Large aspect ratio wing structure capable of lateral assembly and assembly method thereof

Abstract

The invention discloses a transversely assembled wing structure with the high aspect ratio and an assembly method of the wing structure. The wing structure comprises a front edge assembly, a wing beam assembly and a rear edge assembly, wherein the front edge assembly comprises a longitudinal front wall, a front edge wing rib group and a front edge skin; the front edge wing rib group comprises a plurality of front edge wing ribs which are longitudinally arranged in parallel; each front edge wing rib is fixedly connected to a longitudinal front wall; the front edge skin is connected to the periphery of the front edge wing rib group; the wing beam assembly comprises a longitudinal wing beam group, a reinforced wing rib group, an upper skin and a lower skin; the longitudinal wing beam group comprises a plurality of longitudinal wing beams which are transversely arranged in parallel; the reinforced wing rib group comprises a plurality of reinforced wing ribs which are longitudinally arranged in parallel; the reinforced wing rib group is fixedly connected to the longitudinal wing beam group; the upper skin is connected to the upper side of the reinforced wing rib group; the lower skin is connected to the lower side of the reinforced wing rib group; and the rear edge assembly comprises a longitudinal rear wall, a rear edge wing rib group and a rear edge skin. The transversely assembled wing structure has the excellent mechanical property, and is high in disassembling efficiency, small in space occupied for transportation, and convenient to transport.

Description

technical field [0001] The invention relates to a horizontally assembled large-aspect-ratio wing structure and an assembly method thereof, which belong to the technical field of aerospace. Background technique [0002] At present, wings are the main components of fixed-wing aircraft, which support the aircraft to fly in the air by generating lift. For modern solar-powered aircraft, in order to increase the area of ​​the wing-covered solar panels and improve the endurance, the wingspan can reach more than 50 meters. Wing structure with high aspect ratio. At the beginning of the design, the designer needs to specially consider the effectiveness and feasibility of disassembly and transportation of such a large-aspect-ratio aircraft wing. Wing transportation is the most important and complicated problem in the transportation of large aircraft parts. At present, the wings of individual large and medium-sized aircraft in China need to be transported over long distances. Large p...

AI Technical Summary

Problems solved by technology

[0004] 1. For the wing structure of traditional manned aircraft, the load-bearing structure of the group should be metal aviation aluminum alloy, or even titanium alloy. Although the strength and rigidity are high, the weight is heavy and the fuel consumption is large, so it is not suitable for advanced low-load high-altitude long-distance flight when flying drones;

[0005] 2. For a wing structure with a large aspect ratio, if it is divided longitudinally into several wing module sections, the main load-bearing spar will be divided into several parts, resulting in a reduction in the load-bearing effect; on the other hand, as the aspect ratio increases, the Wing flexibility continues to increase, and the number of modules is too large, which will lead to a decrease in the overall stability of the wing, which is prone to wing instability and damage accidents, reducing the service life of the wing;

[0006] 3. When carrying out long-distance transportation, too many modules will lead to difficulties in disassembly and transportation, and reduce the efficiency of disassembly and transportation
