摘　　要：为满足国产航空发动机小流量进气防冰试验的需求,基于结冰风洞的发动机进气模拟系统,分析了典型小流量发动机进气部件的进气特征,开展了小流量发动机进气模拟方法研究。提出采用水环真空泵解决了大流阻进气导致吸气管道压力大幅度降低问题,在此基础上,优化了发动机进气模拟系统,建立了在结冰风洞开展小流量发动机进气部件防冰试验的流程,并应用于某型号小流量发动机进气部件防冰试验。结果表明:发动机进气模拟系统满足小流量发动机进气部件防冰试验要求,进气流量控制精度达到±0.05 kg/s(±0.33%FS),试验过程中的流量变化可用于辨别防冰效果。相关研究为发动机进气模拟系统设计、优化和小流量发动机进气部件的防冰特性考核提供了参考依据。In order to meet the requirements of low-flow intake anti-icing test of domestic aeroengines,based on the icing wind tunnel engine intake simulation system,the air intake characteristics of typical low-flow engine intake components were analyzed,and a small-flow engine intake simulation method was developed.A water ring vacuum pump was proposed to solve the problem that the pressure of the suction pipe was greatly reduced due to the large flow resistance of the intake.On this basis,the engine intake simulation system was optimized,and the process of conducting the anti-icing test of the low-flow engine intake components in the icing wind tunnel was established,which was applied to the anti-icing test of a certain type of low-flow engine intake components.The results showed that the engine intake simulation system met the requirements of the anti-icing test of the low-flow engine intake components,and the control accuracy of the intake flow reached±0.05 kg/s(±0.33%FS).The flow change during the test can be used to identify the anti-icing effect.The relevant research can provide a reference for the design and optimization of the engine intake simulation system and the assessment of the anti-icing characteristics of the low-flow engine intake components.
