Abstract
1. Смесительная головка, состоящая из расширяющейся к выходу форкамеры со струйными форсунками окислителя и горючего, каналов подвода окислителя и горючего, отличающаяся тем, что форкамера на участке подвода струйных форсунок имеет смесительную камеру с постоянной площадью поперечного сечения, равной 1,0÷1,2 суммарной площади поперечного сечения форсунок и длиной, равной длине совместного пробега струй до окончания периода жидкофазной индукции топлива. ! 2. Устройство по п.1, отличающееся тем, что струйные форсунки выполнены с пересекающимися осями под углом 45-65°. ! 3. Устройство по п.1 или 2, отличающееся тем, что смесительная камера имеет цилиндрическую форму и переходит в коническую форкамеру, расширяющуюся к выходу. 1. The mixing head, consisting of a pre-expanding chamber with jet oxidizer and fuel nozzles, oxidizer and fuel supply channels, characterized in that the prechamber at the jet nozzle supply section has a mixing chamber with a constant cross-sectional area of 1.0 ÷ 1, 2 of the total cross-sectional area of the nozzles and a length equal to the length of the combined path of the jets until the end of the period of liquid-phase induction of fuel. ! 2. The device according to claim 1, characterized in that the jet nozzles are made with intersecting axes at an angle of 45-65 °. ! 3. The device according to claim 1 or 2, characterized in that the mixing chamber has a cylindrical shape and passes into a conical prechamber expanding towards the exit.
