Abstract
Systems and methods for preventing fuel leakage in a gas turbine engine are provided. A fuel accumulation system includes a control valve section fluidly coupled to a fuel manifold passage and an accumulator valve section fluidly coupled at a first side to the control valve section. The control valve section is configured to control expansion of a fluid flowing in the fuel manifold passage. The accumulator valve section is configured to receive fluid expanded in the fuel manifold passage via the control valve section.
Claims20
A fuel accumulation system for a gas turbine engine comprising:
- a control valve section fluidly coupled to a fuel manifold passage and configured to control expansion of a fluid flowing in the fuel manifold passage;
- and
- an accumulator valve section fluidly coupled at a first side to said control valve section and configured to receive fluid expanded in the fuel manifold passage via said control valve section.
A method of preventing fuel leakage in a gas turbine engine, said method comprising:
- controlling expansion of a fluid flowing in a fuel manifold passage using a control valve section fluidly coupled to the fuel manifold passage;
- and
- receiving fluid expanded in the fuel manifold passage via the control valve section at an accumulator valve section fluidly coupled to the control valve section.
A gas turbine engine comprising:
- a fuel split valve;
- and
- a fuel accumulation system coupled to said fuel split valve, said fuel accumulation system comprising:
- a control valve section fluidly coupled to a fuel manifold passage and configured to control expansion of a fluid flowing in the fuel manifold passage;
- and
- an accumulator valve section fluidly coupled at a first side to said control valve section and configured to receive fluid expanded in the fuel manifold passage via said control valve section.
