Abstract

The invention provides a tilting mechanism and a sealing mechanism. A traditional tilt-rotor aircraft employs a structure mode of integral tilting of an engine and rotor wings, and the structure mode has disadvantages in practice in spite of the advantage of simple and direct structure; a conventional tilting mode which arranges an engine and a tilting structure in a parallel and non-coaxial manner can overcome the disadvantages of the mode of integral tilting of the engine and the rotor wings and overcome problems in sealing of the tilting structure, but the biaxial arrangement manner which allows the engine and the tilting structure to be separated also has disadvantages in practice since a transverse power transmission structure has to be additionally arranged. The invention provides a coaxial arrangement manner for an engine and a tilting structure to overcome defects caused by existence of the transverse power transmission structure in the non-coaxial arrangement manner. The invention also provides a sealing mechanism to overcome problems in sealing of the coaxially arranged tilting structure.

Description

Technical field: [0001] The invention relates to the field of aviation, in particular to: a tilting mechanism. Background technique: [0002] At present, only the U.S. Osprey v-22 and subsequent models (V-280) can be used in the field of aviation. The vertical take-off and landing of the V-22 is achieved by pulling up the body from a horizontal state to a state of upward deflection of 90 degrees (greater than 90 degrees) through two engines installed at the ends of the double wings. Although the integral tilting of the engine and the rotor has the advantages of simple and direct structure, at the same time, the overall tilting of the engine and the rotor increases the difficulty of manipulation, and the volume and weight of the deflection support structure, deflection control mechanism and related structures are relatively high. There are some practical shortcomings such as the vibration of the engine and rotor, the overall large volume of the engine in a vertical state, an...
