Question
A supersonic aircraft flies with a speed of 2750 km/h at 27 °C and 100 kPa weather conditions. Two oblique shock waves are generated at leading nose and front window edges as shown in Figure (1). The deflection angles of nose and window edges are 15° and 9° respectively. Determine: 1. Mach number upstream the first shock wave (M1) 2. Normal Mach number upstream the first shock wave (Ma1) 3. Normal Mach number downstream the first shock wave (Myı) 4. Mach number upstream the second shock wave (M) 5. Normal Mach number upstream the second shock wave (M2) 6. Normal Mach number downstream the second shock wave (My2) 7. Mach number downstream the second shock wave (M3) 8. The pressure downstream the second shock wave. Take (y=1.4 and R = 287 J/kg.K) for air. Oblique shock waves M3 ? T1=27°C 9° M2 P3 ? P1 =100 kPa HHAUR HANCE 15° 1.22 1.62 0.72 1.45 2.2
