The wing of the glider shown above has an aspect ratio of 14, and its airfoil is an NACA 4415. The span efficiency factor is 85%, and the wing area is 230 f2. The wing is flying at 4 degrees angle of attack. The glider is cruising at 75 knots at 6,000 feet. Assume the Reynolds number is 9(10). Determine the three-dimensional lift and drag coefficients, and the lift and drag for the wing. Solve the problem in the English system of units.
