Abstract: 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.

Abstract: An interconnect drive system for an aircraft has a driveline and clutch control system. The driveline comprises a shaft for each propulsion assembly, each shaft for transferring torque to and from the associated propulsion assembly, and a clutch operably coupling the shafts and configured for selective engagement. The clutch is capable of transferring a first amount of torque between the shafts while engaged and a second amount of torque between the shafts while disengaged. The system also has a clutch control system, comprising a computer operably connected to the clutch for controlling operation of the clutch and sensors for sensing torque applied to the driveline, output from the sensors being communicated to the computer. The computer commands operation of the clutch in response to the output from the sensors, the clutch being commanded to disengage to relieve a transient torque imbalance in the driveline.

Abstract: An aircraft rotor mast assembly that includes a composite rotor mast and a rotor housing surrounding the rotor mast. The rotor mast includes a first end, a second end, and a length therebetween. The rotor mast includes a plurality of circular openings proximate the first end to accommodate bolts for the fixation of a rotor hub to the rotor mast. The second end of the rotor mast includes a flange, wherein the flange defines a plurality of openings therethrough to accommodate the attachment of the rotor mast to a transmission.
