All of the aerodynamic force must be produced in the absence of any incident flow, meaning lift can only be produced by the powered reciprocating motion of the wing.

所有的空气动力都必须在缺乏任何迎流的情况下产生，意味着只可能通过翼的有动力作用的往复运动来产生提升。

By contrasting the computed aerodynamic force of flexible flapping-wing and rigid wing, it is found that if the flexibility is controlled suitable, it can enlarge the lift and thrust effectively.

通过计算分析柔性扑翼的气动特性发现，控制适当的话，柔性变形能大大改善扑翼的气动性能。
