METHOD OF DETERMINING COEFFICIENT OF GAS FLOW THROUGH NOZZLE ASSEMBLY OF TURBINE BYPASS GAS TURBINE ENGINE Russian patent published in 2016 - IPC F02C9/00 G01M15/14 

FIELD: machine building.

SUBSTANCE: invention relates to determination of coefficient of gas flow through nozzle assembly of turbine during testing, and can be used in bypass gas turbine engines. For determining values of parameters of gas flow rate A_g coefficient tests of bypass gas turbine engine gas generator are carried out and air pressure is measured after compressor $${Р}_k^{\ast },$$ air temperature before and after compressor $${Т}_{вx}^{\ast }$$ and $${Т}_k^{\ast },$$ air flow in compressor G_b, fuel consumption G_t, air flow rate, participating in burning of G_bfuel, measured as result of test parameters values of gas flow G_g, gas pressure $${Р}_G^{\ast },$$ gas temperature before turbine $${Т}_G^{\ast }$$ and obtained values are included in formula for determining of gas flow rate A_g coefficient.

EFFECT: method provides higher reliability of gas flow through bypass gas turbine engine turbine nozzle assembly.
