摘要:

为给先进直升机新型环境控制系统设计提供热输入边界条件,更准确有效的进行环控系统热管理与温度控制,开展了发动机滑油系统在宽飞行剖面下热载荷变化研究。首先,对发动机传动系统开展传动力学分析,建立发动机传动系统数学模型,分析发动机生热部件在各工况下的摩擦功耗,并进行简化完成摩擦损失理论计算;然后,以滑油温升为研究对象,分析引起滑油温度变化的生热以及散热部件影响程度,在此基础上采用Amesim建立发动机传动系统及滑油系统仿真模型,对滑油系统在宽飞行剖面下的热负荷变化进行了仿真分析;最后,将仿真结果与某型发动机滑油系统试验数据进行对比分析,表明系统模型满足工程设计要求,可对后续的环控系统热管理技术研究提供参考。

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 environmental 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 established 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.
