Component having a box structure for an airplane airfoil

摘要

The present invention relates to a panel, especially for a component having a box structure in an airplane airfoil, comprising a surface shaped body and grid-like reinforcement bars protruding from the body on one side of the body, and the body and the grid-like reinforcement bars are integral molded. Since the body and the grid-like reinforcement bars of the panel are integral molded, no additional connecting process is required, so that the disconnection phenomenon as happened between the skin and the stiffener or stringer of the prior art would not occur, and the assembly complexity can be decreased.

主权项

1. A component having a box structure for an airplane airfoil, comprising a plurality of C-profiles, the plurality of C-profiles each consist of a connecting portion, two legs and an opening end, wherein the connecting portion is opposite to the opening end, and the two legs respectively extend from the connecting portion to the opening end, the plurality of C-profiles being subsequently inserted into one another, wherein one of the C-profiles with its connecting portion is inserted into an opening end of another adjacent one of the C-profile and is fixed thereto in the region of being inserted into one another.
