Design of tilting drive mechanism for a tilting wing aircraft
Abstract
Tilting wing aircraft is a new type of aircraft which integrates fixed wing and helicopter. It has the ability of normal helicopter to take off and land vertically and hover in the air. It also has the ability of high-speed cruise of turboprop aircraft and has strong maneuverability. Its structure mainly includes rotor shaft， rotary engine， swing engine， swing transmission system， etc.
In this design， combined with the given performance index parameters， the overall design scheme of the tilting mechanism of the tilting wing aircraft is drawn up. The performance parameters of each component in the tilting driving mechanism of the tilting wing aircraft are calculated in detail， and the geometric structure dimensions of each component and the main structural parameters of each part are determined， which has practical significance.
Keywords:Tilting wing； two degree of freedom rotation； swing transmission
