| 21. | A symmetrical airfoil will generate zero lift at zero angle of attack.
|
| 22. | Cambered airfoils will generate lift at zero angle of attack.
|
| 23. | The pressure difference that exerts lift acts directly on the airfoil surfaces.
|
| 24. | Others use an airfoil on a pivoting spar, as with windsurfers.
|
| 25. | The terminal's roof is shaped like an airfoil.
|
| 26. | A deep airfoil section centerboard and rudder make the Albacore highly manoeuvrable.
|
| 27. | Other software by Rogue Amoeba includes Nicecast, Airfoil, and Fission.
|
| 28. | Kawalki's airfoil shapes were identical to Richard Whitcomb's.
|
| 29. | The wing airfoil was too thin to house conventional landing gear mechanisms.
|
| 30. | The airfoil selected for the design was the NACA 64A215.
