High-lift device : ウィキペディア英語版 | High-lift device
In aircraft design, a high-lift device is a component or mechanism which increases lift beyond that obtainable from the main aircraft components. The device may be a fixed component or a movable mechanism which is deployed when required. Common high-lift devices include wing flaps and slats. Leading edge root extensions and boundary layer control systems are less commonly used. ==Purpose== The size and lifting capacity of a fixed wing is chosen as a compromise between differing requirements. For example a larger wing will provide more lift and reduce takeoff and landing distance, but will increase drag during cruising flight and thereby reduce performance when in flight. High-lift devices are used to compensate for some of these differences, allowing the use of a more efficient wing in flight, while adding lift for takeoff and landing.
