Electrical power transfer system for propeller system

摘要

A propeller system (10) for an aircraft includes a propeller assembly rotatable about a central axis (28) and a reduction gearbox (16) operably connected to the propeller assembly via a propeller shaft (18). An electrical power transfer system is positioned such that the gearbox (16) is located axially between the electrical power transfer system and the propeller assembly. The electrical power transfer system includes a slip ring assembly (40) secured to an oil transfer tube (24) extending to the propeller assembly and a brush block (34) interactive with the slip ring assembly (40) to transfer electrical power to a plurality of lead wires (50) extending from the slip ring assembly (40) to the propeller assembly. The brush block (34) is positioned such that brush block tips (46) of the brush block (34) extend toward the slip ring assembly (40) in a substantially radial direction relative to the central axis (18) of the propeller assembly.
