Scheme for improving flapping intensity of flapping-wing aircrafts

Abstract

The invention relates to an aircraft in fluid media (air or water), particularly to a scheme for improving the flapping intensity of flapping-wing aircrafts. The breakthrough on miniature flapping-wing aircrafts is realized, and however, except miniature flapping-wing aircrafts, high-efficient manned flight cannot be realized so far due to the rigorous requirements for materials. In order to improve the flapping intensity of flapping-wing aircrafts, the invention provides the scheme for improving the flapping intensity of flapping-wing aircrafts. The flapping-wing aircraft comprises an aircraft body, flapping wings, and a flapping mechanism, wherein each flapping wing consists of a wing bar and a wing membrane, and each wing membrane is attached to the corresponding wing bar; the flapping mechanism consists of double-crank hinge mechanisms, usually, the flapping wings of a flapping-wing aircraft or an insect are connected with bodies through one position (usually called wing root), and due to the low intensity of materials, artificial flapping-wing aircrafts cannot realize manned flight. The scheme provided by the invention has the benefits that at least two positions of each flapping wing are connected with the aircraft bodies through the double-crank mechanisms, so that the requirements for the intensity of the materials of the flapping wings are substantially reduced; motors mounted on the aircraft bodies enable the flapping wings to vibrate through the double-crank mechanisms, so that the high-efficient flight of the flapping-wing aircraft is realized.

Description

Technical field [0001] The invention relates to an aircraft in a fluid medium (air or water), in particular to a scheme for improving the flapping strength of an aircraft with flapping wings. Background technique [0002] At present, in order to achieve high-efficiency flight (such as the flight of dragonflies), the existing flapping-wing aircraft are all pursuing high-frequency and low-amplitude flapping wings. Breakthroughs have been achieved in miniature flapping-wing aircraft. Due to the extremely stringent requirements of materials, efficient manned flight cannot be realized so far. The manned wing flapping machine is still in the stage of model making and conception, and cannot be really put into practical use. Contents of the invention [0003] In order to improve the strength of the wings of the flapping aircraft and make the artificial wing flapping aircraft have the energy efficiency approaching the navigation of insects, the present invention provides a scheme ...
