摘要:

在双三角翼、椭圆机身的先进战斗机气动布局中配置舵面矢量推力装置,系统研究了该舵面矢量推力装置引起的纵向矢量喷流和横向矢量喷流对机翼绕流及其气动特性的影响,同时还研究了舵面矢量喷流的落压比NPR、舵面的纵向和横向偏角Dp、Dy以及纵向舵面的宽度W和舵面的配置等因素对喷流干扰效应的影响。

Abstract:

An experimental investigation was carried out in the BUAA D 1 low speed wind tunnel to determine the vane thrust vectoring jet effects on aerodynamic characteristics of the modern fighter model.Based on the advanced fighter configuration with double delta wing and elliptic body,the three vane thrust vectoring system is installed in it.The effects of longitudinal and lateral vectoring jet on the flow patterns around the fighter model and its aerodynamic behavior are studied in detail.The vectoring jet interactive effects from parameters including vectoring jet pressure ratio p0j /p, longitudinal and lateral deflection angles of vanes Dp  and Dy, the width Wp of longitudinal vane are also studied.

Key words: jet, t hr ust vector, aerodynamic cha racter istics
