摘　　要：在高速风洞中对单喷模型喷流干扰和二次引射实现推力转向进行了试验研究,试验马赫数为0.6和0.8。结果表明:亚、跨声速喷流对气动特性起到积极作用;引入二次流可以实现喷流偏转,但是会带来一定的推力损失。The paper described the jet interaction to the aerodynamic characteristics of the model with single nozzle and the test of thrust vectoring using second-fluidic injector in FL-2 high speed wind tunnel,while the test mach-numbers are 0.6 and 0.8.The results indicated that the exhaust was of advantage to aerodynamic characteristics at subsonic and transonic speed.And the thrust vector can be achieved by using second-fluidic injector,but some thrust loss as a result of second-fluidic.

关 键 词：二次引射 喷流干扰 推力矢量
