| 31. | Special bracing wires with flat or aerofoil sections were also developed in attempts to further reduce drag.
|
| 32. | There were two examples built of an aerofoil-fuselage design originally developed by Vincent J . Burnelli.
|
| 33. | This aerofoil lift produces helpful motion to windward & the corollary of the reason why lee helm is dangerous.
|
| 34. | All modern civil airliners use forms of supercritical aerofoil and have substantial supersonic flow over the wing upper surface.
|
| 35. | When the Darrieus rotor is spinning, the aerofoils are moving forward through the air in a circular path.
|
| 36. | The thickness distribution for a NACA 4-series aerofoil was used, with a 12 % thickness ratio.
|
| 37. | Accurately profiled root and tip aerofoil sections were made in thick metal and carefully secured to one half wing.
|
| 38. | Its surfaces therefore are symmetrical and not uneven like the aerofoils which give the returning boomerang its characteristic curved flight.
|
| 39. | The aerofoil section means that they can still provide significant lift when parked overhead, unlike leading edge inflatable kites.
|
| 40. | Hemp fibers are mainly used for ropes and aerofoils because of their high suppleness and resistance within an aggressive environment.
