尾支杆干扰非线性修正方法的初步研究

Preliminary research on non-linear correction method of sting interference

摘要: 利用CFD方法,采用两套网格重叠的形式,研究了一种对尾支杆干扰进行修正的非线性方法。运用本方法,研究了尾支杆等直段长度、直径和锥角对模型气动特性的影响,研究了四个模型有攻角时的尾支杆干扰,并对GBM-04A模型的零阻进行了尾支杆干扰的修正。

Abstract: A non-linear correction method of sting interference is presented by using CFD and overlap grid.Using this method,the sting effects such as sting length,diameter,conical degree,or model with angle of attack,on aerodynamic characteristics of model are investigated,and corrections of sting interference to drag of GBM-04A are applied.
