This invention relates to improvements in electric power systems for aircraft and, more particularly, to such systems which provide both starter and generator functions. The present invention has particular applicability to starter generators for helicopters having a body with an end bell, a commutator head assembly and a fan cover assembly, and wherein the starter generator does not have an end bell that permits air to exhaust through said end bell. The starter generator of the present invention has a commutator head assembly having a frame with a top end and a base end, the top end being adapted to fit within the fan cover assembly and be retained therein by a suitable means, the commutator head assembly having with a plurality of slots that are designed to exhaust air flow passing over one or more brushes in the starter generator.
