They have a wing span of around 2.75 meters (9 feet).
它们翅翼展开可达二点七五米(9英尺)。
However, by combining the use of trailing-edge flaps with leading-edge slats, the wing's lift coefficient can be effectively doubled if used on the full span of the wing.
然而板条，结合边缘皮瓣与领先使用的后缘，机翼的升力系数，可有效地增加一倍，如果用在机翼完整的跨度。
Some eagles have a wing span of one and a half meters.
有些鹰的翅膀展开长达一米半。
Built from carbon fibres and balsa wood, Snowbird has a wing span of 32m (105 feet) - comparable to a Boeing 737.
雪鸟是由碳纤维和轻质木制成的，机翼长总32米(105英尺)，堪比波音737。
The lift coefficient can thus be effectively doubled with relatively simple devices (flaps and slats) if used on the full span of the wing.
该升力系数因此，可以有效地增加一倍，相对简单的装置(襟翼和缝翼)，如果使用对充分跨度机翼。
Tip vortex goes downstream outward along the span direction, and the induced drag of the wing decreases.
翼尖涡沿着展向方向向外移动，机翼诱导阻力减小。
