GAS-TURBINE ENGINE, TEST METHOD OF GAS-TURBINE ENGINE, PRODUCTION METHOD OF BATCH OF GAS-TURBINE ENGINES (VERSIONS), AND OPERATING METHOD OF GAS-TURBINE ENGINE Russian patent published in 2013 - IPC G01M15/14 

FIELD: engines and pumps.

SUBSTANCE: test methods of gas-turbine engines (GTE) are described in the group of inventions. When performing test steps, alternation of modes is performed, which exceed as to duration the programmed flight time; at that, typical flight cycles are being pre-formed, on the basis of which damageability of the most loaded parts is determined. The required number of loading cycles during the test is determined based on the above. Full scope of tests is formed, including a quick change of cycles in the complete register from quick selection of maximum or full augmented power mode till complete stop of the engine, and then, representative cycle of continuous operation with multiple alteration of modes in the whole working spectrum with various span of range of the mode change, which exceeds the flight time at least by 5 times. Quick selection of maximum or augmented power mode in some part of the test cycle is performed at the rate of acceleration and discharge.

EFFECT: development of aircraft gas-turbine engines, their test methods, adjustments, pilot and industrial production and operation with increased reliability of test results at any of the steps from pilot and industrial specimen to industrial production.
