Driving unit of bird tail-imitating unfolding mechanism

Abstract

The invention discloses a driving unit of a bird tail-imitating unfolding mechanism, which belongs to the technical field of driving of flexible structures. A paper folding pipe flexible structure driving device drives a distance adjusting device to contract at equal intervals through inflation of an inflation pipe, adjacent pulse pipes are deflected, and therefore tail wing unfolding is achieved; when the inflation pipe is deflated, the driving device shrinks, the driving force is reduced, and the distance adjusting device extends at equal intervals, so that the adjacent pulse pipes return to a parallel arrangement state, namely the tail wings are closed. The driving unit is compact in structure, sufficient in movement stroke, small in size and light in weight.

Description

technical field [0001] The invention belongs to the technical field of driving of flexible structures, and in particular relates to a driving unit of an imitation bird unfolding mechanism. Background technique [0002] The bird-like flapping-wing aircraft is an aircraft that imitates birds. Its propulsion, lifting and hovering systems all rely on the flapping-wing mechanism. Compared with fixed-wing and rotary-wing, it has better maneuverability. At present, all countries have launched research on the bird-like flapping wing aircraft, but the design of the empennage still needs to be innovated. When birds fly, the tail feathers are close together, and when hovering or landing, the tail wings are unfolded to maintain balance. Therefore, the bird-like aircraft requires that the tail wings can independently drive the feathers to expand and retract. [0003] The tail of the bird-like aircraft generally adopts fan-shaped deployment, and the initial shape is the feathers arranged...
