A kite flying in air may be considered equivalent to a rectangular aerofoil with a 950 mm chord and2.1 m span. During stable flight, it faces a horizontal wind of 12 m s at 12° to the horizontal,resulting in a tension in the guide rope of 101 N. The rope is at 7° to the vertical and the airtemperature and pressure are 15 °C and 1 bar, respectively. The universal gas constant is R = 8314 Jkmol1 K1 and molar mass of air is M = 29 kg kmol.%3D (i) Calculate the lift and drag coefficients. [7 marks] (ii) Estimate the contribution of induced drag. [1.5 marks] (iii) Calculate the minimum wind speed that would be required to lift a 70 kg body upwards. You can assume that a change in Reynolds number does not vary the lift coefficient. [4 marks]
