The Mk I variant of the Supermarine Spitfire (shown below) first flew in 1936. Its maximum speed at 18,500 ft altitude was 165m/s. It's loaded weight was 2639kg, wing area 22.5m2, wingspan 11.23m and its supercharged Merlin powerplant produced 1050 horsepower at this altitude. (At this altitude, density p= 0.7 kg/m3; also assume e = 1). а) %3D i) Calculate the coefficient of lift (CL) and the induced drag (CDi). ii) What percentage of the total drag coefficient is due to induced drag? (Assume steady, level flight, and assume that 90% of the engine power is converted to thrust by the propeller). iii) Find the induced drag coefficient for the Spitfire on landing approach at sea level (density p= 0.7 kg/m3) at a speed of 30m/s. Compare this result to your answer for part (ai), and comment on the importance of the induced drag coefficient at low speeds compared to that at high speeds.
