立式风洞设计关键技术探索与实验研究

The experimental research for the key technology of the vertical wind tunnel

试验段气流速度快速调节、试验段碟形流场分布、风洞振动与试验段气流脉动的抑制是立式风洞研制的关键技术。本文简介了对这些技术的探索与设计思路 ,并通过分析0 .33m立式风洞中进行的一系列性能研究试验结果 。

The key technologies for the vertical wind tunnel's design include adjusting of flow velocity rapidly, forming dish shape of the velocity in the test section and constraining the pulsation of the flow. This paper presents the researching on the aerodynamic design and the experimental results in a 0.33m vertical wind tunnel.
