Furthermore , the requirement of the structure stiffness in piezoelectric actuation plan is lower than the aileron plan .
此外,压电驱动方案对机翼结构刚度的要求低于副翼方案。
When one row on one side blows air at a higher pressure than the other it causes the airflow over the trailing edge on that side to bend up or down , in exactly the way that an aileron would , and the plane rolls accordingly .
