果蝇调节被动翼俯仰以产生飞行转弯
Fruit flies modulate passive wing pitching to generate in-flight turns
摘要：
飞行的昆虫通过对翅膀运动的微妙操纵来执行空中机动。在这里，我们测量果蝇的自由飞行运动学，并确定他们如何调整他们的翅膀俯仰诱导急转弯。通过分析这些昆虫施加的扭矩俯仰他们的翅膀，我们推断，翅膀铰链作为一个扭转弹簧，被动地抵抗翅膀的倾向，翻转响应空气动力学和惯性力。为了转弯，昆虫不对称地改变弹簧静止角度以产生它们的翅膀的划船运动。因此，昆虫可以产生这些演习，仅使用轻微的主动致动，偏置他们的翅膀运动。
英文摘要：
Flying insects execute aerial maneuvers through subtle manipulations of their wing motions. Here, we measure the free flight kinematics of fruit flies and determine how they modulate their wing pitching to induce sharp turns. By analyzing the torques these insects exert to pitch their wings, we infer that the wing hinge acts as a torsional spring that passively resists the wing's tendency to flip in response to aerodynamic and inertial forces. To turn, the insects asymmetrically change the spring rest angles to generate rowing motions of their wings. Thus, insects can generate these maneuvers using only a slight active actuation that biases their wing motion.
