Abstract
A gas turbine engine combustor has inboard and outboard walls. A forward bulkhead extends between the walls and cooperates therewith to define a combustor interior volume. Bluff body fuel injectors are along the bulkhead.
Claims20
A gas turbine engine combustor comprising:
- an inboard wall;
- an outboard wall;
- a forward bulkhead extending between the inboard and outboard walls and cooperating therewith to define a combustor interior volume;
- and
- at least one fuel injector along the forward bulkhead and comprising:
- means for introducing fuel to a flow of air entering the interior volume for combusting the fuel and air;
- and
- means for inducing turbulence and promoting local flame stabilization of the combusting air and fuel.

A gas turbine engine combustor comprising:
- an inboard wall;
- an outboard wall;
- a forward bulkhead extending the inboard and outboard walls and cooperating therewith to define a combustor interior volume;
- and
- a fuel injector system comprising:
- an elongate body having first and second sides and a bluff end extending between the first and second sides;
- a first air flowpath along the first side of the body;
- a second air flowpath along the second side of the body;
- a plurality of first fuel nozzles positioned to direct fuel to a first flow of air in the first air flowpath;

- a plurality of second fuel nozzles positioned to direct fuel to a second flow of air in the second air flowpath.
8 more elements
A method for engineering a gas turbine engine combustor having an inboard wall, an outboard wall, and a forward bulkhead extending the inboard and outboard walls and cooperating therewith to define a combustor interior volume, the method comprising:
- configuring the combustor to have air inlet passageway portions in the forward bulkhead, with non-passageway portions therebetween;
- selecting width of the inlet passageway portions so as to provide a desired airflow;
- and
- selecting width of the non-passageway portions so as to provide a desired flame stability.
