Fuel injector mounting system

Abstract

A system is provided for mounting fuel injectors to a gas turbine engine, including an engine casing having an aperture formed therein and a plurality of fuel injectors, each fuel injector having a respective flange for mounting the fuel injectors to the casing at the aperture so that the fuel injectors extend side-by-side into the engine. The flanges are dismountably sealed to an inner side of the casing. The aperture and the flanges are configured so that, when dismounted, each fuel injector is configured to rotate into an orientation relative to the aperture which allows each of the respective flanges to pass though the aperture and the fuel injector to be withdrawn from the casing. The flanges have respective sealing formations which engage with their neighboring flanges when the fuel injectors are mounted to the casing to close off the aperture and to form seals between the flanges.
