Embodiment Construction

[0023] Now, example embodiments will be described below with reference to the accompanying drawings.

[0024] Exemplary embodiments of the present invention will be described below by way of example only. An example of a double-skin structure including an internal corrugated or grid-like structure is described. In the following description, figure 1 -5 for describing manufacture figure 1 with 2 Scheme of the example artifact shown. Figure 6-9 Then it is used to describe a specific example in the form of an airfoil structure, especially a winglet. It should be noted, however, that the present invention is not limited to the particular article illustrated and its manner of manufacture, but may be applied to a variety of other articles including dual-skin constructions.

[0025] The article of manufacture example embodiments are described as including a dual skin structure including a first skin, a second skin, and an intermediate structure. The intermediate structure incl...

Abstract

A dual-skin structure comprises a first skin, a second skin and an intermediate structure. The intermediate structure comprises a plurality of first contact portions connected to an interior surface of the first skin, a plurality of second contact portions connected to an interior surface of the second skin and a plurality of interconnecting web portions integral to the first and second contact portions and extending between ones of the first and second contact portions to form an internal supporting structure alternating between the interior surfaces of the first and second skins.

Description

technical field [0001] The present invention relates to a manufactured article (hereinafter referred to as article) comprising a double-skin structure and to a method of manufacturing such an article. Such manufactured parts with such structures can be used, for example, in the aviation and aerospace industry. Background technique [0002] Double-skin constructions are used in different applications. For example, a typical fuselage design for an airfoil structure includes a substantially double-skin structure formed from individual monolithic components. The upper and lower skins provide a smooth interface with the airflow surface. In known fuselage designs, the upper and lower skins are usually spaced apart from each other and joined together by structural members, usually channel steel structures called spars, extending along the span (the length of the wing) direction extension. The function of the spar is to maintain the aerodynamic profile of the wing, to account fo...
