1. Introduction

UTAD-2 is an atmospheric low speed wind tunnel of closed-return type with open elliptical test section. It is used for educational purposes in aerodynamics and flight dynamics as well as for scientific investigations, and commercial purposes such as certification of wind velocity and wind direction meters. Methodological works like working through of new types of experimental rigs, data acquisition and processing approaches, etc. are performed, which are then implemented in large TAD-2 wind tunnel.
