Claims12
A method of manufacturing wall structure for a rocket engine nozzle comprising the steps of
- providing a workpiece with a cylindrical shape having a circular cross section which cross section diameter varies in an axial direction of the workpiece,
- producing a plurality of spaced elongated webs in the workpiece by feeding a machining tool along the workpiece, wherein the plurality of spaced elongated webs are produced by indexing the machine tool in relation to the workpiece, wherein the webs are produced so that they extend in a diverging manner from a first end of the work piece to a second end of the work piece and are distributed around a circumference of the workpiece, wherein in a step of producing one elongated web the machining tool simultaneously machines to first side surface of the web, a second side surface of the web and a top surface of the web.
