低油耗和大推力是新一代发动机的追求目标,而由此也带来了发动机短舱内部温度过高的难题。本文通过对安装于短舱内部的发动机驱动泵与发动机短舱的热兼容性分析,发现发动机驱动泵密封圈无法满足发动机短舱内的热环境,并提出发动机驱动泵密封圈适应于高温环境的解决方案,为民机液压系统的工程应用提供指导。
Low fuel consumption and high thrust are the pursuit of a new generation of engines, which also brings the problem of excessive temperature inside the engine nacelle. Based on the thermal compatibility analysis of engine-driven pump and engine nacelle installed inside the nacelle, it is found that the engine-driven pump seal can not meet the thermal environment in the engine nacelle and the engine-driven pump seal is suitable for high temperature environment Solutions for civil aircraft hydraulic system engineering guidance.
