A system and method to transfer heat energy through a composite structure. The system includes a heat pipe extending through a thickness of the composite material. The method includes extending a heat pipe through the composite material from a first surface exposed to the heat energy to a second surface exposed to airflow.

According to one embodiment, a gear includes a steel portion that is oriented on a center axis. The steel portion includes a hub, a cylindrical rim, a web, and a plurality of engagement features. The hub is centered about the center axis. The rim has an exterior surface and an interior surface that surrounds the hub and is centered about the center axis. The web extends from an exterior surface of the hub to the interior surface of the rim. The engagement features are on the exterior surface of the cylindrical rim. The gear also includes a first composite piece adjacent to a first side of the web, the first composite piece extending from the hub to the interior surface of the rim, wherein the first composite piece does not extend past the hub towards the center axis.

A variable state planetary shifting transmission can include an input shaft, an output shaft; and a planetary system having a sun gear associated with the input shaft, a planetary carrier, and a ring gear associated with a ring housing. The transmission can include an overrunning clutch operably coupled to the planetary carrier. The transmission can include a clutch assembly coupled to the planetary carrier. The transmission is capable of changing the speed ratio between the input shaft and the output shaft by selective engagement of the clutch assembly against the ring gear which can cause either the freeing or locking of the planetary carrier by the overrunning clutch.
