Abstract:
A rotorcraft is disclosed. The rotorcraft may include an airframe, at least one engine connected to the airframe, and a rotor connected to the airframe. The rotor may include a hub, a rotor blade, and a feathering spindle connecting the rotor blade to the hub. The rotorcraft may further include a flow of oil passing proximate the feathering spindle. The flow of oil may cool the feathering spindle during take off and landing of the rotorcraft. Additionally, the flow of oil may heat the feathering spindle during travel of the rotorcraft at altitude.
