Mechanical control system of single-rotor model helicopter

Abstract

The invention relates to a mechanical control system of a wireless remote single-rotor model helicopter, comprising a pair of cavity-mixing rocker arms which are respectively arranged on two sides of a rotor wing clamp, and the cavity-mixing rocker arms on two sides of the rotor wing clamp can be rotatably connected by a shaft hole in the middle of the rotor wing clamp, wherein two control pointsare respectively arranged at two ends of each cavity-mixing rocker arm; and a first pair of control points of which opposite angles are opposite in the pair of cavity-mixing rocker arms is controlledby periodical moment transferred from a servo to an inclined tray combination, while a second pair control points of which opposite angles are opposite are controlled by a balance system of the helicopter, and the second pair control points controlled by the balance system and the first pair of control points controlled by the inclined tray combination mutually move by pivots. In addition, the mechanical longitudinal axis of the helicopter is positioned in rotating direction range of 70 degrees to 20 degrees of an inverse rotor wing of the longitudinal axis of a model helicopter, while the mechanical lateral axis of the helicopter is positioned in rotating direction range of 70 degrees to 20 degrees of an inverse rotor wing of the lateral axis of a model helicopter. The single-rotor modelhelicopter with the control system is relatively stable and easy to control.

Description

technical field [0001] The invention relates to a radio-controlled model helicopter, in particular to a mechanical control system of a radio-controlled four-channel single-rotor model helicopter. Background technique [0002] Radio-controlled single-rotor model helicopters, whether it is a single-rotor model helicopter controlled by four-channel or more-channel radio-controlled equipment, currently generally use the "Bell-Sila" hybrid control method. The manipulation process of the "Bell-Silla" control system is: according to the instructions of the electronic receiver in the radio remote control device, the servo machine manipulates the non-rotating swashplate to tilt in the specified direction through the connecting rod; while the rotating swashplate is driven by the fork , rotate synchronously with the main shaft on the non-rotating inclined-inclined plane, during this process, the transmission torque of the servo machine is converted into a periodic torque; the rotating ...

Problems solved by technology

[0006] Therefore, when aviation model enthusiasts are learning single-rotor model helicopters, they can only choose to learn the difficult-to-master "Bell-Sila" mode single-rotor model helicopters

In fact, the suitable large rudder volume and sensitive handling characteristics of the "Bell-Sila" model single-rotor model helicopter have become an obstacle instead. The control technology of this mode is complicated. —Hovering is difficult to master, let alone difficult stunts with a large amount of rudder
