An engine wall structure includes an inner wall to which hot gas is admitted during engine operation, an outer wall, which is colder than the inner wall during engine operation, and at least two webs that connect the inner wall with the outer wall and delimit a cooling duct between the walls. The webs are mainly formed by a first material and the inner wall is mainly formed by a second material of other composition and other heat conductivity than the first material.

The invention claimed is: 1. A method of producing an engine wall structure that comprises an inner wall, to which hot gas is admitted during engine operation, an outer wall, which is colder than the inner wall during engine operation, and at least two webs that connect the inner wall with the outer wall and delimit a cooling duct between the walls, comprising forming the webs by masking the inner wall and depositing a first material onto unmasked portions of the inner wall, the inner wall mainly comprising a second material of other composition and other heat conductivity than the first material. 2. A method according to claim 1, wherein, subsequent to the formation of the webs, the outer wall is attached to the webs. 3. A method according to claim 1, wherein the outer wall is connected to the webs by means of a metal fusion operation. 4. A method according to claim 3, wherein the metal fusion operation is a welding operation. 5. A method according claim 1, wherein the composition of the material of the webs is substantially equal to the composition of the material of the outer wall. 6. A method according to claim 1, wherein the material of the inner wall has higher heat conductivity than the material used for the webs. 7. A method of producing an engine wall structure that comprises an inner wall, to which hot gas is admitted during engine operation, an outer wall, which is colder than the inner wall during engine operation, and at least two webs that connect the inner wall with the outer wall and delimit a cooling duct between the walls, comprising forming the webs by deposition of a first material onto the inner wall, the inner wall mainly comprising a second material of other composition and other heat conductivity than the first material, wherein the inner wall comprises a copper or a copper-based alloy, and the webs comprise steel. 8. A method according to claim 1, wherein the material of the inner wall has a higher temperature resistance than the material of the webs. 9. A method according to claim 1, wherein the material of the webs has higher heat conductivity than the material of the inner wall. 10. A method of producing an engine wall structure that comprises an inner wall, to which hot gas is admitted during engine operation, an outer wall, which is colder than the inner wall during engine operation, and at least two webs that connect the inner wall with the outer wall and delimit a cooling duct between the walls, comprising forming the webs by deposition of a first material onto the inner wall, the inner wall mainly comprising a second material of other composition and other heat conductivity than the first material, wherein the material of the webs has higher heat conductivity than the material of the inner wall, wherein the inner wall comprises steel and the webs comprise aluminum or an aluminum-based alloy. 11. A method according to claim 1, wherein the material of the outer wall and the material of the webs have corresponding heat conductivity properties. 12. A method according to claim 1, wherein the material of the outer wall and the material of the webs have corresponding properties as to their mechanical strength. 13. A method according to claim 1, wherein a height of the webs is adjusted by a machining operation before the outer wall is attached thereto. 14. A method according to claim 1, wherein the metal deposition is performed by electro-deposition.
