Abstract
An electrical swivel system may have a movable swivel member adapted to connect to a landing gear and a fixed swivel member adapted to connect to an airframe.

An electrical swivel system comprising:
- a movable swivel member comprising:
- a movable member mounting apparatus mounting the movable swivel member to a landing gear;
- an external gear connector through which electrical signals are conducted;
- a movable member interface apparatus;
- a fixed swivel member comprising:
- a fixed member mounting apparatus mounting the fixed swivel member to an airframe;
- an external aircraft connector through which electrical signals are conducted;
- and
- a fixed member interface apparatus;
- wherein the movable member interface apparatus comprises a movable track comprising a moveable track electrical contact,
- wherein the fixed member interface apparatus comprises a fixed track comprising a fixed track electrical contact,
- wherein the movable track electrical contact contacts the fixed track electrical contact so that electrical current is conducted,
- wherein the movable swivel member and the fixed swivel member comprise complementary shapes whereby the movable swivel member nests within the fixed swivel member,
- wherein the movable swivel member travels along an arc length between a first end of the fixed swivel member and a second end of the fixed swivel member, and
- wherein the fixed swivel member further comprises a tension member disposed between the fixed member mounting apparatus and the fixed member interface apparatus whereby force is exerted on the fixed track electrical contact.
