摘要: 给出了一套参数化研究短舱气动性能的方法,主要包括总压恢复系数、静态畸变指数、阻力系数、压力系数、流量系数等5个参数。重点研究了影响短舱气动性能的进口形状、唇口前缘半径2个要素。比较3种考虑层流原理设计的短舱发现,无攻角状态不同进口形状的短舱气动性能相差很小,椭圆形进口短舱的综合气动性能略好于其他2种进口形状短舱的。不同唇口前缘半径的短舱在高速攻角侧滑角状态下气动性能差别较大,大唇口前缘半径的短舱综合气动性能明显偏低,低速状态则综合气动性能差别较小。

Abstract: A parameterization investigation method for nacelle aerodynamic performance is presented, mainly including five parameters:total pressure recovery coefficient,static distortion index, drag coefficient, pressure coefficient, and flow coefficient. Two elements influencing the nacelle aerodynamic performance are dominantly investigated. Comparison of three types of nacelles considering the laminar flow principle reveals that the aerodynamic performance of nacelles with different inlet shapes is nearly the same with no angle of attack, while the comprehensive aerodynamic performance of the nacelle with the ellipse shaped inlet is slightly better than that of the other two with different inlet shapes. The aerodynamic performance of nacelles with different inlet lip leading radii exhibits considerable differences at a high speed with a high angle of attack and sideslip. The comprehensive aerodynamic performance of the nacelles with a large inlet lip leading radius is clearly low, while that of the nacelles at a low speed shows almost no difference.

Key words: parameterization, nacelle, inlet shape, inlet lip leading radius, comprehensive aerodynamic performance
