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.

What is claimed is: 1. A method of creating a truss-like primary support structure as an integrally formed, single piece component for use in an airborne mobile platform, the method comprising: providing a mold for receiving a quantity of flowable titanium, the mold being adapted to form a truss-like structure having a plurality of independent, interconnected truss elements and a plurality of nodes where said truss elements intersect, at least one portion enabling the truss-like structure to be secured to a portion of the airborne mobile platform; heating a quantity of titanium to a temperature to produce a flowable titanium; filling the mold with said flowable titanium; allowing the mold to cool; and removing the truss-like structure from the mold. 2. The method of claim 1, further comprising forming the truss elements with a circular shaped cross section. 3. The method of claim 1, further comprising forming the truss elements with a rounded, quadrilateral shaped cross section. 4. The method of claim 1, wherein the truss elements are arranged, analyzed and sized with a plurality of spaced apart interconnecting nodes so that a structural integrity of the truss-like structure is not destroyed in the event of a failure of any one of said truss elements. 5. The method of claim 1, wherein the mold is used to form a truss-like structure comprising a strut for securing a jet engine to a wing of an aircraft. 6. A method of creating a truss structure as an integrally formed, single piece component for use as a load supporting component for a mobile platform, the method comprising: providing a mold for receiving a quantity of flowable titanium, the mold being adapted to form a monolithic truss structure having a plurality of independent, interconnected truss elements and a plurality of nodes where said truss elements intersect, at least one portion enabling the monolithic truss structure to be secured to a portion of a mobile platform; using the mold to selectively form portions of said truss structures with a first thickness and portions with a second thickness that is greater than said first thickness; heating a quantity of titanium to a temperature to produce a flowable titanium; filling the mold with said flowable titanium; allowing the mold to cool; removing the monolithic truss structure from the mold; and machining the portions of the monolithic truss structure having said second thickness to form structural elements for attaching said monolithic truss structure to said mobile platform and to a component supported from said mobile platform. 7. The method of claim 6, further comprising forming the truss elements with a circular shaped cross section. 8. The method of claim 6, further comprising forming the truss elements with a rounded quadrilateral shaped cross section. 9. The method of claim 6, wherein forming the monolithic truss structure comprises forming at least one portion thereof suitable for enabling the monolithic truss structure to be secured to an aircraft engine. 10. A method for forming a primary aircraft structure suitable for use in constructing a commercial passenger aircraft, the method comprising: forming a monolithic truss through a casting process as a single piece component, the truss being formed from a titanium alloy; further forming the truss with a plurality of truss elements, the truss elements intersecting at a plurality of nodes, the nodes and truss elements being arranged in a manner that enables a structural integrity of the truss to be maintained in the event of a failure of one of the truss elements; and further forming the truss with at least one attachment point suitable for securing the truss to a portion of an aircraft structure. 11. The method of claim 10, further comprising forming the monolithic truss with at least one attachment point for securing to an engine of said aircraft. 12. The method of claim 10, further comprising forming the monolithic truss with dimensions and strength suitable for supporting a jet engine from a wing of said aircraft. 13. The method of claim 10, further comprising forming the truss elements with a rounded quadrilateral shaped cross section. 14. The method of claim 10, further comprising forming the truss elements with a circular shaped cross section. 15. The method of claim 10, further comprising forming the truss from a titanium alloy Ti-6AL-4V.
