摘　　要：为了确定布撒器的气动特性 ,在中国空气动力研究与发展中心高速所 0 .6m× 0 .6m风洞中进行了 1 :7缩比模型常规测力试验。实验结果表明 :在实验攻角下 ,布撒器横向稳定 ;在小攻角下布撒器呈方向静安定 ;如果俯仰舵偏为可用偏转角度的一半 ,布撒器纵向最大配平攻角约为 4°～ 6°之间 ;如果采用全部舵偏 ,布撒器在所有实验攻角下均可配平。A series of wind tunnel tests on a 1:7 scaled model was conducted in CARDC to determine the dispenser aerodynamic characteristics. Analysis of these test results revealed that:(1)The dispenser is stable in roll at all angles of attack in tests and is stable directionally at lower angles of attack.(2)Longitudinal trim could be achieved at all angles of attack if the maximum control surface deflection was available. (3)If only half of this deflection was available, the trimmed angles of attack were limited below 4°～6°.
