FIELD: engine building.
SUBSTANCE: gas turbine engine has configuration of annular cascade of fuel nozzles in combustion chamber. When the turbine blade rotates inside the gas turbine engine, it is subjected to lifting and resistance forces based on the illuminated nozzles configuration.
EFFECT: configuration of the illuminated nozzles, which leads to minimum non-stationary forces, which is experienced by the turbine blade, is determined to increase service life of the turbine blade and to limit any structural failures.
