Abstract
Official abstract text for this publication.
A central airfoil box comprising two beams, each beam having a wall pierced with a first bore centered on a first axis, a connecting rod comprising, for each wall, a yoke joint having two flanks arranged on either side of the wall and pierced with a bore. Each yoke joint is fixed to the wall by a fixing system. The fixing system comprises a bearing lodging in the first bore, and being pierced with a second bore centered on a second axis parallel and offset to the first axis, a cylindrical shoulder, secured to and coaxial with the bearing and bearing against the wall, an outer perimeter of the shoulder having a plurality of splines, at least one block fixed to the wall around the first bore and configured to lodge in one of the splines, and a shaft lodging in the second bore and the yoke joint bores.
First claim
Opening claim text (preview).
The invention claimed is: 1. A central airfoil box comprising: two beams, each beam having a wall pierced with a first bore centered on a first axis, a connecting rod comprising, for each wall, a yoke joint having two flanks arranged on either side of the wall and pierced with a bore, and in which each yoke joint is fixed to the wall by a fixing system, at least one of the fixing systems comprising an anchoring system which comprises: a bearing lodging in the first bore, and being pierced with a second bore centered on a second axis parallel to said first axis and offset relative to said first axis, a cylindrical shoulder, secured to and coaxial with the bearing and configured to come to bear against the wall, an outer perimeter of the shoulder having a plurality of splines, at least one block fixed to the wall around the first bore and configured to lodge in one of the splines, and a shaft lodging in the second bore and the bores of the yoke joint. 2. The central airfoil box according to claim 1 , wherein each spline is formed as an outwardly open half-cylinder whose axis is parallel to the first axis and wherein each block is formed as a cylinder whose diameter is equal to the diameter of the splines and whose axis is parallel to the first axis. 3. An aircraft comprising a central airfoil box according to claim 1 .
