Abstract
A rotorcraft is disclosed. The rotorcraft may include an airframe comprising a mast defining an interior cavity, at least one compressor connected to the airframe, and a rotor. The rotor may include a hub and a rotor blade. The hub may connect to the mast to rotate with respect thereto. The hub may also define an interior cavity. The rotor blade may form a radial conduit extending radially therewithin. A flow of compressed air generated by the at least one compressor may pass from the at least one compressor, through the interior cavity defined by the mast, through the interior cavity defined by the hub, and into the radial conduit. A swashplate assembly controlling pitch of the rotor blade may be located exterior to the hub and mast. Accordingly, the swashplate assembly may not be heated by the flow of compressed air.
