Description

Technical Field [0001] The present invention relates to a rail type protection ring and a weight car for changing the traveling direction of a copter type drone,

This technology is about the next generation aeronautical technology, a copter type unmanned aerial vehicle (drone). When the direction of the drone is changed, the movement of the four weight cars running on the rail-shaped ring protecting the outer edge of the rotor blade, It is a mechanical structure and its working principle that changes the direction of progress by using the slope of the gas with respect to the perpendicular, which is the gravity direction, and the dispersion of the force from the movement of the center of gravity.

As a background of the present invention, when a plurality of accessory bodies move in different angles on a circular protective ring, as shown in FIGS. 1 and 2, the sum of the weight of those members located at the origin (0, 0) The center-of-gravity point G2 (0, 0) is changed to the shifted center-of-gravity point G2 (Lx, Ly) Calculate the difference between the center of gravity G2 (Lx, Ly) and the slope of the gas, and calculate the variance of the force. Therefore, the drones should carry out their purpose by calculating the moving speed, the rising speed and the direction change based on these coordinate points. In addition, the four weight cars are not fixed at the designated position, but the corners must change their center of gravity while moving at high speed with the target coordinates of the corners on the circular ring. Therefore, by the centrifugal force generated at this time or external force The shape of the roller of the weight car and the sectional shape of the rail are physically determined so that the weight car can not be detached from the protection ring. The weight car must constantly move at a high speed so as to control the center, direction and speed of the dron even if the dron's posture is dispersed due to a change in the movement and inclination of the entire gas or a force imbalance from the outside It is a core technology.

1. The existing drones are structurally compact, require a small operating range and low operating time (20 to 30 min), require a relatively large amount of energy to move the gas, and have a short lifetime of the gas. And to make the drones large, industrial, and environmentally friendly.

2. Like conventional helicopters, these devices do not turn the shaft of the rotor blades like the front wheels of a motorcycle in order to change direction, but rather provide direction and safety by an external device, The weight center is moved using four weight cars without changing the direction, and the horizontal and vertical wind forces of the inclined gas are used to relatively save the fuel and determine the traveling speed and direction.

3. There is a limit to determining the direction and speed by turning the blade rotating shaft like a conventional unmanned aerial vehicle. In other words, the maximum angle of the shaft is about 10 degrees when you look at the existing copter type drone. It determines the speed and direction within it. However, in the present invention, the inclination of the drone can be secured up to about 45 degrees, and the horizontal force outputted at the inclination of 45 degrees is converted to the moving speed.

4. As with conventional drones, the type of machine that uses these internal devices, such as shaft or axle, has a low durability. In order to protect the body and to ensure a long life, we have devised a weight car and a rail type protection ring which is an external direction changing device.

5. The flight path of the present invention is relatively irregular if the flight path of the existing flight is relatively regular (meaning that the route of the flight can be predicted at a short moment). In other words, when looking at the helicopter, the trajectory of flight is predicted by the driver's intention to predict the course relatively through manipulation between the adjustments. However, when the direction of the weight carous is determined according to the present invention, the trajectory is considerably irregular. This does not mean that you can not go to destination A, but each path to A is determined by the external environment and the center-of-gravity transformation by the rotation of weight cars.

1. As a means to increase the size and direction of the unmanned drones and to ensure safety, use a rail-type protection ring and weight car as shown in Fig.

2. To prevent the weight car from escaping by centrifugal force or gravity while the rail is in operation, the roller form of the rail and the weight car is physically bent as shown in Figs. 4, 5 and 6

3. Synthesis of weight cars by movement of weight cars The center of gravity of the weight is calculated as follows with reference to FIG. 3 and FIG.

bottom:

Composite weight center point G2 (Lx, Ly)

X axis rotation: Ly = (r * sinA1 + r * sinA2 + rSinA3 + rSinA4) / 4

Y axis rotation: Lx = (r * cos A1 + r * cos A2 + r * cos A3 + r * cos A4) / 4

A2: Angle of weight car w2 with X axis

A3: Angle of weight car w3 with X axis

A4: Angle of weight car w4 with X axis

 r: radius of railtype protect ring

4. Weights of weight cars are all the same

1. The size of the unmanned copter-type drones can be increased in the size of a helicopter in a small toy-level aircraft.

2. It is able to output much faster than the moving speed of existing drone or helicopter.

3. If the conventional drones were to rotate the rotation axis of the blade by a predetermined angle in order to change the direction, the present invention shifts the center of gravity of the weight car to move the slider to secure the horizontal force, Which is one of the external components, without changing the direction of rotation, so that the life time and durability of the base body are increased.

