Unformatted text preview: M&AE 3050 Practice Exam 2 Fa 2009 This is for practice only. You do NOT need to submit. 1. We wish to consider the effect of altitude on the difference between true airspeed and calibrated airspeed, making the following comparisons. (a) Determine the i. true airspeed; the ii. equivalent airspeed; and the iii. calibrated airspeed for flight at an altitude of h = 12 , 000 m in the standard atmosphere when the flight Mach number is M = 0 . 80. (b) Repeat the calculation of true, equivalent, and calibrated airspeed for flight at the same Mach number, but at standard sea level conditions. 2. The North American Mustang P-51 was one of the first aircraft designed to incorporate a laminar flow wing. For the purpose of estimating skin-friction drag on this aircraft, we will approximate the wing as a flat plate having a rectangular planform of span b = 37 ft and mean chord c = 6 . 3 ft. We wish to estimate the skin friction drag on the wing at a speed of V = 440 mph at h = 25 , 000 ft in the standard atmosphere for several different scenarios, as described below....
