<p>A method of forming a plurality of large diameter tubular titanium components each suitable for use as a portion of a jet engine exhaust tube, the method includes the step of forming a large diameter titanium tube (1), and then subjecting the tube to a superplastic forming process. The superplastically formed titanium tube is then cut at at least one selected location (14, 15) along its length to sever it into at least two large diameter tubular titanium components (11, 12, 13). The titanium components (11, 12, 13) are particularly suitable for assembly to form an adjustable exhaust jet pipe for a VTOL aircraft.</p> |
