Abstract:
1. A combustion system for a gas turbine engine, comprising: a) a housing defining a pressure vessel; b) a master injector mounted to the housing for injecting fuel along a central axis defined through the pressure vessel; c) a plurality of slave injectors each disposed radially outward of and substantially parallel to the master injector for injecting fuel and air in an injection plume radially outward of fuel injected through the master injector, wherein the master injector and slave injectors are configured and adapted so the injection plume of the master injector intersects with the injection plumes of the slave injectors; and d) an outlet bulkhead mounted to outlets of each of the master and slave injectors, the outlet bulkhead having an outlet opening sealed around an outlet of each injector; wherein a floating collar is movably mounted to each outlet opening to seal between the outlet of each respective injector and the outlet bulkhead to accommodate relative thermal expansion and contraction of the injectors and outlet bulkhead.
