Consider the Supermarine Spitfire.Its maximum velocity is 362 mi/h at an altitude of 20.500 ft.Its weight is 5820 Ib,wing area is 242ftand wing span is 36.1 ft.It is powered by a supercharged Merlin engine,which produced 1050 horsepower at 20.500 ft.The induced drag coefficient of the Spitfire is 0.001109.If the elliptical wing of the Spitfire were replaced by a tapered wing with a taper ratio of 0.4.calculate the induced drag coefficient and the percentage increase with the given value.Round the induced drag coefficient to five decimal places and percentage increase to one decimal place.) The following graph is a plot of induced drag.factor as a function of taper ratio. 0.16 0.12 0.08 AR 0.04 0 0.2 0.4 0.6 0.8 1.0 Taper ratio,c./c The induced drag coefficient is The percentage increase is %
