Interestingly enough, several of these hydrodynamic adaptations resemble features designed to improve the aerodynamics of high-speedaircraft.
有趣的是，这些流体动力学的适应性变化和人类为了改进高速飞机在空气动力学方面的设计特点十分相似。

High-speedaircraft usually employ thin, low-drag, low-lift airfoils; slow aircraft that carry heavy loads use thicker airfoils with high drag and high lift.
高速飞机通常采用低阻力、低升力的流线型薄翼型，载重量大的低速飞机使用高阻力、高升力的厚翼型。

It is designed to perform conventional helicopter missions but with the long-range, high-speed cruise performance of a turboprop aircraft.
