METHOD FOR MANUFACTURING REGENERATIVE COOLING PATH FOR LIQUID-FUEL ROCKET ENGINE CHAMBER Russian patent published in 2014 - IPC F02K9/64 

FIELD: transport.

SUBSTANCE: invention relates to rocket engineering, namely - to creation of liquid-fuel rocket engine (LFRE) chambers. Method for manufacturing a regenerative cooling path for a liquid-fuel rocket engine chamber consists in making an exterior and flame sheaths with their subsequent interconnection at vertices of doubletee spacers with formation of cooling channels between them, in this design, the doubletee spacer flanges are made of variable width due to interleaving recesses on them, herewith, low energisers are formed by the mentioned interleaving recesses. Recesses on each flange of the doubletee spacer are made in a staggered order. Recesses on the upper and lower flanges of the doubletee spacer are made in the staggered order. Recesses of adjacent spacers are arranged so that recesses on the flanges of one spacer lay opposite to projections of its adjacent spacer. Recess depth is 25-75% of the flange width. In the vertical walls of the doubletee spacers through channels are made.

EFFECT: invention provides intensification of heat transfer between the flame wall surface and a cooler.
