ABSTRACT:
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 end in fluid communication with the powerplant and multiple downstream ends including flanges connected to upstream ends of corresponding intermediate ducts. The aircraft further includes multiple covers connected to corresponding manifold flanges and covering corresponding intermediate duct flanges. The aircraft also includes multiple absorbers positioned between corresponding intermediate duct flanges and manifold flanges and between the intermediate duct flanges and corresponding covers to control movement of the intermediate duct flanges.
