| 21. | The planform and aerofoil sections were computer designed for optimal glide over the speed range.
|
| 22. | The cross section of the cowling has the same shape as an aerofoil, says Frankovick.
|
| 23. | When inflated, the wing's cross-section has the typical teardrop aerofoil shape.
|
| 24. | The car could change its aerodynamic profile using an adjustable aerofoil located in the nose section.
|
| 25. | Phillips conducted extensive wind tunnel research on aerofoil sections, using steam as the working fluid.
|
| 26. | The engines would be on the ends of an aerofoil section to reduce the rotor loading.
|
| 27. | Also, early aerofoil sections were very thin, and could not have strong frame installed within.
|
| 28. | This mechanism is enhanced by making the leading edge of the aerofoil in this region relatively sharp.
|
| 29. | BERP IV uses : a new aerofoil, revised blade tip shape, and increased blade twist.
|
| 30. | The aerofoil was Joukowsky StAe-27A, a heavily cambered wingshape with a thick leading edge.
