摘要
采用有限基本解方法对机载布撒器翼身组合体亚音速气动特性进行了数值计算.利用回转体对称特性,在体轴上布置线源和基元旋涡,模拟布撒器弹身的纵横向气动力.弹翼的升力问题采用涡格法,布置马蹄涡予以解决,厚度问题用简化的线源模拟.此法简单,具有一定精度.文中计算了一些实例,并与其它方法进行了对比.
In this paper the aerodynamic characteristics of airborne dispenser wing body combinations are caculated by use of finite elementary solution method. Linear source and elementary vortex are located at the body axis of airborne dispenser in order to simulate the lateral aerodynamic force because of the axis symmetric character of the body. The problem of wing lift is solved by use of vortex lattice method in which the horse shoe vortexes are located. The problem of wing thick is solved by use of linear source. The method is simple and accurate. Several examples are calculated by this method and compared with other methods.
