FIELD: mechanical engineering; gas-turbine engines.
SUBSTANCE: invention relates to automatic control of fuel delivery at starting of gas-turbine engines. In proposed method of metering out of fuel at starting of gas-turbine engine including measuring speed nhp of gas-turbine rotor, determining value of acceleration 
metering out fuel to maintain value 
corresponding to preset dependence 
according to invention, air temperature Tin at engine input and temperature Tpr of fuel combustion products are measured additionally, and threshold value 
is formed to dependence 
Tpr is compared with and at 
metering out of fuel is changed to reduce value 
to 
where 
is correction coefficient determined by dependence
and at 
value 
is restored according to preset dependence 
.
EFFECT: improved reliability of starting of gas turbine engine by reduction of temperature of gas-turbine engine fuel combustion products owing to optimization of fuel delivery into combustion chamber.
