DEVELOPMENT OF HIGH PERFORMANCE CAPABILITY CLASS AIRCRAFT TURBINE ENGINE OIL

As the key supporting material of engine, the main development direction of aviation turbine engine oil is better high temperature stability and high temperature coking resistance. According to the SAE AS5780D performance specification, the high performance RIPP 4058 aviation turbine engine oil（4058 lubricating oil） was developed. Starting with key raw materials, the research of new polyol ester base oil and amine high temperature antioxidant was completed successively. Then the formula was optimized to improve further its high temperature stability and high temperature coking resistance, which at the same time has excellent lubrication and physicochemical properties. The performance test data showed that the 4058 oil has excellent high temperature stability, lubrication performance, and physicochemical performance and is comparable with advanced foreign products. The process control system was established to ensure the performance and quality of 4058 lubricating oil.
