Abstract

The invention discloses a deformed wing with variable camber driven by a connecting rod, which comprises a wing body, a connecting rod driving assembly and a rotating shaft connection assembly. The wing body is composed of multiple wing modules, and the wing modules pass through the rotating shaft once. The connecting components are rotationally connected, and the connecting rod driving component organically combines each wing module, so that each wing module can form a knuckle-like curvature deformation under the drive of linear motion. The connecting rod driving component adopted has high driving efficiency and can realize Wing deformation in a wide range of camber.

Description

technical field [0001] The invention belongs to the technical field of aerospace equipment and relates to a wing structure, in particular to a deformed wing with variable camber driven by a connecting rod. Background technique [0002] The wing is a key component that determines the overall aerodynamics of the aircraft, and its shape has an important impact on the overall performance of the aircraft. Under different flight environments and missions, changing the aerodynamic shape of the wing itself according to the actual situation can change the performance parameters of the aircraft such as lift-to-drag ratio, take-off and landing distance, fuel consumption, range, maneuverability and stealth, so that the aircraft can fly in the air. Maintain the best overall performance in the process. [0003] Due to the various advantages of the deformed wing, a large amount of research work has been carried out abroad since the last century. Since the end of World War II, the United ...
