Skeleton structure of telescopic wing

Abstract

The invention discloses a telescopic skeleton structure, and provides a wing scheme with foldable internal wing skeletons, continuously variable wingspans and a large wingspan change range for a variable-span aircraft. The telescopic skeleton structure is composed of a steering engine driving device, a wing rib, a sliding rail beam and motion module units. Each motion module unit comprises eight transmission connecting rods and a connecting structure hinged to the connecting rods. The wing ribs are provided with sliding guide rails and lug-shaped bosses. According to the invention, wing extension and retraction can be realized by only one drive, and the unique wing rib design and motion module unit connection mode can enable the common wing rib to translate along the wingspan direction; the parts of the motion module unit are the same in installation and motion mode and equal in motion distance, and the overall stability is guaranteed to a certain extent. The devices are arranged in the airfoil, so that the aerodynamic performance of the aircraft is not influenced in the stretching and retracting process of the airfoil. The space in the wing can be well compressed, control is simple and stable, the structure is simple, and implementation is easy.

Description

technical field [0001] The invention belongs to the technical field of deformable aircraft, and relates to a skeleton structure of a retractable wing. Background technique [0002] As the product of human beings' continuous pursuit of the excellent flight ability of birds, the deformable aircraft can obtain the best aerodynamic efficiency by changing its shape in different flying environments. The variable wings improve the comprehensive ability of the aircraft, enabling the aircraft to Adapt to more complex and changeable mission environments. [0003] Fixed high-aspect-ratio wings have advantages in terms of fuel efficiency, but poor maneuverability and relatively low cruising speeds. Conversely, aircraft with low aspect ratio wings are faster and more maneuverable, but less aerodynamically efficient. Aircraft with retractable wings have the potential to take advantage of all aspects of the configuration, which is an important direction for the future research and develo...
