Annotation: The paper represents a new method of modeling overground athmospheric boundary layer for air dynamic tubes with the short working part to adapt laboratory installations for constructions tests. Classic air dynamic tubes have short working sections (not less than the section height) with the low turbulence. From the wind engineering modeling requirements it is clear that to obtain exat results it is necessary to model the atmospheric boundary layer. When designing, the strong wind is subjected to tire insignificant influence of thermal stratification is the most important factor. That is why the running is flow is usually isothermal, which models thermally neutral atmospheric boundary layer. Aerodynamic tubes, elaborated for sush a flow type are classified as the aerodynamic pipes with boundary layer. The new generator vortex gives the opportunity to provide the steeples regulation of boundary-layer thickness, the same vortex-generators using and at the expense of this experimental possibilities of the numerous existing aviation aerodynamic tubes with short operating section, enables to carry out the meteorological investigations in them.
