| MATHEMATICAL MODEL OF DYNAMIC PROCESSES OF PRESSURE STABILIZER OF POWERFUL ROCKET ENGINES
The mathematical model of dynamic processes of pressure stabilizer, made on single-stage scheme with spool-and-sleeve. The model is designed to conduct alternative calculations for optimization of main design parameters of stabilizer taking into account dynamics of upstream and downstream lines.
Keywords: LPRE, mathematical model, pressure stabilizer, optimization.

APPLICATION OF CALCULATION - EXPERIMENTAL MODEL FOR FORECAST OF PARAMETERS OF OPERATIONAL PROCESSES OF LRE IN CYCLE OF REPEATED FIRE TESTS
The algorithm of formation of calculation-experimental model (CEM) of LPRE is presented. Such algorithm provides forecast of parameters of operational processes of LRE at repeated fire test. The efficiency of use of CEM at multiple fire tests in a wide range of control by thrust and mixture ratio, and at change of fuel brands.
Keywords: LPRE, calculation-experimental model, slowly changing parameters, flow characteristics, correction of model, fire test.
