Use the vortex lattice program AVL to estimate the lift and drag characteristics of the Boeing 737-800. You can obtain the program and a geometry file for the aircraft at: http://web.mit.edu/drela/Public/web/avl/ Assume the aircraft is flying in SLUF conditions with W= 174,200 lbs flying at M = 0.7 at 30,000 ft. 1. Use AVL to find the following information for the aircraft: a. Angle of attack of the aircraft b. Lift distribution c. Induced drag coefficient d. Induced drag in pounds 2. Use the results of lifting-line theory (Eqns. 7.29, 7.30, and Fig. 7.14) to find: a. Angle of attack of the aircraft b. Induced drag coefficient c. Induced drag in pounds Compare your results and comment on the accuracy of AVL and the ease of obtaining your results with both methods.
