SLIPRING BUSHING ASSEMBLY FOR MOVEABLE TURBINE VANE

摘要

A bushing assembly for a turbine vane includes a bushing (60) and a housing (62). The bushing (60) includes a bore for receiving a trunnion (54) of the vane, a first electrical contact (66) carried on an outer surface thereof, and a first conductor extending from the first electrical contact (66). The first electrical contact (66) is adapted to be connected to a heating element (72) disposed on the vane. The housing (62) is positioned over the bushing (60) and rotatable relative to the bushing (60). The housing (62) includes a second electrical contact (86) disposed in contact with the first electrical contact (66) and a second conductor extending from the second electrical contact (86) for connection to an electrical power source.
