舵面矢量喷流对现代战斗机气动特性的影响

Abstract

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 p_0j /p_∞, longitudinal and lateral deflection angles of vanes D_p  and D_y, the width W_p of longitudinal vane are also studied.

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