Abstract

A rotational force generated by rotating a propeller to obtain lift required for flight of a drone generates fine vibration while receiving resistance of air. The vibration is transmitted to a wing to exist as a vibration wave. The vibration wave reduces flight efficiency of the wing. The present invention enables an end of the wing to be bent at about 30 degrees to reduce the vibration wave transmitted to the wing to stabilize a flow of the wing to increase about 30% of flight efficiency.

Description

드론의 양력 증가 장치에 관한 방법 및 장치{Increasing Device ＆ Method of Drone's upward force}Technical Field [0001] The present invention relates to a method and an apparatus for increasing the lifting force of a drone,

본 발명은 드론의 비행에 필요한 양력 발생 장치인 프로펠러의 모양변경 및 양력을 증가시키기 위한 장치에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a device for increasing a shape and a shape of a propeller, which is a lift generating device necessary for flying a drones.

원심력을 이용한 드론의 프로펠러 날개 안정화와 공기의 흐름을 증가시키는 공기역학의 원리를 이용하였다.The principle of aerodynamics is used to stabilize the propeller blades of the drones using centrifugal force and to increase the air flow.

드론의 비행에 필요한 양력을 얻는 과정에서 의외의 에너지 손실이 많이 발생한다.In the process of obtaining the lift required for the flight of the drones, many unexpected energy losses occur.

프로펠러가 회전하면서 생기는 진동에 의하거나 공기흐름 중 일부 실효로 인해 에너지 손실이 발생한다.Energy loss is caused by vibration caused by rotation of the propeller or due to some effect of air flow.

도 1에서 이중날개 꺽기(1)처럼 날개 끝을 약 30˚가량 위로 꺽음As shown in FIG. 1, the wing tip is bent about 30 degrees upward like a double wing (1).

도 2에서 공기집적 장치(2)와 같이 드론의 날개 위에 꼬깔모양의 원통을 부착2, a coin-shaped cylinder is mounted on the wing of the dron like the air accumulator 2

드론(무인 조정 비행기)는 비행을 위하여 프로펠러를 회전시켜 양력을 발생시킨다.Drone (unmanned airplane) generates lift by rotating the propeller for flight.

이와 같이 발생시킨 양력을 이용하여 상승과 하강 전,후·좌·우 방향으로 비행력을 얻는다Using the lift generated in this manner, the flight force is obtained before, after, and after,

양력을 얻기 위해 프로펠러가 회전하면서 생기는 회전력은 공기의 저항을 받으면서 미세한 진동을 일으키며, 이 진동은 날개에 전달되어 진동파로써 존제하게 된다. 이러한 진동파는 각 날개의 비틀림을 발생시키고 이로인해 많은 비행 효율의 감소로 이어진다.The rotational force generated by the rotation of the propeller in order to obtain the lift is caused by the resistance of the air, which causes a slight vibration, which is transmitted to the wing and becomes a vibration wave. These vibration waves cause twisting of each wing, which leads to a decrease in the flying efficiency.

본 발명은 날개의 끝을 약 30˚가량 꺽음으로 인한 원심력을 발생 시킨다.The present invention generates a centrifugal force due to bending of the end of the wing by about 30 degrees.

이 원심력은 각 날개의 흐름을 안정화 시켜줌과 동시에 날개의 직선성을 회복 시켜준다.This centrifugal force stabilizes the flow of each wing and restores the linearity of the wing.

또한 원심력에 대한 회전속도의 증가 효과를 기대할 수 있다.Also, the effect of increasing the rotation speed with respect to the centrifugal force can be expected.

날개끝을 꺽음으로써 프로펠러의 진동과 비틀림을 최소화한 안정된 회전은 무게 균형의 적합화를 통하여 약 30%의 비행 효율 증가를 가져올 수 있게 하는 것이 본 발명의 특징이다.It is a feature of the present invention that stabilized rotation with minimized vibration and torsion of the propeller by deflecting the wing tip can bring about 30% increase in flight efficiency through adaptation of the weight balance.

또한, 꼬깔 모양 원통인 공기 집적 장치의 특성으로는 드론날개에서 생선되는 공기양력의 증폭 효과이다.Also, the characteristics of the air accumulating device, which is a cylindrical shape, is the amplifying effect of the air lift generated from the drones.

이는 공기 유체 역학상 공기가 좁은곳에서 넓은 곳으로 흐를 때 공기의 흐름이 빨라지고 이 때 생기는 대기압 차이에 의한 공기유체 효과를 이용한 것이다.This is due to the effect of air fluid due to the difference in atmospheric pressure caused by the flow of air when the air flows from a narrow space to a wide space.

도 2는 공기 집적 장치(2)를 나타낸 도면이다.1 is a view showing a double wing bend 1;
