Question 18 A thin cambered aerofoil has a parabolic camber line defined by z = ex(1 – x/c) where the chord c-20m, and the parameter e=003 and as shown in the figure below Z (Not to scale) Assuming that density is 1 225kgm and that the free stream velocity is 20m's answer the following questions using thin aerofoil theory What is the maximum value of on the aerofoil camberline? kW) What is the zero lift maidence of the aerofoil in degrees correct to 3dp? wcy What is the lift coefficient for the aerofoil at an angle of incidence of 4 degrees correct to 3dp? (iv) What is the corresponding value of lift in N for the incidence in (in) correct to 1dp?
