Through the long-term test of the aero engine reliability on ground bench, we check and assess the new anti-corrosion synthetic aero lubricant.During the testing process, the parameters of the engine lubrication system is monitored and analyzed real-time.We accumulate and analyze the changing data about the lubricant performance.All the results show that the newly developed product has excellent anti-oxidation at high temperature, as well as anti-wear and lubricating performance, corrosion inhibition and anti-foam performance.And it also has excellent long-term storage stability and service performance.
