有效迎角的减小又使得弹性机翼的有效气动力载荷减小。
The torsion reduces the effectual attack angle of the elastic sweep wing.
她的座椅下面有个轨道，因此座椅可以前后滑动，这样在桨入水时可以增大它们的迎角，使每一次划船时桨在水中停留的时间更长，从而更有效率。
Her seat slides forward and back on tracks in the center of the cockpit, which increases the OARS 'Angle of attack as they enter the water — making each stroke longer and more efficient.
当扑翼在小迎角飞行时，机翼带翼刀可以有效地改善扑翼的气动特性。
When flapping-wing flight at small attack Angle, wing had wing-blade improve effectively aerodynamic characteristic of flapping-wing.
通过风洞试验，对带升降副翼控制的自由翼气动特性也进行了实验研究，验证了位于自由翼后缘的升降副翼可有效地控制自由翼相对气流的平衡迎角。
The aerodynamic characteristics of the free wing are investigated in this paper. The wind tunnel test results shows that the control of the angle of attack of the fre…
