3. You are assigned the task of designing the inlet of a ramjet, consisting of a Prandtl-Meyer compression fan followed by an oblique shock, as follows: Mos P Too B The inlet is to be designed such that the air has a Mach number of 2 at the inlet exit (after the oblique shock), and such that the temperature ratio across the oblique shock is equal to the temperature ratio across the compression fan. For Moo-5, Poo-0.2 atm, Too-250 K, and H=1 m, perform the following: (a) Find the Mach number, pressure, and temperature after the compression fan ahead of the oblique shock ANS 3.37, 1.65 atm, 457 K (b) Find the pressure and temperature after the oblique shock ANS 8.71 atm, 834 K (e) Find the angle 0 (the angle between the cowl and the X axis) ANS-3.5⁰ (d) Find the angle 81 (the angle between the ramp and the X axis) ANS 20.5⁰ (e) Find the X-y coordinates of point C ANS 4.9 m, 1.0 m.
