3. [12 points] A diamond-wedge supersonic airfoil with a half-angle -10° is in a freestream of Mach number M₁-3 and static pressure corresponding to sea level of pi-101375 Pa. If the airfoil is at an angle of attack of a=10°: a) sketch (in your exam booklet) the major features of the flow around the airfoil, b) Find M and Po/P ratios for each region (1, 2, 3, 4, and 5), c) calculate the c/ and ca of the airfoil if the length of each face is / and the chord c. 2 3 M₁ = 3 с 1
