You are analyzing an airplane with a weight of 11,000 lb, wing area of 280 ft, wing span of 46 ft, and a CD,o of 0.027. The airplane is cruising at an altitude of 20,000 ft a. Construct a graph of the parasite thrust required versus velocity. (velocity range of 100- 600 fps) (2 pt) b. Construct a graph of the induced thrust required versus velocity. Assume a reasonable Oswald's efficiency factor and report that value as well. (2 pt) c. Construct a total thrust required versus velocity graph. Include the previous two lines on the same graph. (3 pt) d. Construct a total thrust required graph for the same airplane at sea-level. Make sure the y-axis maximum is the same as the graph in c). (3 pt) e. Comment on the difference between the sea-level and 20k ft graphs. (1 pt)
