FIELD: astronautics.
SUBSTANCE: invention relates to rocket engineering, namely to liquid-propellant engine (LPE) operating according to scheme with afterburning of generator gas. Liquid-propellant rocket engine comprises gas duct and support of attachment, at that, support of attachment is installed on gas duct, is cooled and contains cooling channels. Fastening support consists of at least two parts, contains coolant bypass lines between its parts, and support parts are connected by flange connection.
EFFECT: invention provides for dense arrangement of engine, as well as arrangement of fuel assembly above critical section of combustion chamber.
