Consider a 2-D airfoil with the diamond profile as shown below. (a) (5 points) On the upper surface, supersonic flow is first expanded through a Prandtl-Meyer fan, where the flow is deflected by d = 5 deg. Then, the flow is expanded again through the second Prandtl-Meyer fan, where the flow is deflected by d = 10 deg. Determine the P-M angles and Mach numbers along the upper surface, no, nu1, nu2, Mu1, and Mu2
