Technical Field

[0001] The invention relates to the technical field of autogyro, in particular to a rotor module. Background Art

[0002] An autogyro is a rotorcraft that uses the relative airflow during forward flight to generate lift by rotating the rotor. The rotor system mainly provides lift and pitch and roll attitude control for the autogyro, and is a key component of the autogyro.

[0003] The existing rotor system design, such as the Chinese patent application with patent number "CN202020207621.8", is designed to have a fixedly connected fuselage frame for the rotor system to be installed. The rotor system of this design is overall bloated and the structure cannot be disassembled. Summary of the invention

[0004] In order to solve the above problems, an object of the present invention is to provide a rotor module with high structural integration and easy disassembly.

[0005] The following scheme is adopted in the embodiment of the present invention: a rotor module is hingedly set on the mast of the autogyro, and the rotor module has a built-in pre-rotation motor and a tilt-rotation servo. The pre-rotation motor drives the rotor blades on the rotor module to pre-rotate, and the tilt-rotation servo drives the rotor module to tilt back and forth along the horizontal plane.

[0006] Preferably, the rotor module also includes a module mounting seat, a rotor support, a pre-rotation gear and a rotor clamp seat. The module mounting seat is arranged on the mast, and the rotor support is hingedly arranged on the module mounting seat. A pre-rotation gear is sleeved on one side of the rotor support. The rotor support is provided for the pre-rotation motor to be set. The pre-rotation motor engages the pre-rotation gear and drives the pre-rotation gear to rotate. The top of the pre-rotation gear is fixedly set by the rotor clamp seat, and a rotor blade is detachably set at the front and back of the rotor clamp seat.

[0007] Preferably, the two tilting servos are arranged on both sides of the module mounting seat, and the tilting servos are connected to and drive the rotor support to tilt.

[0008] Preferably, the module mounting seat is a fork-shaped member, and the bottom of the module mounting seat is detachably arranged on both sides of the mast.

[0009] Preferably, the tilt servo is connected to the module mounting seat via a driving rod, and the tilt servo rotates the driving rod to drive the module mounting seat to tilt forward and backward; the two tilt servos and the driving rods connected thereto are symmetrically arranged on both sides of the module mounting seat.

[0010] The present invention provides a rotor module. Compared with the prior art, the present invention utilizes a pre-rotation motor to directly drive the rotor blades to pre-rotate, which greatly simplifies the pre-rotation system of the autogyro, and improves the efficiency of the pre-rotation while reducing the complexity of the structure. In addition, the tilt angle of the rotor blades of the rotor module is adjusted by the tilt servo to simplify the overall rotor control. The present invention proposes a streamlined rotor module, which is highly integrated while fully realizing rotor pre-rotation and rotor tilt, thereby realizing modularization of the rotor of the autogyro, facilitating installation and disassembly, and also facilitating the testing of autogyro with different requirements.

[0016] See also Figures 1 to 3 A rotor module is hingedly arranged on a mast 2 of an autogyro 1, and the rotor module has a built-in pre-rotation motor 3 and a tilting servo 4. The pre-rotation motor 3 drives the rotor blades 5 on the rotor module to pre-rotate, and the tilting servo 4 pushes the rotor module to tilt back and forth along the horizontal plane.

[0017] The present invention utilizes the pre-rotation motor 3 to directly drive the rotor blades 5 to pre-rotate, which greatly simplifies the pre-rotation system of the autogyro, and improves the efficiency of the pre-rotation while reducing the complexity of the structure. In addition, the tilt angle of the rotor blades 5 of the rotor module is adjusted by the tilt servo 4 to simplify the overall rotor control. The present invention proposes a streamlined rotor module, which is highly integrated while fully realizing rotor pre-rotation and rotor tilt, and realizes the modularization of the rotor of the autogyro, which is easy to install and disassemble, and is also convenient for testing of rotorcraft with different requirements.

[0018] The rotor module also includes a module mounting seat 6, a rotor support 7, a pre-rotation gear 8 and a rotor clamp seat 9. The module mounting seat 6 is arranged on the mast 2, and the rotor support 7 is hingedly arranged on the module mounting seat 6. The pre-rotation gear 8 is sleeved on one side of the rotor support 7. The rotor support 7 is provided for the pre-rotation motor 3 to be set. The pre-rotation motor 3 engages with the pre-rotation gear 8 and drives the pre-rotation gear 8 to rotate. The top of the pre-rotation gear 8 is fixedly set by the rotor clamp seat 9, and a rotor blade 5 can be detachably set at the front and back of the rotor clamp seat 9.

[0019] In order to further improve the stability of controlling the inclination of the rotor blade 5, the two tilting servos 4 are arranged on both sides of the module mounting seat 6, and the tilting servos 4 are connected to and drive the rotor support 7 to tilt.

The two tilting servos 4 and the driving rods 40 connected thereto are symmetrically arranged on both sides of the module mounting seat 6. The module mounting seat 6 is provided with a plurality of mounting holes for the tilting servo 4 to be arranged. The tilting servo 4 can change the torque generated by the driving rod 40 by connecting the driving rods 40 of different lengths to adapt to the driving of rotor blades 5 of different sizes.
