blended wing-body

...In addition, a curved double delta wing planform is sometimes called an ogee wing, and there is also a planform that combines a delta wing with a wing of a slightly larger aspect ratio, taking advantage of the property that the vortex generated by a sharp delta wing prevents stall and increases lift up to a large angle of attack, in which case the forward delta wing part is called a strake. In addition, when these wings are integrated with the fuselage and aerodynamically designed as one unit, they are called a blended wing-body, and generally the boundary between the wing and the fuselage is smooth. [Kuse Shinji]
[Names of each wing part]

…なお，二重三角翼の平面形を曲線的にしたものをオージー翼ogee wingと呼ぶこともあり，また鋭い三角翼で発生する渦が大迎え角まで失速を防ぎ揚力を増す性質を利用して，三角翼を一般のアスペクト比のやや大きい翼と組み合わせた平面形もあり，この場合，前方の三角翼部分をストレーキstrakeと呼ぶ。なお，これらの翼を胴体とまとめて一体として空力設計したものは翼胴一体化blended wing‐bodyと呼ばれ，一般に翼と胴体との境目がなだらかになる。【久世 紳二】
