tunnel of plant 181
6.4 Introduction to Typical Low-Speed Wind
Tunnels
1. Aeroacoustic wind tunnel with low turbulence
Beihang University built a 1 m × 1 m low-speed loop wind tunnel (as
shown in Fig. 6.19) in Shahe, Beijing in 2013. It is a low-turbulence
aeroacoustic wind tunnel (referred to as “D5 aeroacoustic wind tunnel).
Not only aircraft aerodynamic layout pre-study, steady and unsteady
experiment, fluid mechanics and aerodynamics of fundamental research
but also aerodynamic noise mechanism and air dynamic noise reduction
