The function of the alula on engineered wings: a detailed experimental investigation of a bioinspired leading-edge device.

abstract：:Flight initiation is fundamental for survival, escape from predators and lifting payload from one place to another in biological fliers and can be broadly classified into jumping and non-jumping takeoffs. During jumping takeoffs, the legs generate most of the initial impulse. Whereas the wings generate most of the for...
