摘　　要：为了对旋转冲压压缩转子试验系统中排气支板进行研究,采用Fluent流体计算软件对不同支板转角以及在支板段加装分流叶片时旋转冲压压缩转子试验系统通流部分进行数值模拟。结果表明:支板转角为30°时,在效率保持不变的情况下,旋转冲压压缩转子压比相比原型提高了1.23%,支板段总压恢复系数提高了5.56%。支板在转角为20°时其进出口的密流最大,流通能力最强。当支板加装1片分流叶片时,旋转冲压压缩转子的压比及效率分别比原型提高了0.18%和2.6%,此时支板段的总压恢复系数比原型提高了5.54%,支板进出口的密流最大,流通能力最强。In order to figure out the support segment of the ram-rotor test system, the Fluent software was adopted to simulate the flow passage of the ram-rotor test system at different support segment rotation angles and mounting splitter blades numerically. Results show that when the support segment rotation angle is 30,°with the efficiency of the ram-rotor remaining constant, the pressure ratio of the ram-rotor is increased by 1. 23% compared with the prototype case, and the total pressure recovery coeffi-cient is increased by 5. When the support segment rotation angle is 20°, the inlet and outlet density flow of the support seg-ment remains maximum and it has the best flow capacity. If mounts 1 splitter blade on the support segment, the pressure ratio and efficiency of the ram-rotor are increased by 0. 18% and 2. 6%,respectively,compared with the prototype case, the total pressure recovery coefficient is increased by 5. 54%. The inlet and outlet density flow of the support segment are also maximum, and the flow capacity of the support segment is the best
