The helicopter hydraulic system has characteristics such as wide spreading,complicated structure and multifunction requirements,which make difficult to verity the hydraulic fluid temperature by experiment.The thermal model of typical helicopter hydraulic components was built.Aimed at a specific flight mission,the temperature variation of hydraulic system was simulated and analyzed.Comparisons between results with the flight data prove that the analysis method and the established models are correct and reliable,which can provide basis for design and optimization of helicopter hydraulic system.
