TESTING BENCH FOR GAS GENERATORS OF TURBOJET BYPASS ENGINES Russian patent published in 2017 - IPC G01M15/14 

FIELD: engines and pumps.

SUBSTANCE: testing bench for gas generators of turbojet bypass engines has an air duct with flaps installed on the path and a turbojet bypass engine. The duct inlet is connected to the external circuit of the turbojet engine, and the output is coupled with the tested gas generator.

EFFECT: airflow of the external circuit of the turbojet engine without mixing the flows of the external and internal circuits together with the use of dampers that let air into the inlet of the tested gas generator and into the exhaust air duct simultaneously simulate the gas dynamic parameters of the air at the inlet to the tested gas generator; simplified test procedures.
