FIELD: engines and pumps. ^ SUBSTANCE: invention is related to liquid-propellant rocket engines. Mixing head of liquid propellant rocket engine chamber comprises oxidant unit, fuel unit with fire bottom, nozzles installed in units and cavities that connect them to combustion chamber cavity, anti-pulsation partitions installed on fire bottom and separating fire bottom into isolated sectors, at that cooling channels are provided inside anti-pulsation partitions, and channels are connected to fuel unit cavity, at that fuel supply to cavity of cooling channels is realised via peripheral parts of partitions, and discharge is done via central parts. Anti-pulsation partitions are arranged in the form of fastened rectangular section tubes, cavities of which are connected to each other. ^ EFFECT: elimination of high frequency oscillations and reduction of fuel components consumption resultant from transportation losses and reduction of speed. ^ 2 cl, 4 dwg |
