FIELD: mechanical engineering; gas-turbine engines. ^ SUBSTANCE: in process of operation of starting torch igniter of combustion chamber of gas-turbine engine, air is delivered into igniter combustion chamber along its walls in direction to nozzle. Simultaneously additional air jet is fed into igniter combustion chamber in direction of flame throw-over device under supercritical pressure differential, and ratio of rate of air jet to summary air rate through igniter should be equal to or less than 0.24. Invention makes it possible to create flame torch pulsating at frequency equal to ignition frequency and to eliminate separate long flame-outs. ^ EFFECT: provision of reliable starting of gas-turbine engine. ^ 1 dwg |
