以某型飞机机翼防冰系统为研究对象,基于Flowmaster软件建立管路仿真模型,对不同工况下防冰系统管路的引气流量、笛形管射流孔出口流速、温度与压力分布进行分析,并在此基础上提出防冰系统管路的优化方案。分析结果表明:机翼防冰系统不同缝翼段内直径不同的笛形管可通过设置不同的射流孔孔径以优化防冰系统管路。 Based on an anti-icing system of a certain aircraft wing, a flow simulation model was set up based on Flowmaster software. The air flow rate, the outlet flow velocity, the temperature and the pressure distribution of anti-icing system piping under different operating conditions Analysis, and on this basis proposed anti-icing system pipeline optimization program. The analysis results show that the different shapes of the flutes in different wing sections of the wing anti-icing system can optimize the anti-icing system piping by setting different orifice diameters.
