Abstract
A method for manufacturing structural rods to make it easier to manufacture a structural rod for an aircraft and to improve performance. Each rod includes a rod body and two end portions disposed at either end of the rod body along a longitudinal central rod axis, each end portion comprising at least one mounting lug that protrudes from the rod body along the longitudinal axis. The method includes producing a sandwich panel including two skins gripping a cellular inner body, at least one of the two outer skins having a skin extension for forming a part of the at least one mounting lug of at least one of the two end portions of the rod, and cutting the panel along parallel cutting lines to obtain the structural rods.
Claims15
A method for manufacturing a plurality of structural rods, the method comprising:
- providing a cellular inner body;
- arranging two outer skins on opposing sides of the cellular inner body to form a sandwich panel;
- and
- cutting the sandwich panel along parallel cutting lines, through the cellular inner body and the two outer skins, to produce the plurality of structural rods;
- wherein each of the plurality of structural rods comprises a rod body and two end portions disposed on opposing ends of the rod body along a longitudinal central axis thereof;
- wherein, at each of the two end portions, there are one or more mounting lugs that protrude from the rod body along the longitudinal central axis;
- and
- wherein one or both of the two outer skins have one or more skin extensions, each of which forms a part of one of the one or more mounting lugs of one of the two end portions of each of the plurality of structural rods.
A method for manufacturing a plurality of structural rods, the method comprising:
- providing a cellular inner body;
- arranging two outer skins on opposing sides of the cellular inner body to form a sandwich panel;
- positioning one or more transition pieces at one or both of two opposing ends of the cellular inner body, each of the one or more transition pieces comprising:
- a first part, which is positioned between one of the two outer skins and a chamfer formed at a respective one of the two opposing ends of the cellular inner body, wherein the first part has a thickness that increases as it extends in a direction of the respective one of the two opposing ends to form a first chamfer that is pressed against the chamfer made at the respective one of the two opposing ends of the cellular inner body;
- and
- a second part that extends the first part and is secured to skin extension to form an integral part of an associated mounting lug of one or more mounting lugs with which the second part is associated at the respective one of the two opposing ends of the cellular inner body;
- and
- cutting the sandwich panel along parallel cutting lines, through the cellular inner body and the two outer skins, to produce the plurality of structural rods;
- wherein each of the plurality of structural rods comprises a rod body and two end portions disposed on opposing ends of the rod body along a longitudinal central axis thereof;
- wherein, at each of the two end portions, there are one or more mounting lugs that protrude from the rod body along the longitudinal central axis;
- and
- wherein one or both of the two outer skins have one or more skin extensions, each of which forms a part of one of the one or more mounting lugs of one of the two end portions of each of the plurality of structural rods.
