在双三角翼、椭圆机身的冀身融合体气动布局中配置二元矢量喷管,本文对该布局形式的矢量喷流和主流绕流之间的干扰流场及其对机翼气动特性的影响进行了系统的实验研究。结果表明,矢量喷流对主流及其气动特性的干扰效应可以分为三类:矢量喷流对附流的干扰效应仅限于喷口附近,主要表现为引射或阻塞作用;矢量喷流对前缘涡的干扰效应起稳定旋涡的作用,这样对稳定涡系的干扰影响很弱,但对破裂涡绕流的干扰效应较强,且随喷流矢量角的增大而增强。
The binary vector nozzle is arranged in the aerodynamic layout of the double delta wing and the elliptical fuselage. The disturbed flow field between the vector jet and the main flow and its influence on the aerodynamic characteristics of the wing The impact of a systematic experimental study. The results show that the interference effect of vector jet on the mainstream and its aerodynamic characteristics can be divided into three categories: the interference effect of vector jet on the advection is confined to the vicinity of the jet, which is mainly caused by catching or blocking; The interference effect of vortex plays the role of stable vortex, which has a weak influence on the stability of the vortex. However, the disturbance effect on the flow around the ruptured vortex is stronger and increases with the increase of the vector angle of the jet.
