MIXER ELEMENT FOR NOZZLE HEAD OF LIQUID-PROPELLANT ENGINE

摘要

FIELD: engines and pumps. ^ SUBSTANCE: mixer element for a nozzle head of a chamber of liquid-propellant engines (LPE) comprises several coaxially installed bushings that create circular cavities to supply fuel and oxidant. Circular cavities of components supply at the side of the combustion chamber cavity are closed with spacers, where holes are made to supply fuel components to the combustion area. At the side opposite to the combustion zone the specified cavities are closed with a shaped bottom, the inner surface of which is made as stepped. In the bottom there are radial and axial channels that connect cavities of fuel components supply with any circular cavities. ^ EFFECT: invention provides for maximum possible completeness of combustion of various types of fuels at low quantity of mixer elements on a nozzle head. ^ 2 dwg
