Problems solved by technology

Due to aerodynamic heating, the airfoil structure of the aircraft is subjected to severe force-thermal coupling during the hypersonic aircraft in the atmosphere. Conventional aviation materials such as aluminum alloys have low temperature resistance, which leads to a heavy burden on the heat protection system. At the same time, the metal materials The large coefficient of thermal expansion makes it difficult to match the deformation of the heat protection system, which seriously affects the overall performance of the aircraft. Therefore, it is imminent to design a wing structure that can adapt to repeated use and meet the requirements of hypersonic flight through the atmosphere.

Embodiment Construction

[0032] Below in conjunction with accompanying drawing and specific embodiment the present invention is described in further detail:

[0033] Such as figure 1 Shown is the schematic diagram of the shape of the aircraft wing of the present invention. It can be seen from the figure that the aircraft that shuttles to and from the atmosphere adopts a plane-symmetric shape, and the all-composite co-cured molding wings 2 are symmetrically distributed on both sides of the fuselage along the symmetry plane of the fuselage 1.

[0034] The present invention is suitable for the structural layout of aircraft wings that shuttle back and forth in the atmosphere, in the form of skeleton structure and full-height honeycomb 12 filling, and realizes assembly with the upper and lower skins by means of co-curing, eliminating the number of structural openings caused by traditional mechanical connections More damage to the structure, greatly reducing the number of fasteners and reducing the weight o...

Abstract

The invention relates to an aircraft wing suitable for shuttling back and forth aerosphere, and the aircraft wing includes a skeleton structure and skin, wherein the skeleton structure is formed by intersection of longitudinal beams and transverse ribs, the longitudinal beams comprise a front beam, a main beam and a back beam, the transverse ribs comprise a root rib, a second rib and an end rib; the end of the front beam, near the root rib, is connected with body by a first shear pin; the end of the back beam, near the root rib, is connected with the body by a second shear pin; one end of the main beam stands out of a wing contour envelope and extends into the interior of the body; an end face of one end of the main beam and a body symmetrical plane are flush, the end face of one end of the main beam is adhered to, fixed and connected to an end face of one end of a main beam of a wing at the other side, wherein the end of the main beam of the wing at the other side extends into the interior of the body; the main beam is connected, at the position of the root rib, with a ventral shield of a body internal frame by a third shear pin; a cavity of the skeleton structure is filled with honeycomb, and the skeleton structure and the skin are in co curing connection, the wing structural layout is simple, fastener use amount is less, the weight is light, and the whole wing assembly molding can be realized by overall co curing way.

Description

technical field [0001] The invention relates to a lightweight, high-temperature-resistant, high-rigidity airfoil suitable for aircraft, in particular to an aircraft wing suitable for shuttles to and from the atmosphere, and belongs to the field of aircraft structure design. Background technique [0002] In recent years, with the development of space technology, human eyes have gradually turned to the distant space. In recent decades, various aircraft have shuttled through the atmosphere, and space activities have become increasingly frequent. However, existing aircraft can only be used once, which is expensive. The cost limits the further application of space technology. Since the launch of the space shuttle, countries have tried to carry out research on aircraft that can repeatedly travel to and from the atmosphere. This type of aircraft has the ability to fly in both the atmosphere and the outer environment. Therefore, it is required that the wing structure of the aircraft...
