摘要： A truss structure well suited for use as an engine strut on a commercial aircraft. The truss structure is cast as a single piece integrally formed component from a titanium alloy or another suitably lightweight, structurally strong material. The truss structure includes a plurality of integrally formed attachment structures which enable the truss structure to be secured to an element of an aircraft such as a wing. A plurality of attachment areas for an element such as an engine is also formed that allows the element (e.g. jet engine) to be secured to the truss structure. The truss structure includes a plurality of elongated rails and truss elements that are arranged to provide redundant load paths to ensure that a failure of any one truss element or elongated rail will not result in a failure of the overall truss structure to support whatever load is required.
