Method of manufacturing a multi-sided formed engine pylon structure
A recently granted patent (Publication Number: US11766828B2) describes a method for manufacturing a multi-sided formed engine pylon structure, which is a component of an aerospace vehicle. The method involves several steps to create a strong and efficient structure.
The first step is to construct a base structure using a specific construction technique. This base structure is then modified by creating one or more fold lines of reduced cross-sectional thickness. These fold lines allow for easier folding of the structure in later steps.
Next, one or more additional features are incorporated into the base structure using an additive manufacturing technique. These additional features, such as stiffening ribs, are designed to physically stiffen the multi-sided formed engine pylon structure, enhancing its strength and durability.
The intermediate structure created with the additional features is then refined to a tolerance in an area that will be located within the internal space defined by the multi-sided formed engine pylon structure. This ensures a precise fit and alignment of the components.
The intermediate structure is then folded along the previously created fold lines to create the multi-sided formed engine pylon structure with two or more sides. During this folding process, at least one of the additional features is located within the internal space of the structure.
To secure the structure, welding is performed along the fold lines between the sides of the multi-sided formed engine pylon structure. This welding ensures a strong and stable connection between the folded sides.
Finally, a closeout element is incorporated into the structure to further define and close the internal space. This element adds an additional layer of protection and stability to the overall structure.
The method described in the patent also allows for the incorporation of separately constructed additional elements, such as a bulkhead, into the intermediate or final structure. This provides flexibility in design and allows for the integration of various components as needed.
Overall, this patented method offers a comprehensive approach to manufacturing a multi-sided formed engine pylon structure for aerospace vehicles. By combining different construction techniques and incorporating additional features, the resulting structure is strong, durable, and efficient.
