Abstract

A gas turbine engine component assembly according to an exemplary aspect of the present disclosure includes, among other things, a nacelle including a moveable portion. A generator is configured to be received within a space established by the nacelle. A plurality of cables are at least partially supported on the moveable portion of the nacelle, the plurality of cables being selectively electrically coupled with the generator.

First claim

We claim:

1. A gas turbine engine component assembly, comprising:
a nacelle including a moveable portion;
a generator configured to be received within a space established by the nacelle;
a plurality of cables at least partially supported on the moveable portion of the nacelle, the plurality of cables being selectively electrically coupled with the generator; and
a connector including a first portion supported within the space near the generator and a second portion coupled to the plurality of cables near an end of the cables, the first and second portions being selectively coupled to electrically couple the cables with the generator, wherein
the moveable portion of the nacelle is moveable between an open position and a closed position;
the connector second portion is supported on the moveable portion of the nacelle; and
the connector first portion is situated in a position where the connector second portion makes an electrically conductive connection with the connector first portion when the moveable portion of the nacelle is in the closed position.

2. The assembly of claim 1 , wherein
at least one of the connector first portion or the connector second portion comprises a male connector member; and
the other of the connector second portion or the connector first portion comprises a corresponding female connector member situated to at least partially receive the male connector member when the moveable portion of the nacelle is in the closed position.

3. The assembly of claim 1 , wherein
the connector first portion is magnetically coupled with the connector second portion when the moveable portion of the nacelle is in the closed position.

4. The assembly of claim 1 , wherein the connector first and second portions are electrically disconnected when the moveable portion of the nacelle is in the open position.

5. The assembly of claim 1 , wherein the connector first portion is formed as part of the generator.

6. A gas turbine engine component assembly, comprising:
a nacelle including a moveable portion;
a generator configured to be received within a space established by the nacelle; and
a plurality of cables at least partially supported on the moveable portion of the nacelle, the plurality of cables being selectively electrically coupled with the generator;
the moveable portion of the nacelle has an inner surface facing toward the generator; and
the cables are at least partially supported on the inner surface; and
a plurality of brackets secured to the inner surface of the moveable portion of the nacelle, each of the brackets supporting a corresponding section of at least one of the cables.

7. A gas turbine engine component assembly, comprising:
a nacelle including a moveable portion that at least partially establishes a cavity within the nacelle when the moveable portion is in a closed position; and
an electrically conductive connector including a first connector portion within the cavity and a second connector portion supported on the moveable portion, the first and second connector portions selectively establishing an electrically conductive connection when the moveable portion moves into the closed position.

8. The assembly of claim 7 , comprising
a plurality of cables at least partially supported on the moveable portion of the nacelle, the plurality of cables being electrically coupled with the second connector portion.

9. The assembly of claim 8 , comprising:
a generator near the first connector portion within the cavity and electrically connected with the connector first portion, and wherein the cables are electrically connected to the generator when the moveable portion of the nacelle moves into the closed position.

10. The assembly of claim 9 , wherein the connector first portion comprises a part of the generator.

11. The assembly of claim 8 , wherein
the moveable portion of the nacelle has an inner surface; and
the cables are at least partially supported on the inner surface.

12. The assembly of claim 11 , comprising
a plurality of brackets secured to the inner surface of the moveable portion of the nacelle, each of the brackets supporting a corresponding section of at least one of the cables.

13. The assembly of claim 7 , wherein
at least one of the connector first portion or the connector second portion comprises a male connector member; and
the other of the connector second portion or the connector first portion comprises a corresponding female connector member situated to at least partially receive the male connector member when the moveable portion of the nacelle is in the closed position.

14. The assembly of claim 13 , wherein
the male connector member comprises a tab; and
the female connector member comprises a clamp spring.

15. The assembly of claim 7 , wherein the connector first portion is magnetically coupled with the second portion.

16. The assembly of claim 7 , wherein the connector first and second portions are electrically disconnected when the moveable portion of the nacelle is in another position.

17. A method of working on a gas turbine engine, comprising:
moving a nacelle portion into one of an open position or a closed position; and at least one of:
establishing an electrically conductive connection between an integrated drive generator and a plurality of cables at least partially supported on the nacelle portion when moving the nacelle portion into the closed position; or
disconnecting the electrically conductive connection between the integrated drive generator and the plurality of cables when moving the nacelle portion into the open position.
