CFD方法在背负式进气道堵锥风洞试验模型设计中的应用

The CFD Methods Application During the Design of Back Mounted Air Intake Blocking Taper Wind Tunnel Test Model

在飞机的测力风洞试验中,为了模拟进气口附近流场,通常在进气道前设计堵锥,但对于背负式进气道飞机,常规的进气道堵锥设计可能不再适用。本文通过CFD方法进行了进气道堵锥类型的选择,使试验中风洞模型进气道附近流场的流态具有更高的相似性。

For the purpose of simulating the flow field around air intake, air intake blocking tapers are often designed in the wind tunnel test. But ordinary air intake blocking taper design may be not appropriate for some kinds of aircrafts which install air intakes above fuselage. By using CFD methods to select the forms of air intake blocking tapers, the flow field around air intake is more authentic in the wind tunnel test.
