摘    要:在模拟实际发动机喷管落压比的情况下,利用轴对称矢量喷管的缩比模型,对其壁面静压分布进行了试验研究.研究结果表明,当矢量偏转后,轴对称矢量喷管的收敛段与扩张段内流场均呈现出复杂的三维流动的特征;当喷管落压比小于完全膨胀落压比时,喷管内部存在周向不对称的斜激波和分离区,且激波位置随几何矢量角的增大而前移.本文的研究结果可用于检验喷管三维流场的计算精度.

关 键 词:矢量控制  喷管  静压测量  试验研究

Abstract:An experimental investigation has been conducted with a scale model to determine the wall static pressure distributions of an axisymmetric vectoring thrust nozzle (AVEN) with different nozzle pressure ratios (NPR).The results indicate that the internal flow characteristics is complex 3 Dimensional in convergent and divergent sections at flow vectoring,and the shock waves as well as flow separations appear non symmetrical and vary with the geometric vector angle while the NPR was less than design pressure ratio.
Keywords:nozzles vector control  static pressure distributions  experimental investigation
