FUEL NOZZLE FOR GAS TURBINE ENGINES

摘要

A fuel nozzle for gas turbine engines in which the fuel jets leaving the fuel metering sections draw-in air delivered by the compressor of the gas turbine engine through passages provided in the nozzle housing; a piston-shaped insert is arranged in the nozzle housing to move relative to the latter so as to vary the quantity of compressor air to be supplied to the fuel nozzle and/or the quantity of the fuel/air mixture to be discharged from the nozzle as the piston-shaped insert means is displaced.
