. A light, low - wing aircraft employs an elliptically loaded wing in straight and level flight. A pitot - pressure probe is placed on the top of the tail fin ( on the aircraft centreline ) a distance 3 m behind and 1.2 m above the plane of the main wing. Calculate the flow velocity and direction (angle) at the point in question. Approximate the aerodynamics influence of the wing by a single bound vortex and two trailing vortices; ignore the effects of all other parts of the aircraft. Aircraft and flight data are: weight: 800 kg| wingspan: 9m cruise speed: 50 m/s ambient density: 1.23 Kg/m3
