雨水对飞机发动机的影响

雨水对飞机发动机影响较大,当飞机在大雨中降落时,可能会引发发动机熄火,但在飞机起飞时,能起到喷水加力的效应.为了对发动机防吞雨水停车和喷水增大推力研究提供参考,综述了CFM56-3型发动机投入使用后出现的一些吞雨停车故障,并总结了在发动机设计中采取的尽量减少雨水流入内涵的4点措施,介绍了喷水增大推力的机理和其在一些军、民用飞机发动机上的应用情况.

Influence of Rain on Aeroengine

The influence of rain on aeroengine is evidence. During descend in heavy rain, sometimes aircraft power loss can occur due to flameout by ingesting a large amount of rain. In contrast, during aircraft take-off in heavy rain, aircraft performance will be improved as ingesting water to increase thrust. In order to provid reference for preventing engine shut down in gulping rain and increasing thrust through ingesting water, the engine shut down faults in gulping rain for CFM56 engine were reviewed. Four improvement measures of reducing rain flow into core engine were summarized. The principle of increasing thrust through injecting water and the applications in civil and military aircraft engine were introduced.
