摘要
本文通过对某型直升机机身/进气道内外流场耦合的数值模拟,介绍了CFD技术在直升机内?外流场的计算能力。分析了进气道形状对进气道出口压力畸变的影响。最后通过改进进气道的外形,气动性能指标有一定的改善。
the paper introduce a CFD calculation for inside and outside coupled flow field of helicopter fuselage/intake,And analyse the pressure aberration from effect of intake shape.At the end,through change the intake shape,the aerodynamic performance target receive some improve.
