Small-angle tilting mechanism of engine for small tilt rotor aircraft

Abstract

The invention discloses a small-angle tilting mechanism of an engine for a small tilt rotor aircraft. The small-angle tilting mechanism of the engine comprises a tilting main shaft, a steering engine fixing frame, a servo steering engine, a steering engine plate, a ball head tie rod assembly, left and right engine bases, engine base fastening bolts, an engine fixing frame, a rack fastening bolt and an engine base rotating bearing, wherein the tilting main shaft is connected with a machine body; the servo steering machine is connected to the tilting main shaft through the steering engine fixing frame, and is connected with the steering engine fixing frame through bolts; a take-up device is arranged on the steering engine fixing frame and used for loading, unloading and moving the steering engine fixing frame on the tilting main shaft; the steering machine plate is inserted into an output shaft of the servo steering machine; one end of the ball head tie rod assembly is connected with the steering machine plate; the other end of the ball head tie rod assembly is connected with the left engine base; the left engine base and the right engine base are connected to the tilting main shaft through engine base rotating bearings; the axial positioning and circumferential positioning of the left engine base and the right engine base are achieved through the engine base rotating bearings; and the engine fixing frame is fixed on the left engine base and the right engine base through four rack fixing bolts.

Description

technical field [0001] The invention belongs to the technical field of aero-engine tilting, and in particular relates to an engine small-angle tilting mechanism for a small tilting rotorcraft. It is a mechanism that can drive the engine to tilt within a small angle, and can be applied Small tilt rotor aircraft. Background technique [0002] For some small tiltrotor aircraft or general two-axis aircraft, the stability of the pitch and yaw attitude in the hovering state must be achieved by tilting the engine within a certain range to make the propeller tension line deviate from the center of gravity. The stability of attitude requires a set of sensitive and reliable tilting mechanism to execute the control commands issued by the controller. [0003] For the tilting rotorcraft, there is a set of tilting mechanism itself so that the engine and the propeller can rotate within a range of about 90 degrees, but if this mechanism is used to execute the control command of the control...
