Wing large-angle tilting mechanism for small-size tilting wing type aircraft

Abstract

The invention relates to a wing large-angle tilting mechanism for a small-size tilting wing type aircraft. The wing large-angle tilting mechanism for the small-size tilting wing type aircraft comprises a wing, a hinge, a spherical hinge support, a ball-head tension rod assembly, a steering engine plate and a servo steering engine, wherein the wing is connected with an aircraft body through a tilting main shaft of the wing; the servo steering engine is fixed to the aircraft body; the steering engine plate is inserted on an output shaft of the servo steering engine, engagement teeth are arrangedbetween the steering engine plate and the output shaft of the servo steering engine, effective transmission of torque is ensured, and screws are adopted for connection so that fastening can be ensured; one end of the ball-head tension rod assembly is connected with the steering engine plate through the spherical hinge support, the other end of the ball-head tension rod assembly is connected withthe wing through the spherical hinge support, and the spherical hinge support is connected with the steering engine plate and the wing through the screws on the plane; the length of a pull rod can beadjusted according to the actual condition; and a hinge shaft serves as the tilting main shaft of the wing. According to the wing large-angle tilting mechanism for the small-size tilting wing type aircraft, the space four-link mechanism is adopted, the steering engine serves as a power device, the output torque needed by the steering engine is effectively reduced, the structure is simple, manufacturing is easy, high assembly precision is not needed, and the wing large-angle tilting mechanism for the small-size tilting wing type aircraft is a stable and practical tilting device.

Description

technical field [0001] The invention belongs to the technical field of aircraft wing tilting, and is mainly used in the realization of large-angle tilting of the wings of a small tilting wing aircraft. It is a mechanism that can drive the entire wing to tilt within a relatively large angle, and can Applied to small tilting wing aircraft. Background technique [0002] For the tiltrotor aircraft represented by the V-22 Osprey, there are certain defects. In the vertical take-off and landing state, the large downwash generated by the wing cover causes unnecessary energy loss. Thereby a kind of tilting-wing type aircraft in which the wings and the engine are integrally tilted has appeared. For this type of aircraft, the structural design to realize the integral tilting of the wings has become a key issue. Aiming at this problem, the present invention proposes a design scheme of the overall tilting mechanism of the wing. [0003] For small tilting wing aircraft, the mutual conve...
