An aircraft is disclosed having an engine and a propeller mounted to a fuselage. An empennage mounts to the aircraft and includes first and second horizontal stabilizers separated by a distance greater than the diameter of a stream tube of the propeller at the horizontal stabilizers. A rudder extends between the horizontal stabilizers and is positioned within the stream tube of the propeller. A bulkhead is positioned rearward from the cockpit and oriented perpendicular to a longitudinal axis of the airframe. A tailboom and engine are mounted to the airfr...


1. A rotorcraft comprising: an airframe defining a center plane extending in longitudinal and vertical directions;a rotor mounted to the airframe and defining a rotor thrust vector;a propulsion source mounted to the airframe and defining a propulsion thrust vector;a plurality of fuel tanks distributed in one or more of laterally opposed positions, longitudinally opposed positions, and vertically opposed positions;the airframe further comprises a pair of tailbooms and an empennage mounted to the airframe by means of the tailbooms;the plurality of fuel tan...
