Definitions

  • the combustion chamber shingle has a base body on which at least one edge area is provided.
  • This edge area is designed in the form of an edge strip which extends essentially to the surface of the base body.
  • the edge strip has a thickness which differs from the thickness of the base body.
  • the edge strip is usually designed with a greater thickness than the base body itself.
  • the plate-shaped component according to the invention can be optimized with regard to cooling.
  • the additive manufacturing process makes it possible to design the cooling holes differently over their length, for example to change the cross section. All of this means that a sufficient volume of cooling air can be directed to the rear side of the base body of the plate-shaped component opposite the edge strip.
  • the possibility of making the cooling holes variable in their longitudinal extent also makes it possible to implement curved or coiled or meandering shapes of cooling air holes. This leads to more effective cooling.
  • the recess is formed symmetrically to the central plane of the cooling air hole. This results in uniform stress distributions in the area of the recess and the adjacent areas of the support body. Furthermore, the supply of the cooling air into the cooling air hole is optimized.
  • An edge strip 2 which has a thickness d2, is formed in one piece with it on the edge region of the base body 1.
  • the thickness d1 is measured from the surface 6 of the base body 1 to its rear side.
  • the thickness d2 of the edge strip 2 is defined in the same direction.
  • Both the straight-line wall courses 7 with the lengths l1 and l2 and the rounded wall courses 8 with the radii r1 and r2 are not absolutely necessary for the invention; other wall courses can also be realized in order to form the recess 4.
  • the lengths l1 and l2 as well as the radii r1 and r2 can differ from one another in the specified intervals. It is also not absolutely necessary for the recess 4 to be arranged symmetrically with respect to a central plane of the cooling air hole 5.
  • the component according to the invention is usually produced by an additive method with the base body 1 being aligned vertically. If this is provided with an edge strip on all sides, an edge strip with the thickness d2 is first built up. The transition to the base body 1 with a thickness d1 takes place continuously through the respective support body 3, which is provided with the recesses 4.
