%X Statement of the problem. In order to study building aerodynamics, a scientific and industrial la-boratory was created at the Moscow State University of Civil Engineering for aerodynamic and aeroacoustic tests of building structures. The main research station in the laboratory was a wind tunnel. This paper describes a design of a wind tunnel to study the aerodynamic and acoustic ef-fects on buildings, structures and their elements.Results and conclusions. Different variants of principal schemes of wind tunnels were examined and developed. Preliminary calculating characteristics of the setup were obtained. The internation-al experienced of aero setup design was used in elaborating the structure. It was developed using numerical modelling and the method of a series of calculation of gas dynamics of an closed sub-sonic wind tunnel being designed. It was found that a modified structure with a 7-degree turn of a nozzle and operating area significantly improves gas dynamics in the operating area.
