METHOD TO CONTROL METERING OUT OF FUEL AT STARTING OF GAS-TURBINE ENGINE

摘要

FIELD: mechanical engineering; gas-turbine engines. ^ SUBSTANCE: invention relates to automatic control of delivery of fuel at starting of gas-turbine engines. In proposed method of control of fuel metering out at starting of gas-turbine engine including measuring of speed nhp of gas-generator rotor, determining value of acceleration control of gas generator rotor speed nhp to preset dependence and limiting metering out of fuel to program dependence according to invention, threshold and program values of acceleration and are formed additionally, actual value is compared with and at enabling signal is formed to correct program dependence at preset speed of change of correction coefficient actual value is compared with program value and at enabling signal is cancelled and limiting of fuel metering out is continued according to corrected program dependence and repeated starting of gas turbine engine are effected taking into account changed value of coefficient K. ^ EFFECT: improved reliability of engine at starting conditions by automatically correcting program dependence of limiting of fuel metering out. ^ 1 dwg
