Problems solved by technology

But the model is different, it is impossible to control precisely, only fixed speed, so it often causes the fuselage to spin, unable to maintain balance and stabilize the flight
[0007] 3. The helicopter can move forward and backward because of a complex mechanism on the main propeller, and it is impossible to copy it on the model, so it can only be replaced by a simple device
Therefore, it is common for helicopter models to go up and down in the vertical direction, but it is not easy to move forward and backward flexibly.

Embodiment Construction

[0017] Such as figure 2 and image 3 As shown, there are two helicopter propellers: the left propeller 5 with a channel and the right propeller 4 with a channel are arranged side by side. The two paddles are driven by a motor 9, and the motor 9 directly drives the left and right propellers through a conveyor belt. The motor rotates clockwise, which drives the propeller to rotate clockwise. The torque produced by the left propeller 5 is F1, and the torque produced by the right propeller 4 is F2. That is to say, when the sculls rotate, no torque is generated, which forms the basis for stable flight.

[0018] The double-channel propeller and the power system can rotate around the shaft to form a change in the tension line and complete the functions of vertical ascent, forward and backward. The effect of enclosing the propeller with the duct is that a larger lift force can be obtained under a smaller diameter of the propeller, and the propeller is not easily damaged due to ...

Abstract

The invention discloses an airplane model which comprises an airplane body. The airplane model is characterized by further comprising a left propeller and a right propeller which are arranged on the left side and the right side of the airplane body and in a duct. The propellers are driven by a motor to rotate. A fixed wingstub is connected to the tail of the airplane body and provided with a vertical tail, and a horizontal tail is mounted on the vertical tail. The airplane model has the advantages of a helicopter and a common airplane, is provided with small propellers, and is easy to operate, capable of vertically taking off and landing and flexible.

Description

technical field [0001] The invention relates to an airplane model. Background technique [0002] The current remote control helicopter model adopts the same aerodynamic layout as the helicopter: such as figure 1 As shown, the main propeller 1 is the source of lift, and a tail rotor 2 is provided to offset the torque of the main propeller. Without this tail rotor, the helicopter fuselage will rotate continuously and cannot fly. [0003] The main propeller rotates clockwise, and according to the principle of momentum moment balance, the fuselage will rotate counterclockwise, but due to the pulling force of the tail rotor, the torsion force of the fuselage is offset, so that the fuselage remains in a balanced state. The remote control helicopter model made according to the principle of helicopter aerodynamics has developed rapidly in recent years and has become a high-end fashion toy. [0004] But this model has the following flaws: [0005] 1. The main propeller is too...
