ROCKET ENGINE Russian patent published in 1995 - IPC

FIELD: rocket engineering. SUBSTANCE: front frame is mounted on the inner cylindrical side of the housing. The rear frame is mounted on outer side of the inlet part of the nozzle set. The front frame is constructed as a metal gear cylindrical ring with thick- walled skirt. Through longitudinal grooves, which separate the skirt into segments, are made over periphery at the bottom of the skirt. The rear frame is made up as a split metal thin-walled cylindrical-and-conical ring. The conical part is made up as T-shaped tabs. Rectangular stops 13 with radiused flange perpendicular to generatrix of the engine are interposed between the tabs. The T-shaped tabs and stops are conjugated via a radius. The cylindrical part of the ring of the rear frame is conjugated with the outer side of the nozzle set and interposed between the spiral ring layers of forced shell of the housing, insert 14 made of a composition material being received in the ring chute. The outer contour of flanges is a circumference. A lock constructed as thin-walled of Z-like cross section. The front frame is armored over the skirt with a resilient thin-walled collar. EFFECT: enhanced efficiency. 3 cl, 5 dwg
