GAS-TURBINE ENGINE TESTING METHOD Russian patent published in 2018 - IPC G01M15/14 

FIELD: engines and pumps.

SUBSTANCE: invention relates to the field of aircraft engine construction, namely to methods for testing aviation gas turbine engines (GTE). For a type of engine including an anti-icing system, preliminary tests are carried out in the selected operating mode, the parameters are measured when the anti-icing system is switched off and when the anti-icing system is switched on in the operating range of the rotor speed, calculating the correction factors to the measured parameters by the ratio of the values of the parameters measured with the de-icing system on, to the values of the parameters measured with the de-icing system switched off, the dependence of the correction factors on the measured parameters on the rotational speed of the rotors Ki=f(n), and when testing other engines in icing conditions with the de-icing system on, the measured values of the parameters are multiplied by the coefficients obtained.

EFFECT: method makes it possible to obtain reliable results when testing GTE under icing conditions with the anti-icing system on.
