ENGINE AND ROTATABLE PROPROTOR CONFIGURATIONS FOR A TILTROTOR AIRCRAFT

摘要

A tiltrotor aircraft (201) includes a propulsion system (211) with a fixed engine (223) and a rotatable proprotor (215). The engine (223) is located below the wing (209) of the tiltrotor aircraft (201), and the rotatable proprotor assembly (215) is mounted on the top surface of the wing. The engine (223) and proprotor assembly (215) are connected via a series of one or more gearboxes (310, 322, 330) that route the engine output from the engine (223) to the proprotor (213).
