Abstract: Satellite needs to be able to unsealing and resealing at any time in the factory building without civil reconstruction,and the environment of storage conditions could be controlled.This article proposes a solution based on flexible storage methods,in view of storage requirements and related standards.According to the standard,a flexible storage system is designed,which mainly includes a variable support frame,a flexible sealing film and a monitoring system.We carry out mechanical and electrical design and finite element simulation calculation of structural strength of the supporting frame;research,analysis and test verification of the sealing performance,strength performance,and different gas permeability of the flexible sealing film;the software and hardware design of the storage environment monitoring system.Part of the specific design is carried out to realize the real-time monitoring and storage of temperature,humidity,pressure,cleanliness,nitrogen concentration and other parameters in the storage environment and the analysis of environmental data.Each part of the entire system adopts a modular design,the size of the space can be adjusted,and the configuration of monitoring sensors can be increased or decreased according to requirements.Different modules can be freely transplanted between systems to achieve generalization.Through the implementation of the storage solution based on the flexible storage system,the long-term flexible storage of the entire satellite under the controllable environment is realized for the first time.
