    Abstract

    The wind tunnel is one of the oldest tools for research in !he field of aeronautical engineering. In order to study quantitatively the aerodynamic forces and the characteristics of air flow over bodies placed in an air stream the need was felt for a suitable device to create an artificialwind inside a tunnel shaped duct and hence13; shaped duct and hence, the name wind tunnel was given to this device. By means of a wind tunnel,. one can determine the air resistance acting on aero. planes, the forces that provide lift, the moments involved in pitching, yawing13; and rolling motions of the aeroplane, the forces necessary to deflect its control surfaces such as ailerons, rudder and elevators and also its flying qualities as regards stability, stalling, manoeuvrability and so forth.
