FIELD: experimental determination of interballistic and power characteristics of charges for multi-regime rocket engines.
SUBSTANCE: a sleeve with a spring valve in the bottom part is joined in the bench test set to the combustion chamber, an adjusting piston is positioned in the valve neck, exit ports are made on the side surface of the neck, the necks are closed with an outer shutter kinematically linked with a drive, control panel and a pressure transducer in the combustion chamber, and a nozzle unit with an insert of a definite critical section is joined to the sleeve.
EFFECT: enhanced accuracy of determination of the charge burning rate for each regime of the engine and specific impulse of the solid propellant using a real charge in the tests.
