EVALUATION OF EFFECTIVENESS OF ADVANCED UNIT OF PRESSURIZATION IN LPRE COMPOSITION
Results of tests of two lamellar-ribbed improved units of pressurization in structure of oxygen-kerosene RD191 engines are presented. Estimation of effectiveness of their work in comparison with initial unit is conducted. Verification of developed methods of thermal and hydraulic calculations by comparing the calculated and experienced parameter values is performed. It is shown their suitability for practical use. Condition under which advanced unit of pressurization meets to all requirements of technical specifications is formulated. Prospectivity of its application in RD191engine instead of initial unit is substantiated.
