Description

Technical Field

[0001] The utility model relates to the technical field of autogyro pre-rotation, in particular to a gear clutch pre-rotation device. Background Technique

[0002] An autogyro is an aircraft with affordable price and excellent flight performance.

[0003] During the flight of an autogyro, the lift is mainly provided by the rotor at the top of the fuselage. During level flight cruise, the wind blowing towards the autogyro pushes the rotor to rotate automatically, and the automatic rotation of the rotor generates lift. During the takeoff stage of the autogyro, it is necessary to pre-rotate the top rotor to quickly generate lift, so as to reduce the distance of taxiing on the runway and achieve rapid takeoff.

[0004] Chinese Patent with the patent number CN202311001276.7 proposes an autogyro pre-rotation system. From its structure, it can be seen that the existing autogyro pre-rotation structures all achieve the drive / idle rotation of the pre-rotation system by adding a clutch structure to the pre-rotation system. This design is relatively complex and costly. Content of the Utility Model

[0007] Preferably, a limit seat is sleeved at the bottom of the gear.

[0008] Preferably, the top of the rotor disc is provided for the rotor blades of the autogyro.

[0009] Preferably, the top of the motor frame is a horizontal plane.

[0010] The utility model provides a gear clutch pre-rotation device. Compared with the prior art, the utility model has at least the following technical effects: the utility model directly drives the rotor disc through a pre-rotation motor, and the driving force for pre-rotation is large. Moreover, the rotor disc is pulled to engage with or disengage from the gear through a tilting balance rod and a tilting push rod, so as to quickly realize the pre-rotation and braking of the autogyro. In addition, the overall structure is simple, easy to manufacture, and has a low manufacturing cost. Brief Description of the Drawings
