设计了侧压角为 6° ,后掠角 4 5° ,斜楔板压缩角分别为 4°和 8°的两套带隔离段的高超三维侧压式进气道 ,通过风洞实验研究了来流马赫数、出口反压、斜楔板压缩角以及隔离段等对进气道性能的影响。实验结果表明 ,在高来流马赫数及较小的斜楔板压缩角时 ,进气道的流量系数、总压恢复系数较高。总增压比在不同斜楔板压缩角时基本保持不变。 |

Abstract: |
Two types of three dimensional sidewall compression inlet models with 6° sidewall angle,45° swept angle and isolator were designed and experimentally investigated.The models were specially designed in 4° and 8° ramp angle.The Mach numbers of wind turnal were 5.3 and 3.85.The experimental results indicated that mass flow rate and total pressure recovery are higher in the condition of higher Mach number and lower ramp angle.Static pressure ratio in model remains constant in the condition of different ramp angles. |
