Abstract

A gas turbine engine comprises a compressor, a combustor and a turbine. A housing for the gas turbine engine includes a mount member to define a vertically upper location. Sides of the engine are defined on opposed sides of the mount, with a fuel filter, a fuel pump and a fuel flow meter being positioned on a first side and an oil pump, an oil filter and an oil tank positioned on a second of the sides.

Claims

1. A gas turbine engine comprising:

a compressor, a combustor and a turbine; and

a housing for said gas turbine engine, with said housing including a mount member to define a vertically upper location, and sides of the engine being defined on opposed sides of the mount, with a fuel filter, a fuel pump and a fuel flow meter being positioned on a first side and an oil pump, an oil filter and an oil tank positioned on a second of said sides.

2. The gas turbine engine as set forth in claim 1, wherein pivoting doors are associated with each of said first and second sides to provide access to components.

3. The gas turbine engine as set forth in claim 2, wherein an electronic engine control, a prognostic health and monitoring unit and an igniter box are all positioned on one of said first and second sides.

4. The gas turbine engine as set forth in claim 3, wherein a fuel/oil cooler is positioned on a top side of said engine.

5. The gas turbine engine as set forth in claim 3, wherein said fuel pump is positioned vertically below the fuel flow meter.

6. The gas turbine engine as set forth in claim 5, wherein said oil pump is positioned vertically below said oil tank.

7. The gas turbine engine as set forth in claim 6, wherein a main gearbox is positioned in a vertically lower quadrant on said engine.

8. The gas turbine engine as set forth in claim 7, wherein a generator is also positioned in said vertically lower quadrant of said gas turbine engine.

9. The gas turbine engine as set forth in claim 1, wherein an electronic engine control, a prognostic health and monitoring unit and an igniter box are all positioned on one of said first and second sides.

10. The gas turbine engine as set forth in claim 9, wherein a fuel/oil cooler is positioned on a top side of said engine.

11. The gas turbine engine as set forth in claim 9, wherein said fuel pump is positioned vertically below the fuel flow meter.

12. The gas turbine engine as set forth in claim 11, wherein said oil pump is positioned vertically below said oil tank.

13. The gas turbine engine as set forth in claim 11, wherein a main gearbox is positioned in a vertically lower quadrant on said engine.

14. The gas turbine engine as set forth in claim 13, wherein a generator is also positioned in said vertically lower quadrant of said gas turbine engine.

15. The gas turbine engine as set forth in claim 1, wherein a fuel/oil cooler is positioned on a top side of said engine.

16. The gas turbine engine as set forth in claim 1, wherein said fuel pump is positioned vertically below the fuel flow meter.

17. The gas turbine engine as set forth in claim 1, wherein said oil pump is positioned vertically below said oil tank.

18. The gas turbine engine as set forth in claim 16, wherein a main gearbox is positioned in a vertically lower quadrant on said engine.

19. The gas turbine engine as set forth in claim 18, wherein a generator is also positioned in said vertically lower quadrant of said gas turbine engine.

20. The gas turbine engine as set forth in claim 1, wherein a generator is positioned in a vertically lower quadrant of said gas turbine engine.
