Problem 6.040 As a means of preventing ice formation on the wings of a small, private aircraft, it is proposed that electric resistance heating elements be installed within the wings. To determine representative power requirements, consider nominal flight conditions for which the plane moves at 160 m/s in air that is at a temperature of -23°C. If the characteristic length of the airfoil is L = 2 m and wind tunnel measurements indicate an average friction coefficient of C =...
