Abstract
Method and arrangement for providing a liquid fuel rocket engine member having a load bearing wall structure (11,14) including a plurality of cooling channels (11) for handling a coolant flow. Each cooling channel (11) is provided with a flow guiding surface (15) extending at an angle to the cooling channel axis, for providing the axial coolant flow with an added flow component in the radial direction.
Claims10
A liquid fuel rocket engine member (10) comprising:
- a load bearing wall structure (11, 14) comprising a plurality of cooling channels (11) for handling a coolant flow, wherein the load bearing wall structure (11,14) comprises a curved wall (14), and wherein a wall of each of said cooling channels is attached to said curved wall;
- and
- each of the cooling channel (11) having a flow guiding surface (15,16,17,19) extending at an angle to the cooling channel axis for providing the axial coolant flow with an added radial directional flow component.
A method for manufacturing a liquid fuel rocket engine member (10) having a load bearing wall structure (11, 14) comprising a plurality of cooling channels (11) for handling a coolant flow, said method comprising:
- shaping a sheet metal surface to provide a flow guiding surface (15);
- folding the sheet metal into cooling channels (11);
- and
- forming said wall structure by at least said folded sheet metals by attaching said folded sheet metals to a wall (14) and thereby forming said wall structure.
