摘　　要：橡胶管老化对气压测量装置功能的影响不可小视,对球载系统的安全运行构成巨大威胁。如何从多方面多措施防止橡胶管老化是需要考虑的一个关键性问题,文章从管道接头形式、橡胶管道路径优化、以及热设计三大方面综合改善了气压测量单元中橡胶管在使用过程中的材料物理状态和使用环境,使得气压测量装置的整体安全系数满足并超过了设计输入的技术标准要求。Rubber hose aging affects the function of device measuring air pressure can not be neglected. This is a huge threat to safe working of ballon-borne system. It is a key problem of how to prevent rubber hose from aging through different ways. Hose material physical state and use environmental of rubber hose in the air pressure measurement device were improved by hose tie-in forms, rubber hose＇s path optimizing and thermal design. These improvements enhanced safety factors of the air pressure measurement device and exceed the technical requirements of design input.
