| 摘 要： | 本文介绍了北京航空航天大学IDT-1甲型引射式前导性跨音速风洞的研究工作,包括风洞实验段动态气流品质及引射效率（GT/Gj）等方面。在采取了多种技术措施后,表征实验段脉动压力的参数值达到或接近Lowson公式和Mabey准则所给出的值,使风洞这类性能进入世界同类研究的先进行列。引射效率和气流的湍流度也达到相当好的水平。实验研究还表明引射驱动方式应用于跨音速风洞具有光明的前景。

| Abstract: | The development of an injector driven transonic pilot wind tunnel (0.1 XXX 0.1m2 in size, type IDT-lA)in BUAA. is presented in this paper. The efforts consist of the improvements in dynamic flow quality and mass ef f iciency(GT/GJ) .Through various technical treatments, the pressure fluctuation level in the test section of IDT-1A, having contented or approached Lowson's Formula and Mabey's Criterion, has met the advanced world standard. The mass ratio and free stream turbulence have attained to considerably good level.Experimental results show a promising prospect for utilizing the injector driven technique in advanced transonic wind tunnels. |
