Problem 1 (30 points): A two-dimensional flat plate is held at a negative Angle-of-Attack (ADA) in a Mach-3 supersonic stream. An oblique shock wave making an angle of 35 with the incoming flow direction is present at the leading edge. Expansion waves emanate from leading edge extending over the lower surface. Approach flow static pressure is, PI-1 atm,. For these conditions, A-5 pts) Determine the AOA of the plate. B-15 pts) Calculate the pressure on the top surface of the plate. C-10 pts) Calculate the static pressure at the bottom of the plate. M=3 P=1 atm AoA 35"
