| 11. | Wind tunnel tests showed the tunneled rear window caused lift and the gaping mouth induced drag.
|
| 12. | The trailing wingtip vortices are responsible for the component of the downwash which creates induced drag.
|
| 13. | This formula demonstrates that a sail's induced drag coefficient decreases with increased aspect ratio.
|
| 14. | Overall fuel efficiency improvement is up to five percent through the reduction of lift-induced drag.
|
| 15. | Wingtip vortices are associated with induced drag, an unavoidable consequence of three-dimensional lift generation.
|
| 16. | For a given wing span and surface, minimal induced drag is obtained with an aspect ratio.
|
| 17. | The vortices trailing a bird create an underwash, which creates an induced drag for the bird.
|
| 18. | Studies had long shown that the ideal wing for minimizing induced drag should be an elliptic planform.
|
| 19. | In gravitational deposition, this velocity is the settling velocity due to the gravity-induced drag.
|
| 20. | In theory, induced drag is at its minimum when the spanwise distribution of lift is elliptical.
