1. No variation of density, speed of sound and Mach number is allowed. 2. It was repowered to to give Mach number 1 capability in 1945. 3. The wing-and tail-thickness ratio was also reduced to increase the critical Mach number . 4. The true airspeed corresponding to the critical Mach number generally decreases with altitude. 5. This graph shows relationship between shock loss coefficient and Rotor inlet Mach number 6. Mach number , Reynolds number ) are already linked in the text.7. The optimum flight Mach number for transition on the J58 was about Mach 2. 8. This is a reasonable assumption when the Mach Number is less than about 0.3. 9. For a supersonic flight Mach number , acceleration is typically achieved via a convergent-divergent nozzle. 10. The second difficulty occurs when the aircraft Mach number changes.
