PART 1: Solve these problems: 1. A 10858-lb aircraft has an (L/D)MAX value of 9.8; find its minimum drag. To find minimum drag, use this equation: Dmin W (+) max 2. If the aircraft in Problem 11 has a wing area S=224 ft2 and the value of CL=0.5 at L/DMAX, find the sea level airspeed where DMIN occurs. 3. For problem 1, find Di and D at (L/D) MAX. 4. For problem 1, complete the following table and plot Di. Dp, and Dt 125 150 172 200 300 400 (V+ V) D = Dmin (V+V) (V V) |Di = } Dmin(Vi = Vy) Dr = D +D. PART 2: Once created, utilize your derived table and diagram data to answer the following associated questions: A. What are the minimum drag parameters of a Boeing 747? Minimum drag value D(min) Speed VD (min) at which minimum drag occurs Relationship between Dp and Di at D (min) B. What are the maximum lift to drag ratio CL/CD parameters of a Boeing 747? (CL/CD)max value Speed at which (CL/CD)max occurs C. Compare answers in A and B and comment on the findings. D. Explain which of your derived values will allow glide performance predictions for a Boeing 747 and quantify best glide conditions with specific values. E. Explain the origin and effects of aircraft design and operating influences on induced drag. F. Explain sources of parasite drag and methods to reduce it.
