METHOD OF STARTING AFTERBURNER CHAMBER OF GAS-TURBINE ENGINE Russian patent published in 1995 - IPC

FIELD: control of supply of igniting fuel to afterburner chamber. SUBSTANCE: heavy-rate mode is set by means of engine control lever, after which parameters of flight and operation of engine are measured, then fuel is fed to afterburner chamber and control of igniting fuel supply is effected; then parameters of conditions inside afterburner chamber are measured and magnitude of complex parameter of steady start is determined; relative magnitude of complex parameter (II) is compared with unity and igniting fuel is supplied by firetrace. If magnitude II is more than unity or is equal to unity, consumption of fuel fed to main combustion chamber and diameter of reactive nozzle shall be adjusted till magnitude II is less than unity or is equal to unity. EFFECT: enhanced reliability of start. 2 cl, 3 dwg
