Abstract
Currently in aeronautics the aims and objectives of wind tunnels experiment are diverse. It could be purely for optimising the aerodynamic design at the high speeds (transonic for the transport aircraft) by conceiving efficient wing sections, coupling the structure and aerodynamics (optimised volume, lighter structure, aeroelastic behaviour), developing innovative deployable surfaces to achieve high lift at low speed, controlling the plane’s behaviour (performance, manoeuvrability and flight envelope) up to maximum lift coefficient and beyond stall. In the field of terrestrial vehicles, the objectives are to decrease the drag in order to reduce the fuel consumption, to guarantee the stability of the vehicle (response to cross wind) and to increase interior comfort by reducing aerodynamic noise.
