Flying toy configured to move by wing flapping

Abstract

A flying toy capable of moving by flapping of wings includes an actuation mechanism, for the wings, comprising a crank drive rotated by a means providing the driving force, two flexible wings arranged symmetrically with respect to the vertical plane of symmetry of the toy and connected, at the wing bases, to the actuation mechanism. The wing bases are mounted oscillating about axes arranged on both sides of the vertical plane of symmetry of the toy. The toy includes a control means, that receives a control signal indicating a left turn, increases the tension on the right wing and reduces it on the left wing. For a right turn, the opposite action is performed.

AI Technical Summary

Benefits of technology

This patent describes a method for controlling a flying toy that moves by flapping its wings. The toy has a support structure and an actuation mechanism with a rotating crank drive. It also has two flexible wings that move symmetrically with respect to the toy's vertical plane of symmetry. The wings' posterior edges are connected to a memory shape wire that constricts when it receives an electric current. The method involves receiving a control signal and constricting the memory shape wire connected to the right or left wing to reduce tension on that wing for a right or left turn, respectively. The technical effect of this patent is a more precise and responsive control of the flying toy's movement by flapping its wings.

Problems solved by technology

The wings of this toy have airfoil surfaces that have an increased drag when the angle of incidence increases.

In practice, this technique does not enable turning of the toy with great precision.
