| Abstract: | In this paper a complete design and construction of the straight flow low speed wind tunnel test platform is intro-duced, and the speed of the air flow, pressure, and temperature test with pitot tube in different locations and depth in the ex-perimental section are performed.The quality of the flow field with honeycomb device and rectified net is improved.Tested and compared on the uniformity and stability of the air field, the results show that the improved straight flow low speed wind tunnel test platform has good airflow flow field, which meets the basic requirement and can be carried out the simple experi-mental model test. |
