FIELD: rocket manufacturing.
SUBSTANCE: sealing of the gas system in the points of installation of the functional members is preliminarily performed by simulators of the control actuator functional members. Then the preset value of air pressure in the source of pneumatic supply is set, and air is fed to the control actuator gas system through a service storage vessel, in which the air pressure is measured. The gas system passage flow sections are estimated by comparison of the value of the measured air pressure in the service storage vessel with the maximum allowable value. The device uses a service storage vessel made with inlet, outlet and measurement connections. The service storage vessel communicates with the source of pneumatic supply through the inlet connection, with the specimen under test-through the outlet connection, and with the pressure gauge - through the measurement connection. The inlet and outlet connections are installed on the front and rear walls of the service storage vessel respectively, and the measurement connection is installed on its side surface. The inlet connection is provided with a measuring orifice with a flow section area making up 0.7 to 0.9 of the allowable passages of the control actuator, and the flow section area of the outlet connection exceeds the allowable minimum sections area of the passages of the control actuator gas system at least by 5 times.
EFFECT: enhance accuracy of check and reduced labor content of the test.
