Its low sweep wing reduces drag and weight; the embedded engines sit aft of the wings.
它低水平的扫翼能够减少阻力和重量；嵌入式引擎安置在在扫翼的尾部。

Vibrating in the wind, the bristles create some drag. But they also reduce the wing's slipstream, an area of low-pressure turbulence that pulls back on the wing, and hence reduce drag.
The flaperons have their own airfoil, and are hung below the wing trailing edge to supply them with fresh undisturbed air for maximum control effectiveness even at low speeds.
