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

FIELD: engines and pumps.

SUBSTANCE: test methods of jet-turbine engines (JTE) are described in the group of inventions. When performing the test steps, alteration of the modes, which exceed as to duration the programmed flight time, is performed. Typical flight cycles are formed, based on which damageability of the most loaded parts is determined as per the programme. The required number of loading cycles during the test is determined. 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 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 5-6 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 test methods of aircraft jet-turbine engines with improved reliability of test results at any of the steps from an experimental-industrial specimen to industrial production and flight operation of aircraft engines.
