LPS CHAMBER WITH SUPERSONIC NOZZLE FROM ALUMINUM ALLOY

摘要

FIELD: liquid propellant rocket engines.;SUBSTANCE: invention relates to liquid propellant rocket engines (LPRE). LPRE chamber with a supersonic part of an aluminum alloy nozzle, containing a cooled subsonic part made of a steel outer jacket and an inner wall made of a bronze alloy with underwater fuel component lines, and a supersonic part of an aluminum alloy nozzle, according to the invention on a cooled supersonic part of an aluminum alloy nozzle an adapter ring with a number of holes made of EP666 alloy is made, connected by soldering to the inner and outer walls of the supersonic part made of aluminum alloy, which, through a steel plate and an adapter ring, is connected to the steel jacket of the chamber with a number of holes made in it and the bronze inner wall of the subsonic part, forming a cavity connecting the cooling cavity of the subsonic part of the chamber with cooling cavity of the supersonic part of the aluminum alloy nozzle.;EFFECT: invention provides improvement of mass and energy characteristics.;1 cl, 2 dwg
