<p>A method of producing an engine wall structure that comprises an inner wall (3), to which hot gas is admitted during engine operation, an outer wall (4), which is colder than the inner wall (3) during engine operation, and at least two webs (5) that connect the inner wall (3) with the outer wall (4) and delimit a cooling duct (6) between said walls (3, 4). The engine wall structure is produced by wire-electro discharge machining the duct (6) out of a solid sheet (11) forming the entire engine wall structure including the inner wall (3), the outer wall (4) and the webs (5).</p> |
