Abstract

A single, unitary fuel/oil manifold for a gas turbine engine is provided which comprises one or more interfaces for mounting various fuel system and lubricating system components directly to the fuel/oil manifold. The fuel/oil manifold also defines fluid passages for transferring fuel or lubricant from one component to another component. Packing numerous fuel system and lubricating system components within the fuel/oil manifold reduces cost and weight and simplifies maintenance.

First claim

What is claimed is:

1. A fuel system for a gas turbine engine, comprising:
a single piece, unitary fuel and oil manifold; and
a plurality of fuel nozzles;
the single piece, unitary fuel and oil manifold comprising:
a fuel oil cooler interface for mounting a fuel oil cooler directly to the single piece, unitary fuel and oil manifold; and
a fuel oil cooler bypass valve interface for mounting a fuel oil cooler bypass valve directly to the single piece, unitary fuel and oil manifold;
fluid passages defined in the single piece, unitary fuel and oil manifold for transferring fuel and oil from one component to another component and wherein the single piece, unitary fuel and oil manifold defines a primary passage directing a flow of the fuel to the plurality of fuel nozzles; and
a main fuel pump system interface for mounting a main fuel pump system directly to the single piece, unitary fuel and oil manifold.

2. The fuel system of claim 1 further comprising: a mass flow meter interface for mounting a mass flow meter directly to the single piece, unitary fuel and oil manifold.

3. The fuel system of claim 1 further comprising: a fuel valve interface for mounting a fuel valve directly to the single piece, unitary fuel and oil manifold.

4. The fuel system of claim 3 further comprising: an integral fuel filter housing for mounting a fuel filter directly to the single piece, unitary fuel and oil manifold.

5. The fuel system of claim 4 further comprising:
a lube plumbing interface for accommodating a lube plumbing line.

6. The fuel system of claim 5 further comprising:
a fuel plumbing interface for accommodating a fuel plumbing line.

7. The fuel system of claim 2 wherein: the fluid passages of the single piece, unitary fuel and oil manifold define a first fuel passage for accommodating a first fuel flow from the main fuel pump system to the mass flow meter.

8. The fuel system of claim 7 wherein: the fluid passages of the single piece, unitary fuel and oil manifold define a first oil passage for accommodating oil flow to the fuel oil cooler and a second fuel passage for accommodating a second fuel flow from the fuel oil cooler.

9. The fuel system of claim 8 wherein: the fluid passages of the single piece, unitary fuel and oil manifold further define the second fuel passage for accommodating the second fuel flow from the fuel oil cooler to a fuel filter.

10. The fuel system of claim 9 wherein: the fluid passages of the single piece, unitary fuel and oil manifold define a third fuel passage for accommodating a third fuel flow from the main fuel pump system to a fuel based hydraulic actuation system.

11. The fuel system of claim 10 wherein: the fluid passages of the single piece, unitary fuel and oil manifold define a fourth fuel passage for accommodating a fourth fuel flow from the fuel filter to the main fuel pump system.

12. The fuel system of claim 10 wherein: the fuel based hydraulic actuation system comprises a bleed valve actuator, a high pressure compressor vanes actuator and a low pressure compressor vanes actuator.

13. The fuel system of claim 1 wherein: the single piece, unitary fuel and oil manifold is made of cast aluminum.
