FIELD: engines and pumps.
SUBSTANCE: invention can be used in electronic hydro mechanical ACS of multimode gas turbine engines with afterburner combustion chamber in operation at training conditions to ensure reliable fuel firing at actuation of afterburning from lower modes of cold engine (below "Maximum" mode). By signal of afterburner chamber firing device an in-engine parameter magnitude is increased to adjust fuel feed to the main combustion chamber to preset level. After firing in afterburner chamber, fuel feed rate in is decreased by the same amount.
EFFECT: higher efficiency.
