| 1. | Modern jet aircraft use supercritical airfoils which decrease wave drag significantly.
|
| 2. | There are two effects in particular, wave drag and critical mach.
|
| 3. | Wave drag presents itself as part of pressure drag due to compressibility effects.
|
| 4. | At even higher speeds in the transonic, wave drag enters the picture.
|
| 5. | Wave drag is created by every movement a swimmer makes in the water.
|
| 6. | This creates a force known as wave drag.
|
| 7. | This wave drag increases steeply until the whole aircraft is supersonic and then reduces.
|
| 8. | The formation of these shockwaves causes wave drag.
|
| 9. | These changes delay the onset of wave drag.
|
| 10. | Aircraft flying at transonic speed often incur wave drag through the normal course of operation.
