Protective cap for a rotor blade

1. A protective cap for a trailing edge of a rotor blade of a wind turbine for use during transportation, handling, or maintenance of the rotor blade, said protective cap comprising:

a body having a first leg and a second leg connected by a cap member, wherein said cap member is integral with said first and second legs, said cap member configured to cover at least a portion of the trailing edge of the rotor blade when said protective cap is installed on the rotor blade,

wherein said first leg is configured to resiliently engage a suction side of the rotor blade and said second leg is configured to resiliently engage a pressure side of the rotor blade such that the protective cap effectively holds itself on the rotor blade when installed.

2. The protective cap of claim 1 , wherein said cap member is configured to provide a gap between an inner surface of said protective cap and the trailing edge of the rotor blade when said protective cap is installed on the rotor blade.

3. The protective cap of claim 1 , wherein said first and second legs each comprise a surface area, wherein said surface areas cover a portion of a pressure side and a suction side of the rotor blade.

4. The protective cap of claim 1 , wherein the first and second legs each comprise at least one flange extending substantially perpendicular therefrom.

5. The protective cap of claim 1 , wherein said first leg is configured to correspond to a profile of said suction side of the rotor blade, and wherein said second leg is configured to correspond to a profile of a pressure side of the rotor blade.

6. The protective cap of claim 2 , further comprising at least one cushion pad between said first leg and said suction side and at least one cushion pad between said second leg and said pressure side.

7. The protective cap of claim 1 , further comprising at least one cushion pad between said cap member and said trailing edge of the rotor blade.

8. The protective cap of claim 3 , wherein said protective cap extends substantially the span-wise length of the trailing edge.

9. The protective cap of claim 3 , wherein said protective cap extends a portion of the span-wise length of the trailing edge.

10. The protective cap of claim 1 , wherein the cap member comprises a substantially arcuate shape.

11. The protective cap of claim 1 , wherein the protective cap further comprises a fastening component configured to secure the protective cap to the rotor blade.

12. The protective cap of claim 11 , wherein the cap member further comprises at least one slot configured to receive the fastening component, wherein said fastening component comprises one of a strap, a sling, or a chain.

13. A protective cap for a trailing edge of a rotor blade of a wind turbine for use during transportation, handling, or maintenance of the rotor blade, said protective cap comprising:

a body having a first leg and a second leg connected by a cap member, the cap member being intergral with said first and second legs, said cap member configured to cover at least a portion of the trailing edge of the rotor blade when said protective cap is installed on the rotor blade,

wherein said cap member is configured to provide a gap between an inner surface of said protective cap and the trailing edge when said protective cap is installed on the rotor blade, and

wherein said first and second legs resiliently engage the rotor blade.

14. The protective cap of claim 13 , wherein said first leg is configured to resiliently engage a suction side of the rotor blade, and wherein said second leg is configured to resiliently engage a pressure side of the rotor blade.

15. The protective cap of claim 13 , wherein said first and second legs each comprise a surface area, and wherein each surface area comprises at least one flange extending substantially perpendicular therefrom.

16. A method for preparing a rotor blade for transportation, handling, or maintenance, the method comprising:

installing at least one protective cap on a trailing edge of the rotor blade, the protective cap comprising a body having a first leg and a second leg connected by a cap member, said cap member being integral with said first and second legs, and wherein said first and second legs resiliently engage the rotor blade; and,

securing the protective cap to the rotor blade, wherein said cap member provides a gap between an inner surface of said protective cap and the trailing edge of the rotor blade when said protective cap is secured to the rotor blade.

17. The method of claim 16 , further comprising installing at least one cushion pad between said first and second legs of the protective cap and said rotor blade.

18. The method of claim 16 , wherein securing the protective cap to the rotor blade further comprises securing at least one fastening component to the protective cap and the rotor blade, wherein the fastening component comprises one of a strap, a sling, or a chain.

19. The method of claim 18 , further comprising installing the at least one fastening component within at least one slot of the protective cap.

20. The method of claim 16 , further comprising installing the rotor blade comprising the installed protective cap within a shipping fixture, the shipping fixture being designed to have maximum dimensions equal to or less than maximum dimensions permitted for rail or truck transport.
