Question details

Consider an airplane with a weight of 2000 lbs and a trapezoidal wing that is unswept about the quarter chord reference line. The wing has a span of 36 ft, a root chord of 6 ft, and a tip chord of 3 ft. The airplane is operating at 5000 altiude at a speed of 100 KTAS, and the wing is elliptically loaded at this flight condition 1. a. b. c. d. What is the wing area, S, in square feet? What is the wing lift coefficient, CL? What is the airfoil section lift coefficient at the wing root (y - 0)? What is the airfoil section lift coefficient at the midpoint of the wing semispan (y- 9 ft)? What is the airfoil section lift coefficient at the wing tip (y Ξ--18 ft)? e. f. Plot the ratios (cy)())/(c(0)cI(0)), c(y)/c(0), and c(y)/c(0) on a single plot axis vs. the x-axis variable 0 y/(b/2)S1. Make this plot using a dense sampling of y values along the span, not just the three values from parts (a) - (c) above. Use a legend and different line types or colors to denote each curve. Discuss the reasons for the shape of ci(y)/ciC0).
