In addition, due to the streamline surface, the shaperesistance is reduced, thus lowering the flowing pressure loss and the fluid transportation energy consumption.
另外，重要的是由于其流线型表面，使得形状阻力减小，从而降低了流动压力损失，减少流体输送能耗。

When the shape of a wing creates more lift from the air passing around it than it does drag (air resistance), an aircraft will fly.
