Abstract

The invention relates to a remote-control model helicopter balanced system which is suitable for balance control of a single-rotor model helicopter. The model helicopter comprises a main shaft, a rotor clamper which is arranged on the main shaft, and a pair of rotors which is arranged on the rotor clamper. The balanced system comprises a pair of control swinging arms, a balance bar which is connected to the main shaft, and a pair of balance weights which are arranged on both ends of the balance bar, wherein the pair of control swinging arms is rotatably connected to both sides of the rotor clamper through matching of axle holes in the middle of the control swinging arms and convex shafts on both sides of the rotor clamper; universal link points are formed on both ends of the control swinging arms, wherein a link point on the first end is controlled by a pair of first connecting bars through the balance bar, and a link point on the second end is controlled by a pair of second connecting bars through a control system; and the horizontal included angle between the axial line of the balance bar and the axial line of the rotor is between 25 and 65 DEG. The balanced system can improve the balance quality of the model helicopter.

Description

technical field

[0001] The invention relates to a remote-controlled model helicopter, in particular to a balance system for a single-rotor remote-controlled model helicopter. Background technique

[0002] Remote control model helicopters are basically the same as real helicopters, but they are obviously different in structure. At present, the control methods of the helicopter include the Bell method, the Sila method and the Bell-Sira hybrid method.

[0003] The Bell method is mostly used in real helicopters. Its typical feature is the direct control of the blade angle of the rotor. There is no stabilizing fin, and there is a counterweight on the leading edge of the rotor. More modern helicopters do not even have a counterweight, but the rotor can As a waving movement, when the helicopter encounters unstable airflow interference during travel, the changing aerodynamic load will not be transmitted to the fuselage, and the turbulence of the helicopter will be small. The chara...
