The proposed drag reduction mechanism and drag reduction method are valuable both theoretically and in engineering to realize the low drag pipeline transport of highly viscous fluid.
所提出的减阻机理及工程减阻方法对实现高粘度流体的低阻力管道输送具有重要的理论指导意义和工程应用价值。
A next-generation combat drone, for example, might loiter for hours above a potential target on elongated, low-drag wings.
举例来说，新一代无人战斗机就可运用外张的低阻力机翼，在预定目标上空盘旋数小时。
High-speed aircraft 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。
This efficiency is due largely to the innovative design of the low-drag wing. This design includes leading-edge slats, double-slotted Fowler flaps, and high-Mach blended winglets.
如此卓著的效率应当归功于低阻机翼、前缘缝翼和双开缝襟翼，以及高马赫混合式翼梢小翼。
