2. (8 points). Consider a thin airfoil (flat plate) pictured below. It is flying in air (y = 1.4) at an angle of attack

2. (8 points). Consider a thin airfoil (flat plate) pictured below. It is flying in air (y = 1.4) at an angle of attack a. Lift is provided by the high pressure on the lower side generated by an attached oblique shock and low-pressure attached flow on the upper side that turns through an isentropic expansion fan. M M2 P2 a M3 P P3 What is the largest angle of attack, for which this situation can be realized if: a. (4 points). M = 8.0? Explain the limitation. b. (4 points). M = 1.5? Explain the limitation.
