燃气涡轮航空发动机与发动机油规格

Aircraft Turbine Engine and the Specification of Engine Oil

概述了航空发动机发展历程与现代航空发动机的发展现状。介绍了现代航空发动机油的规格发展,以及对航空发动机润滑油性能的主要要求。通过分析,指出了目前国际上主要的航空发动机油规格仍然以美国军标规格为主导;提出了我国自主研究开发航空发动机油,需要重点考虑油品在高低温条件下的贮存稳定性、氧化安定性和腐蚀性,同时需要同步研制开发满足现代航空发动机油所需求的新戊基多元醇酯型合成基础油。

The developed course of aircraft engine and the developing actuality of modern aircraft engine are summarized. The development of modern aircraft engine oil specification and the main demands on the properties of aircraft engine oil are introduced. By analysis, it is pointed out that MIL specification is still now the dominant of aircraft engine oil specification internationally. Moreover, for the independent R＆D of aircraft engine oil in China, it is necessary to consider mainly the storage stability at high ＆ low temperature, oxidation stability and corrosiveness; At the same time, the R＆D of neopentyl polyol ester type synthetic base oil to meet modern aircraft engine oil is also needed.
