FIELD: engines and pumps.
SUBSTANCE: invention relates to ground control of normal operation of gas turbine engine mounted at aircraft. For this, appropriate tests are conducted at running gas turbine engine. Starting from definite rpm, fuel flow rate is quickly reduced in programmed manner to evaluate engine combustion chamber resistance to self-quenching at in-flight fast rpm drop.
EFFECT: higher reliability of diagnostics.
