Claims
- 1. A fuel injection system for use in the combustor section of a gas turbine engine said fuel injection system comprising:
- a plurality of generally downstream facing fuel nozzles wherein a portion of said fuel nozzles are connected to a shutoff valve means which is interruptible, a means for interrupting said valve means in response to a control signal, and
- a means for generating said control signal based on the gas turbine engine fuel to air ratio and an overriding weight on wheels signal.
- 2. A fuel injection system for use in the combustor section of a gas turbine engine said fuel injection system comprising:
- first and second fuel lines,
- first and second pluralities of generally downstream facing fuel nozzles in fluid supply communication with said first and second fuel lines respectively,
- a shutoff valve interposed in said first fuel line, a means for shutting on and off said valve in response to a control signal; and
- a means for generating said control signal based upon the gas turbine engine fuel to air ratio and an overriding weight on wheels signal.
- 3. A fuel injection system as set forth in claim 2 comprising: first and second fuel manifolds disposed between said first and second fuel lines and said first and second pluralities of fuel nozzles respectively.
- 4. A fuel injection system as set forth in claim 3 wherein: said first and second pluralities of fuel nozzles are arranged in a generally circular and alternating pattern.
- 5. A fuel injection system as set forth in claim 4 including:
- a fuel control in supply communication with said first and second fuel lines.
- 6. A fuel injection system as set forth in claim 5 wherein said means for generating said control signal is an electronic engine control which controls said shutoff valve and said fuel control.
- 7. A fuel injection system as set forth in claim 6 wherein:
- said electronic engine control is a digital electronic engine control.
