Abstract
1. Смесительная головка жидкостного ракетного двигателя малой тяги, состоящая из каналов подвода окислителя и горючего, смесительной камеры со струйными форсунками окислителя и горючего, площадь поперечного сечения которой больше суммарной площади форсунок окислителя и горючего, а длина равна длине совместного пробега струй до окончания периода жидкофазной индукции, отличающаяся тем, что форсунка одного из компонентов топлива соосна смесительной головке, а форсунки второго компонента выполнены в боковой стенке смесительной головки и размещены осесимметрично относительно оси центральной форсунки.2. Смесительная головка по п. 1, отличающаяся тем, что форсунки второго компонента размещены в радиальном направлении.3. Смесительная головка по п. 1, отличающаяся тем, что площадь поперечного сечения смесительной камеры равна 1,0-1,2 суммарной площади форсунок окислителя и горючего.1. The mixing head of a liquid propulsion thruster, consisting of channels for supplying oxidizer and fuel, a mixing chamber with jet nozzles of oxidizer and fuel, the cross-sectional area of which is greater than the total area of the nozzles of the oxidizer and fuel, and the length is equal to the length of the combined path of the jets until the end of the liquid phase induction, characterized in that the nozzle of one of the components of the fuel is aligned with the mixing head, and the nozzles of the second component are made in the side wall of the mixing head and placed axisymmetrically about the axis of the central nozzle. 2. A mixing head according to claim 1, characterized in that the nozzles of the second component are placed in the radial direction. The mixing head according to claim 1, characterized in that the cross-sectional area of the mixing chamber is 1.0-1.2 of the total area of the oxidizer and fuel nozzles.
