Abstract:

A system for isolating electrical current in an aircraft structure includes a first structure a bearing having an outer race and an inner race and a liner disposed therebetween, the outer race having a second structure coupled thereto. A dielectric seal is secured to the outer race and engages the inner race. A conditionally non-conductive gas occupies a sealed chamber that defines a gap between the inner race and the outer race. The gap has a predetermined magnitude sufficient to prevent electrical arcing or current leakage between the inner race and the outer race at a first voltage less than that voltage resulting from a lightning strike; and/or to conduct an electrical current between the inner race and the outer race at a second voltage greater than or equal to the voltage resulting from the lightning strike.
