A folding variant wing and aircraft driven by sarrus structure

Abstract

The invention discloses a folding variant wing based on Sarrus structure driving. The folding variant wing comprises a fuselage connection driving module, a wing body and a folding connection device based on a Sarrus structure; the wing body comprises an inner wing, a middle wing and an outer wing; one end of the folding connection device is connected with the fuselage connection driving module, and the other end of the folding connection device is connected with the outer wing and said parts are arranged on the folding connection device. According to the invention, the foldable three-sectiontype variant wing is realized; the folding is realized on the basis of a Sarrus structure; the inner wing and the middle wing can be folded triangularly, meanwhile, the whole outer wing keeps horizontal with the aircraft body, translation is achieved in the wingspan direction, the overall space of the variant wing is well compressed, and the overall stability is improved to a certain extent; the variant wing can be used for a cross-medium aircraft, and the shape of the wing can be flexibly changed according to actual needs.

Description

technical field [0001] The invention relates to aircraft wings, in particular to a folding variant wing driven by a Sarrus structure and an aircraft. Background technique [0002] In order to change the single operating environment and performance of traditional aircraft, and make full use of the high-speed and high-maneuverability of aerial vehicles and the good concealment of underwater vehicles, aviation researchers from all over the world are committed to researching a cross-sea vehicle with high adaptability to water and air amphibiousness. medium craft. According to the different working methods and media interaction motion forms, water-air amphibious cross-media vehicles are divided into three categories: water-based drones, submarine-launched drones, and diving drones. Since the density of water is more than 800 times that of air, and the viscosity coefficient is 59 times that of air, the shapes of aircraft and submersibles are quite different. A better solution is ...

Problems solved by technology

Due to the huge difference in physical properties between water and air, when the aircraft splashes into the water, the sudden change of the moving medium will produce a large impact force, which requires high structural strength of the trans-medium aircraft, and the large change of the sweep angle of the swept-wing aircraft is easy. The change of the aerodynamic center will have a negative impact on flight stability. Therefore, designing a high-strength lateral folding variant aircraft has become a key technical problem to be solved urgently.
