FIELD: engines and pumps.
SUBSTANCE: invention relates to missilery and can be used in production of nozzles of liquid-propellant jet engines (LPJE). Inner shell lengthwise main ribs, arranged inside cooling loop and in the zone of maximum rib spacing, feature increased thickness, their length making at least double rib spacing in the said zone. Note here that two or more radial groves are made nearby the nozzle larger edge. Note also that total area of radial groove cross section makes at least not smaller than one radial groove cross section area. Mind that aforesaid grooves are spaced apart for at least dual spacing between lengthwise ribs.
EFFECT: higher strength of both nozzle shell welded pack and that of nozzle proper.
