Designed as a closed circuit with controlled wind velocity and temperature conditions. It consists of climatic and aerodynamic parts. While the aerodynamic part provides well-fitted conditions to study wind effects on scaled model of prototypes, an equipment of the climatic part is suited for investigation of influences of weather including the wind, temperature, rain and heat radiation. Using the cooling/heating exchanger, cycle temperature changing of the airflow is available in the whole tunnel within the range of -10 to 30 C in relatively short time period. Integral part of the tunnel equipment consists of instruments for airflow diagnostic, data acquisition system, direct pressure surface measurement, precise thermometry and of many other types of handy accessories for instant use. Workshops for manufacturing of testing models are available in the same building.
