rapidly-controlled aeration releasing mechanism which mainly comprises an end cap, a gas generator, a guide cylinder, a thin film tube and a thread gluing and the like, wherein the gas generated by the gas generator ensures the folded thin film tube to be unfolded. The rapidly-controlled aeration releasing mechanism provided by the invention has the characteristics of light weight, small volume, rapid unfolding process and controllability, thereby providing an effective method for realizing the requirement of rapid releasing structures in the aerospace field and relative fields.

Description

technical field [0001] The invention relates to a fast and controllable inflation release mechanism applied in the field of aerospace. Background technique [0002] Due to the limitation of the effective launch load and launch volume of the launch vehicle, the requirement for the carried payload is to have a small weight and a small launch volume. Large-scale space structures are in a folded state when launched, and after being launched into orbit, they are unfolded to form the state required by their design and realize their design functions. Most of the existing unfolded structures are unfolded mechanically, which not only has high weight, but also has low folding efficiency. Contents of the invention [0003] The technical characteristics of the present invention are: the structure is mainly constructed of film materials, and the structure is light in weight; since it is mainly made of film materials, the structure can be folded in a folding manner, and the present inv...
