Embodiment

[0039]In view of the above requirements, the present invention relates to a retractable elastic wing, which includes a wing connecting plate, a wing short plate, a wing long plate, a plurality of wing connecting rods, ribs, thin wings, upper and lower covering wings, through the shaft hole Combination of connections. Among them, the wing connecting plate, wing short plate, wing long plate, multiple wing connecting rods, and wing ribs are combined with each other in the form of a planar four-bar linkage, and are interrelated and constrained. Think of all the mechanisms that make up the four-bar linkage as a quadrilateral. To complete the two diagonal angles, the opening becomes larger and the distance between the vertices becomes smaller, and the other two diagonal angles are reduced and the distance between the vertices becomes larger. , it is necessary to satisfy the condition that the total lengths of the two sides that form two diagonal angles are equal to each other. For ...

Abstract

The invention relates to a foldable and unfoldable elastic wing in the field of aircrafts. The Foldable and unfoldable elastic wing comprises a wing connecting plate, a wing short plate, a wing long plate, a wing connecting rod, a wing rib, a thin wing sheet, an upper covering wing sheet and a lower covering swing sheet connected through axle holes; the wing connecting plate, the wing short plate,the wing long plate, the wing connecting rod and the wing rib are combined in a form of a planar four-connecting rod mechanism, the wing connecting plate is connected to a wing driving mechanism, thewing driving mechanism inputs a reciprocating thrust to push the wing short plate to swing around the axis, the wing short plate drives the a plurality of planar four-connecting rod mechanisms composed of the wing long plate, the wing connecting rod and the wing rib so as to fold and unfold the wing. The resistance of the wing lifted up in a flapping wing flying process can be reduced to the maximum extent, and meanwhile, the wing storage space can be saved to the maximum extent when an aircraft is parked.

Description

technical field [0001] The invention relates to the field of equipment suitable for flapping wings and fixed-wing aircraft, in particular to a retractable elastic wing. Background technique [0002] The flapping wing aircraft is a kind of aircraft that can fly by flapping its wings up and down. In the current existing aircraft, it is generally impossible to solve the downward reaction force brought by the wings when they are raised, so that the aircraft During the flight, the body fluctuated up and down, which caused the fuselage to vibrate. Cannot fly as smoothly and nimbly as a bird. To solve this problem, the wing needs to be able to fold and unfold during flight like a bird's wing. It cannot eliminate the up and down fluctuation and fuselage vibration during flight. This is a major factor hindering the development and progress of flapping wing aircraft in the practical and aviation industry. The main reason is that there is no practical wing that can be folded. and un...
