航空润滑油4060的研制

DEVELOPMENT OF AVIATION LUBRICATING OIL 4060

根据活塞式航空发动机润滑要求,针对某合成烃航空润滑油使用中存在的积炭多、低温启动性差等问题,研制了15W50新型航空活塞式发动机润滑油——航空润滑油4060,研制油具有优异的油泥分散性能、腐蚀和氧化安定性、剪切安定性和优良的润滑性能以及材料相容性,各项性能满足GJB1219A—2009活塞式航空发动机润滑油产品规范。对研制油进行了生产工艺研究,产品批次稳定性良好。研制油先后通过了L38台架试验、发动机厂商的发动机长期试车考核试验,并成功完成实机试飞,在试飞中证实了航空润滑油4060具有良好的低温启动性能,且换油周期延长至原来的4倍。

According to the requirements of piston aeroengine and the problems such as more coke deposits and poor low temperature start-up performance,in use of the synthetic hydrocarbon aviation lubricating oil,a new type of lubricating oil-aviation lubricating oil 4060 was developed to meet the needs of the users.The developed oil had excellent sludge dispersibility,anti-corrosion and anti-oxidation stability,shear stability,excellent lubricating performance and material compatibility.All the performances met GJB 1219A-2009 specification for aircraft reciprocating engine(piston)oil.The production process of the developed oil was investigated,and the stability of batch product was good.The developed oil passed L38 bench test,300 h engine test and 600 h engine test,and had successfully completed the aircraft test flight.The test proved that aviation lubricating oil 4060 has very good cold starting performance ,and can extend the oil changing period to 4 times of that of before.
