SYSTÉM MERANIA AERODYNAMICKÝCH SÍL V DEMONŠTRAČNOM VETERNOM TUNELI

Abstract

The purpose of the article was to solve a part of the wind tunnel, specifically part of the measurement of wind forces. The work deals with the mechanism by which it is possible to determinate the values of bouyancy, downforce and drag of the object, which is attached to the system. The work takes into account the conditions under which the mechanism had to be constructed. Selection of suitable material due to price and quality, dimensional conditions, method of measuremnt system itslef and output from the mechanism. In addition to the design itself, the scope of work also included a summary of the current state in the field of aerodynamics and wind tunnels, an analysis of current requirements for the operation of wind tunnels and a final summary from a technical and economic point of view. At the beginning of the work are summarized the basics of general aviation and the importance of aerodynamics associated with it. The second part of the work is a wind tunnel, its importance for aviation and then its design and construction of a functional mechanism for measuring the required parameters. Due to the fact that the wind tunnel was built by students and employees of the University, the work includes its own practical experience.
