Abstract

A propeller assembly (10) is provided with a brush wear indicating arrangement, on a brush assembly (36) engaging with a plurality of slip rings (34) for transferring electrical energy to blade (12) heating element (32). The brush wear indicating arrangement includes an insert (64), a first electrically conductive brush (120), and a wear indicator (122). The insert is disposed within a brush block housing (60) and defines a first aperture (100). The first electrically conductive brush (120) is movably engaged within the first aperture (100). The electrically conductive brush (120) is configured to move outward from the first aperture (100) as a wear surface of the first electrically conductive brush (120) wears. The wear indicator (122) is coupled to the first electrically conductive brush (120). The wear indicator (122) is configured to extend beyond a first insert face (90) of the insert as wear condition of the wear surface of the first electrically conductive brush (120) exceeds a wear threshold.
