Abstract

An apparatus for transporting a turbine engine with a transportation fixture including a turbine engine jig having mounts for securing the turbine engine, a rotor with a drive shaft rotationally supported by a bearing, the method includes supplying a lubricant to the bearing and rotating the drive shaft while the turbine engine is in transport.

First claim

What is claimed is:

1. A turbine engine transportation fixture comprising:
a turbine engine jig having mounts for securing a turbine engine;
a rotary driver configured to couple to an input on the turbine engine for continuously rotating a rotor of the turbine engine independently of engine combustion; and
a lubricant reservoir configured to couple with a bearing coolant circuit for the turbine engine.

2. The turbine engine transportation fixture of claim 1 , wherein at least one of the mounts is a wing mount.

3. The turbine engine transportation fixture of claim 1 , wherein the rotary driver is a friction driver configured to couple to a fan aft shaft of the turbine engine.

4. The turbine engine transportation fixture of claim 1 , wherein the rotary driver is a motor.

5. The turbine engine transportation fixture of claim 4 , wherein the motor is configured to directly or indirectly couple to a fan aft shaft of the turbine engine.

6. The turbine engine transportation fixture of claim 4 , wherein the motor is configured to directly or indirectly couple to an accessory gearbox of the turbine engine.

7. The turbine engine transportation fixture of claim 4 , wherein the motor is an electric motor.

8. The turbine engine transportation fixture of claim 7 , wherein the electric motor is configured to receive power from a transport vehicle.

9. The turbine engine transportation fixture of claim 7 , wherein the electric motor is configured to receive power from a battery.

10. The turbine engine transportation fixture of claim 1 , wherein the lubricant reservoir comprises a recirculation pump.

11. The turbine engine transportation fixture of claim 1 , wherein the turbine engine comprises at least one drive shaft rotationally supported by at least one bearing and the at least one drive shaft is coupled to the input such that the at least one drive shaft rides on a film of lubricant between the at least one drive shaft and the bearing without the at least one drive shaft physically contacting the bearing.

12. The turbine engine transportation fixture of claim 11 , wherein the input is an accessory gearbox rotatably coupled to the at least one drive shaft.

13. The turbine engine transportation fixture of claim 11 , wherein the input is a fan aft shaft coupled to the at least one drive shaft.

14. The turbine engine transportation fixture of claim 13 , wherein the fan aft shaft is mechanically coupled to the at least one drive shaft.

15. The turbine engine transportation fixture of claim 13 , wherein the fan aft shaft is frictionally coupled to the at least one drive shaft.

16. The turbine engine transportation fixture of claim 11 , wherein the bearing coolant circuit further comprises a supply circuit and a return circuit.

17. The turbine engine transportation fixture of claim 16 , further comprising a recirculation pump fluidly coupled to the bearing coolant circuit to supply lubricant from the reservoir to the at least one bearing via the supply circuit and to return the supplied lubricant to the reservoir via the return circuit.

18. The turbine engine transportation fixture of claim 11 , wherein the at least one drive shaft is a high pressure drive shaft and a low pressure drive shaft.

19. The turbine engine transportation fixture of claim 18 , wherein the low pressure drive shaft and the high pressure drive shaft each are rotationally supported by axially-spaced bearings.

20. The turbine engine transportation fixture of claim 11 , wherein the rotary driver is configured to rotate the at least one drive shaft at a predetermined speed.
