Tiltrotor aircraft with inboard wing mounted fixed engine arrangement

摘要

A rotor system (108, 109) for tilt rotor aircraft (100) comprises an engine (145) disposed at a first fixed position on a wing member (105), and a prop-rotor pylon (119) mechanically coupled to the engine (145) along a drive path extending through the wing member (105). The engine (145) is disposed adjacent a fuselage (103) of the tilt rotor aircraft (100), and the prop-rotor pylon (119) is configured to selectively rotate between a vertical position and a horizontal position. The prop-rotor pylon (119) is coupled to a plurality of rotor blades (110).
