Unformatted text preview: (shown below) with a leading edge angle of 10o and a chord or 2 m. Due to the nature of the thin airfoil it is safe to assume all 4 sides of the diamond are 1 m long each. M∞ 10o a. b. c. d. e. Calculate the pressure on all four surfaces of the airfoil if it is flying at 4o angle of attack. Calculate the lift and drag of this airfoil flying at 4o angle of attack. Calculate the pressure on all four surfaces of the airfoil if it is flying at 5o angle of attack. Sketch the airfoil and all waves produced for both cases of (i) 4o and (ii) 5o angle of attack. At what angle of attack would the shock detach from the lower surface? 3. A diffuser has a constant area until the area shrinks by means of a sudden turn at an angle of 10o. The Mach number in the diffuser before the turn is M=5 and t...
