Aircraft including a powerplant mounted on an airframe and a rotor/wing rotatably mounted on the airframe. The rotor/wing has multiple blades extending outward from roots adjacent the airframe to tips opposite the roots and having internal conduits extending between inlets adjacent the roots and downstream outlets. The aircraft also includes multiple intermediate ducts having upstream ends including flanges and downstream ends slidably and pivotally connected to corresponding blade inlets. Moreover, the aircraft includes a manifold having an upstream en...


What is claimed is: 1. An aircraft comprising: an airframe having a fuselage extending longitudinally between a forward end and an aft end opposite the forward end and a set of fixed wings extending laterally from the fuselage; a power plant mounted on the airframe producing exhaust during operation of the aircraft for powering the aircraft; a rotor/wing assembly rotatably mounted on the airframe for selective rotation with respect to the airframe, said rotor/wing assembly having a plurality of blades, each blade of said plurality of blades extending ou...
