Abstract

The work aims to investigate the underlying mechanisms behind the control failure of the oil cooling system in a specific aircraft model and then develop effective improvement and preventive measures to extend engine service life and prevent flight safety incidents. The layout of the control mechanisms and the aerodynamics of the cooling flaps in the oil cooling system were analyzed to identify the factors contributing to the control failure. Furthermore, through force analysis and modeling calculations of the cooling flaps, a rational optimization scheme was proposed. The replacement of materials could improve the wear resistance index of the transmission cables, thereby reducing the probability of jamming. Taking the cruise phase, where the control failure of the oil cooling system was most likely to occur, as an example, the corresponding values between the pilot's in-flight control force and the trailing edge angle adjustment of the cooling flaps were determined. Through multiple tests, the troubleshooting time for this issue was reduced by 2 hours. Optimizing the design of the cooling flap's trailing edge to resemble an aileron trim tab effectively reduces the troubleshooting time for this issue, thereby solidifying the foundation for equipment quality and safety.
