Model airplane helicopter

Abstract

The invention discloses a model airplane helicopter, which comprises an airframe. A main shaft and a hollow shaft are arranged in the airframe; the main shaft is arranged in the hollow shaft; the hollow shaft is provided with a primary airscrew; the main shaft is provided with a secondary airscrew; an electronic gyroscope is arranged in the airframe; a swash plate and a steering engine are arranged below the primary airscrew; the swash plate is connected with the steering engine through a connecting rod; the swash plate is provided with a turning plate; the turning plate is linked with the primary airscrew; a headstock cap is arranged above the secondary airscrew; and the secondary airscrew is linked with the headstock cap through an elastic adapting piece. Through arranging the electronic gyroscope in the airframe, the flight attitude of the model airplane helicopter can be automatically detected and the helicopter is automatically controlled, and meanwhile, a balancer bar is replaced by the elastic adapting piece to keep the stability of the helicopter; and as the balancer bar is not needed, the load of the model airplane helicopter is relieved.

Description

technical field [0001] The invention relates to a model airplane, in particular to a model airplane helicopter. Background technique [0002] Model aircraft, a model aircraft that can fly in the air, among which model aircraft helicopters are more common. The development of model airplanes lies in its interest and knowledge, which cannot be compared with simple airplane models that cannot fly, especially model airplane helicopters, which are loved by more and more people, not limited to children. In view of the marketability of aircraft model helicopters, developers continue to develop aircraft model helicopters with higher technology. [0003] Most of the current model airplane helicopters have a set of propellers, which are weak in wind resistance when flying outdoors, and difficult for novices to control, which may easily cause damage or damage to the model airplane helicopters. Some aircraft model helicopters are equipped with two sets of propellers, which enhance the ...

AI Technical Summary

Problems solved by technology

However, when the aircraft model helicopter is disturbed by the outside world (such as strong wind or collision), the flight action will deviate, and it will take a certain amount of time for the balance bar to correct the flight action.

In addition, the balance bar itself is heavy, and the model airplane helicopter has high requirements for its own weight, and its own overweight has a great impact on the flight of the model airplane helicopter, which is not conducive to flight
