Thermal load analysis for aeroengine oil system with extended flight profile
摘要
Abstract
In order to provide the heat input boundary conditions for the design of the new dual-system evaporation cycle subsystem of advanced helicopter and carry out the thermal management and temperature control of the environ-mental control system more accurately and effectively,the thermal load variation of the engine oil system under a wide flight profile was studied.First,the transmission mechanics of the engine drive system is analyzed,the mathematical model of the engine drive system is established,the friction power consumption of the engine heat generating parts under various working conditions is analyzed,and the theoretical calculation of friction loss is simplified.Then,taking oil temperature rise as the research object,the influence degree of heat generating and cooling components causing oil temperature change is analyzed.On this basis,simulation models of engine drive system and oil system are estab-lished by Amesim,and the heat load change of oil system under wide flight profile is simulated and analyzed.Finally,the experiment data and simulation results of a certain engine oil system are compared and analyzed.The results show that the system model meets the engineering design requirements and can provide reference for the subsequent thermal management technology research of environmental control system.关键词
