A winged device to mimic wing movement of insects / hummingbirds

摘要

A winged device comprises an axial support mounted for reciprocating rotary motion about a longitudinal axis of the support, a first wing vane 1 mounted to the axial support 3 for rotation therewith, and a second wing vane 2 hingedly mounted to the axial support 3. The first wing vane 1 is connected by a connector 4, 24 to a cam follower 24 which is constrained to a defined movement path by a cam 23, while the second wing vane 2 is also connected to the cam follower via another connector 5, 25. Through this connection, reciprocation motion of the axial support causes the relative orientation of the wing vanes to change, hence causing flexure / bending of the wing 1, 2. A guide rail and follower may be used in place of the cam and follower mechanism. This ornithopter attempts to mimic the motion of wings of a hummingbird / insect in flight.
