Abstract
The invention relates to a nozzle structure for rocket nozzles having a cooled nozzle wall comprising a large member of closely spaced cooling channels (2) extending from the inlet end of the nozzle to its outlet end. To facilitate the production of the cooled nozzle wall, it is suggested according to the invention that said nozzle wall consists of several elongated panels (11) which extend from the inlet to the outlet end of the nozzle and are joined together at their longitudinal side edges (7) and in each of which is formed a number of said cooling channels (2) which extend in the longitudinal direction of the panels (11).
