Abstract

According to the present invention, to smoothly operate an unmanned air vehicle having one internal combustion engine and a plurality of rotors, a rotation direction of each of the rotors can be easily controlled clockwise or counterclockwise. To achieve this, in a process of mounting a bevel gear (40) and another bevel gear (30) on a power axis horizontally appearing to convert a power transmission direction in a vertical direction, a mounting position and a mounting direction of the bevel gear (30) are changed to easily change a rotation direction of an axis to which power is transmitted.

Description

가변 기어 시스템{variable gear system}Variable gear system [0001]

본 발명은 다수의 회전익을 사용하는 멀티콥터 형 무인 비행체에서 각각의 회전익의 회전방향 제어를 위한 것으로 기존 모터 방식의 경우 전극의 극성을 이용하여 각각의 회전방향을 쉽게 제어하지만 하나의 내연기관을 사용하는 멀티콥터의 경우 각각의 회전익 회전방향을 제어하는 것이 모터방식과는 다르기 때문에 이를 용이하게 하기 위해 개선된 기어장치에 관한 것이다.
The present invention is for controlling the rotation direction of each rotor blade in a multi-copter type UAV using a plurality of rotor blades. In the conventional motor type, the rotation direction of each rotor is easily controlled by using the polarity of the electrodes. However, In the case of a multi-copter, it is different from the motor type to control the direction of rotation of each rotor blade.

현대에는 많은 무인 비행체의 연구와 개발이 진행되고 있으며 산업 곳곳에서 운용되고 있다. 특히 항공산업에서 무인항공기(UAV, Unmanned Aerial Vehicle) 및 무인 비행체는 그 응용 분야가 다양한데, 기존의 군사용으로 활용되는 무인정찰기와 무인전투기에서 더 나아가 재난 감시, 구호, 기상관측, 농업 항공방제, 민간용 항공촬영, 엔터테인먼트 등의 분야에서 사용되고 있으며 더 많은 분야로 확장되고 있는 추세이다.Many unmanned aerial vehicles are being researched and developed in modern times and are being operated in various industries. Unmanned aerial vehicles (UAVs) and unmanned aerial vehicles (UAVs) have a wide range of applications in the aviation industry. They are also used in conventional unmanned reconnaissance aircraft and unmanned fighter planes for disaster monitoring, relief, meteorological observation, Aerial photography, entertainment, and the like, and is expanding to include more fields.

현재 상용화 된 무인 비행체 중 특히 멀티 로터를 구비한 멀티콥터의 경우 다수개의 모터를 이용하여 짝수개의 프로펠러를 구성하고 프로펠러의 개수에 따라 절반은 정방향의 회전을, 나머지 절반은 역방향의 회전으로 서로 회전방향을 달리하여 회전반력을 상쇄시키는 구조를 이용한 구동방식 또는 멀티콥터 몸체에 기어를 장착하여 엔진을 이용한 구동방식이 사용되고 있다. In the case of a multi-copter equipped with a multi-rotor among commercialized unmanned aerial vehicles, in particular, an even number of propellers are constructed using a plurality of motors. In accordance with the number of propellers, half is rotated in the forward direction and the other half is rotated in the reverse direction A driving system using a structure for canceling a rotational reaction force or a driving system using an engine equipped with gears on a multi-copter body is used.

종래의 다수개의 모터를 이용하여 프로펠러를 회전시키는 경우 각각의 모터의 전극을 바꿔 회전방향을 제어해야 하고, 배터리를 이용하기 때문에 전력량의 한계로 인해 비행시간이 짧은 단점이 있고, 다수개의 엔진을 이용하여 회전시키는 경우에는 역방향의 엔진을 사용하여야 하는데 이는 엔진에 무리를 주어 결함을 야기시키는 원인이 되기도 한다.
When the propeller is rotated using a plurality of conventional motors, it is necessary to control the direction of rotation by changing the electrodes of the respective motors. Since the battery is used, there is a disadvantage in that the flight time is short due to the limitation of the amount of electric power. The engine must be used in the reverse direction, which may cause the engine to be overloaded and cause defects.
