摘要
介绍了进气道隐身装置与某涡扇型发动机地面联合试验的设备组成与试验方法,分析了风扇形吸波导流体的隐身原理。通过实验,确定了吸波导流体对进气道气动性能的影响,考验了由复合材料构成的隐身装置的结构强度。
The paper introduces the experimental facilities for combining stealth device in air duct with turbofan engine.How the flow deflector affects the flow field of air duct was ascertained.The fan-shaped flow deflector was made of wave absorption material,its stealth principle is analyzed.The distributing of complicated inlet flow field and the analyses of distortion index are investigated.
