穿过外涵机匣的管路结构设计

Structure Design for Pipeline through Bypass Casing

随着对航空发动机的引气、供油、点火、测试等功能要求的提高,穿过外涵机匣的传感器和管路数量大大增加,为降低外涵机匣拆装的难度,提高穿过外涵机匣的管路的可装配性,在原有管路的连接结构、密封结构、补偿结构、分解维护4个方面的结构设计基础上,设计了2种新型穿过外涵机匣的管路结构,新型管路具有结构简单、拆装便捷、安全可靠、互换性好等优点,可满足管路补偿和外涵机匣的密封要求。

The number of pipe and sensor through bypass casing is increasing with the improvement of the engine bleed air,fuel,ignition and other functional testing requirements.In order to reduce the difficulty of bypass casing assembly and improve the assemblability of the pipelines through the bypass casing,two new pipeline structure were designed based on the pipeline connecting structure,sealing structure,compensation structure and decomposition of maintenance.The new pipeline structure are simple and have good assembly and disassembly feature.The structure are safe and reliable,and have perfect interchangeability,which can meet the compensation and bypass casing sealing requirements.
