| 21. | For low Mach number \ scriptstyle Ma, the drag coefficient is independent of Mach number.
|
| 22. | Also, compression of the fluid is not applicable, so the Mach number can be disregarded.
|
| 23. | Conversely, the Mach number of a supersonic flow will decrease until the flow is choked.
|
| 24. | The Me 262 appeared to have a higher critical Mach number than any American fighter.
|
| 25. | As a rough guide, compressible effects can be ignored at Mach numbers below approximately 0.3.
|
| 26. | These problematic phenomena appearing at or above the critical Mach number became known as compressibility.
|
| 27. | A swept wing delays the onset of this problem by increasing the critical Mach number.
|
| 28. | The Mach number range can also be extended beyond M 1cr by carefully designing blade shapes.
|
| 29. | This is also a function of Mach number:
|
| 30. | Interestingly, the intersection points occur at the given initial Mach number and its post-normal shock value.
