Deformation biplane

Abstract

The invention provides a deformation biplane, and belongs to the technical field of airplanes. The deformation biplane comprises a plane body, upper wings, lower wings and an empennage, wherein a control device and a power device are arranged in the body; the empennage is positioned at the tail of the plane body; the upper wings are similar to conventional wings and are symmetrically distributed on the left side and the right side of the upper end of the plane body; the lower wings are symmetrically distributed on the left side and the right side of the lower end of the plane body; and each lower wing comprises a retractable rod, a folding wing rib, a flexible skin and a retracting device. A plurality of small wing ribs are arranged on each folding wing rib; small holes are separately formed in the small wing ribs, and each folding wing rib is serially connected to the corresponding retractable rod through the corresponding small holes; each flexible skin is divided into two parts, andone part of each flexible skin wraps the corresponding folding wing rib while the other part of each flexible skin is rolled in the retracting device; the roots of the lower wings are fixed by the retracting devices; the retractable rods and the retracting devices are adjusted through a control device; and when the biplane flies in air, a biplane mode and a monoplane mode of the biplane can be switched. The deformation biplane is simple in structure, advantages of a monoplane and advantages of a biplane are combined, the flying efficiency is high, and the deformation biplane is multipurpose.

Description

technical field [0001] A deformable biplane belongs to the technical field of aircraft, and in particular relates to a biplane. Background technique [0002] Traditional monoplanes are difficult to achieve short-distance take-off and landing, and the critical stall angle of the wing is small, so it is easy to stall, so it is not suitable for large [0003] Angle flight; traditional biplanes have low wing efficiency and poor stability when cruising; the wing is the main part of the aircraft that can be reconfigured in flight. Purposefully changing the wing shape in flight can effectively increase the efficiency of the wing. Among them, the effect of changing the wingspan and wing area is the most prominent. Contents of the invention [0004] The purpose of the present invention is to provide a kind of aircraft that can switch between monoplane and biplane parts. [0005] A deformed biplane, comprising a body, an upper wing, a lower wing and an empennage; the body is equi...
