Abstract
Method and arrangement for providing a liquid fuel rocket engine member (10). The member has a load bearing wall structure (14) having a plurality of cooling channels (11). For improving the heat transfer, a material with a higher thermal conductivity than the load bearing wall structure (14) is applied to the wall structure.
Claims18
A liquid fuel rocket engine member (10) comprising:
- a load bearing wall structure (14, 15) including a plurality of cooling channels (11), wherein the outside of the wall structure includes a curved sheet metal wall (14) and wherein the cooling channels (11) are longitudinally attached to the sheet metal wall;
- and
- a material with a higher thermal conductivity than the load bearing wall structure (14, 15) has been applied to said wall structure, that the material (17) is arranged in contact with the sheet metal wall (14), that the material forms a substantially continuous contact surface against the sheet metal wall (14) from the wall of one cooling channel to the wall of an adjacent cooling channel and that the material (17) at least partly surrounds the walls of the cooling channels (11).
A method for manufacturing a liquid fuel rocket engine member (10) comprising:
- arranging a plurality of cooling channels (15) adjacent to each other for at least partly forming a wall structure of the member, wherein the cooling channels (11) are longitudinally attached to a curved sheet metal wall (14) on the inside of the same, thereby forming said wall structure;
- and
- applying a material (17) with a higher thermal conductivity than the material of the wall structure (14, 15) to said wall structure so that the material (17) is applied between the cooling channels (11), that the material (17) is arranged in contact with the walls of two adjacent cooling channels (15) forming a connection between them and that the material (17) at least partly surrounds the walls of the cooling channels (11).
