Abstract

A folding and unfolding method of an inflatable reentry deceleration flexible unfolding structure belongs to the technical field of spacecraft reentry, return and landing. The invention relates to providing an efficient and reasonable folding and unfolding method for an inflatable reentry deceleration flexible unfolding structure. Mainly through compression and folding, the flexible unfolding structure is folded inside the vehicle during launch and before re-entry deceleration; the connection and fixation with the vehicle is simple, and the packet unlocking is reliable; it can be unfolded in an orderly manner during re-entry deceleration to ensure the normal operation of the flexible deployment structure. The invention adopts the folding packaging method, which can effectively reduce the volume of the inflatable reentry deceleration flexible deployment structure in the spacecraft, simplify the connection and unlocking form, and at the same time ensure the orderly deployment of the flexible deployment structure, which has high application value.

Description

technical field

[0001] The invention relates to a folding and unfolding method of an inflatable reentry deceleration flexible unfolding structure, which belongs to the technical field of spacecraft reentry, return and landing. Background technique

[0002] In order to improve the means and capabilities of space vehicle reentry and return, and extend the application field of human spaceflight activities. Advanced space reentry deceleration structures suitable for new situations and new technology requirements must be developed. The inflatable reentry deceleration flexible deployment structure is one of the important light-weight space structures with great application prospects.

[0003] The inflatable reentry deceleration flexible deployment structure is wrapped by a folded high-temperature-resistant flexible braid around the payload compartment, which is folded and shrunk into a small volume during launch. After launching into orbit, it relies on its own internal gas The ...
