Four-channel transverse dual rotor helicopter

Abstract

The present invention provides a four-channel transverse dual rotor helicopter, comprising a frame with a battery encapsulated inside it, an empennage breadthwise located at the afterbody of the frame, an aircraft wheel assembly fixed at the bottom of the frame, wherein, two cantilever bars of left and right are connected to the frame, breadthwise located at the two sides of the frame, and capable of rotating around axes of themselves; the left and right cantilever bars are separately via a group of linkage mechanism connected to left and right steering engines located at the frame for driving the left and right cantilever bars to rotate around axes of themselves; the ends of the left and right cantilever bars are separately provided with a group of rotor wing mechanism; the motors in the two groups of rotor wing mechanism, and the left and right steering engines are connected to a signal receiver located in the frame; the motors are variable speed motors. The present invention is easy to control, so as to make the beginner without controlling foundation also capable of controlling the helicopter to fly stably. At the same time, the simplified mechanical structure of the helicopter reduces the production cost, also greatly improves the performance stability of the helicopter.

Description

BACKGROUND OF THE INVENTION[0001]The present invention relates to technical field of telecontrol aeromodelling control, especially relates to a structure of four-channel transverse dual rotor helicopter.[0002]Currently, the transverse dual rotor helicopter of telecontrol aeromodellings is a vertically rising and falling device using rotor wings as its main lift force source, and is different from the fixed wing model aircraft. Generally, the fixed wing model aircraft is made comparatively easy to control because of the structure of the type of aircraft, so every people with ordinary response speed can deal with it; and a dual rotor helicopter has more control surfaces, so that the complicated flight operation of a transverse dual rotor helicopter is hard to control without a lot of exercises and the help of electronic devices.[0003]To control the flight attitude of a transverse dual rotor helicopter, normally changing the angle of the rotor wings at the two sides is adopted; general...

AI Technical Summary

Benefits of technology

[0004]To solve the technical problems of the existing transverse dual rotor helicopter with complicated structure and operation, the present invention provides a transverse dual rotor helicopter with simple structure and operation.

[0013]In the present invention, the helicopter rotor wings have only two angle variations of inclining forward or inclining backward, and the helicopter is controlled to fly forward, fly backward or change flight direction by inclining the rotor wing forward or backward. The ascending and descending of the model helicopter are controlled by simultaneously increasing or decreasing the rotation speeds of the motors at the two sides; the inclining of the helicopter is controlled by controlling the variation of the reaction torques via controlling the rotation speeds of the two motor, so as to change the flight direction of the helicopter. Comparing with conventional art, the present invention simplifies the operation to the rotor wings, comparatively simplifies the mechanical structure driving the rotor wing angle to change, reduces the production cost, and also reduces the difficulty of controlling the helicopter, so as to make the beginner without controlling foundation also capable of controlling the helicopter to fly stably. At the same time, the simplified mechanical structure of the helicopter also greatly improves the performance stability of the helicopter.

Problems solved by technology

Generally, the fixed wing model aircraft is made comparatively easy to control because of the structure of the type of aircraft, so every people with ordinary response speed can deal with it; and a dual rotor helicopter has more control surfaces, so that the complicated flight operation of a transverse dual rotor helicopter is hard to control without a lot of exercises and the help of electronic devices.

To control an existing transverse dual rotor helicopter to finish various attitudes, changing the rotor wing angle is required by all, so that it is comparatively hard to control, and the mechanical structure controlling the rotor wing angle to change will also be comparatively complicated.

However, miniaturizing telecontrol aeromodellings has gradually becomes a trend, and the consumers mainly are beginners, so this kind of products must be cheap; however complicated mechanical structure and multiple gyroscopes adopted will certainly lead to the increasing of cost, so it is not good for the popularization of this kind of products, and the complicate structure of existing transverse dual rotor helicopter also is not good for controlling the helicopter.
