Document Summary
Mechanical & aerospace engineering aero 4306: l yaras open books and notes, calculator. Students must count the number of pages in this examination question paper before beginning to pages. write, and report any discrepancy immediately to a proctor. This examination question may be taken from the examination room. They are of equal value: a rectangular wing (. aspect ratio : i l) is being designed to give an elliptic lift distribution at cruise: : , 2 r - l - l - l. The airfoil section is a naca 631412, and the angle of attack at the root (50) is 5. 5 degrees lor cruise conditions. Determine the cruise lift and drag coefficients: a communications satellite was carried by the space shuttle into a leo (low earth. Orbit) at an altitude of 322 km and is to be transferred to a geo (geosynchronous earth. Orbit) at 35,890 km using a hohmann transfer.
