【Abstract】 Based on the research of working principle of the helicopter oil cooling system and its main components, a steady-state simulation model of multi-factor coupling is established, including temperature, pressure and flow. A simulation software is developed with VC++ 6.0. Utilizing the simulation software and the calculation results, resistance characteristics of the oil system and key parameters are analyzed in order to determine the main components and main factors that impact the resistance characteristics of oil system, which are lubricating oil pump, filter, radiator, nozzle and oil temperature, flight altitude respectively. On the basis of analysis, system resistance characteristics under different flight conditions and altitudes are predicted, which also provide a reference for the components selection and the optimal design of the oil system.更多还原