4. In order to make the existing helicopter unmanned, the artificial intelligence computer device should be added while maintaining the present form. However, by using the present invention, it is possible to add the elements of the present invention to the existing helicopter engine and the rotor blade device It can be manufactured, and the same amount of fuel makes it possible to achieve weight reduction, fast moving speed, and wide activity range.

5. The trajectory of the aircraft is made relatively irregular. This means that the probability of being shot down or intercepted by a ground weapon is reduced by military use.

6. The moving speed of the aircraft is fast, and you can operate simultaneously with the ground weapons such as cars and tanks. Even if only the drones of the present invention are used, not the helicopter which is worried about human casualties, joint attack and defense operation of the ground and the air are possible.

7. With the helicopter's engine and rotor blades alone, Bonn drones can be manufactured, so the rest of the weight can carry a relatively large amount of resources such as medical transport, reconnaissance, security, safety, military, and distribution.

1. The change of the traveling direction of the coprecipitated drones on the market requires rotating the dron rotor or the rotor body by a predetermined angle in a direction in which the rotor body is to be moved. It induces secondary machine wear of the shaft or axle supporting the lifting force of the rotor blade or the load of the body drone, thereby reducing the durability of the machine. Moreover, the way to set the direction of rotation of these shafts is limited to increasing the speed of movement of the drones. The reason is that the angle of deflection of the shaft in the forward direction is less than 10 degrees. The horizontal force calculated by turning it by 10 degrees determines the moving speed of the dron body, and at such a small angle, it can not achieve useful speeds industrially and militarily.

 When the vertical lift is secured, the maximum speed is increased by 45 degrees and the horizontal force is increased to the maximum, which is faster than the conventional attack helicopter. The problem is that the existing drones or helicopters have limitations in raising the horizontal movement speed. In order to replace this problem, the present invention has been proposed as a means for securing the direction change, safety, Type protection ring and a weight car. In the present invention, the engine main body, the rotor shaft, and the like are not subjected to any secondary loads, and only the up torque and the body weight load are covered. The system for switching directions is entirely carried out by external weight cars. The dron body tilts according to the position of the center of gravity produced by the weight cars running on the circle, and this property is used to calculate the vertical uplift and horizontal run. The horizontal progressive force is a force that is part of the vertical upward force that occurs naturally because the main body is inclined.

2. The problem should be that the weight car can run steadily on the guard ring rails. The rail structure is designed so that any external impact or force such as centrifugal force can not be detached from the system. In addition, even if the drones are tilted about 45 degrees, the weight car at the bottom can move to the top without any resistance. For this reason, it has been devised to wave the shape of the roller inside the guard ring and the roller inside the weight car. The shape is designed to be bent as shown in Figs. 5 and 6, so that even if a centrifugal force acts, it is not easily detached.

3. Variable center of gravity is always created in the circle by the four weight cars running on the guard ring. The outward direction obtained by connecting the center of gravity G2 generated at that moment and the basic center of gravity G1 of the drone body is the outward direction of the drones, and the relative distance between G1 and G2 determines the slope of the drones. G2 is relative, so you can calculate the exact tilt angle by taking into account the relationship between weight and weights of the basic weight of the drone body. The computer inside the drone can calculate the G2 point, but since the tilt angle of the main body with respect to the distance to G1 is related to the weight of the main body and the weight of the weight cars, in this case, The vertical uplift due to the rotation, and the weight of the weight cars are calculated and input to the computer, so that the accurate tilt angle can be calculated. This process requires the drone himself to calculate the correct horizontal power and travel speed, so that he can fly.

The center of gravity due to the movement of the weight cars is calculated by the following equation and its modification based on the concept as shown in FIG. 3 and FIG. As shown in the mathematical expression, the coordinate G2 of the center of gravity is determined regardless of the weight of the weight cars.

The total center-of-gravity point coordinates G2 (Lx, Ly) by the weight cars are

X axis rotation: Ly = (r * sin? A1 + r * sin? A2 + r * sin A3 +

Y axis rotation: Lx = (r * cosA1 + r * cosA2 + r * cosA3 + ... + r * cosAn) / n

       A1: Angle of weight car w1 with X axis

A2: Angle of weight car w2 with X axis

A3: Angle of weight car w3 with X axis

An: The angle that the nth weight car wn makes with the X axis

 n: the number of WEIGHT CARs

 r: radius of the rail-type protection ring

4. In addition, the drones should be free of tilting of the body when it is positioned at the stop of the air in horizontal position. The absence of inclination of the main body means that the center of gravity G1 of the drone main body coincides with the center of gravity G2 of the weight cars. However, when each weight car has different weights, G1 of the main body and G2 of the weight car do not always coincide with each other at the time of the public stop, and they are tilted. For this reason, the gas naturally tilts and can not stop at a point in the air, and the body rotates while drawing a circle with a certain point in the center at the center. The reason is that the drones of this invention are theoretically moved unconditionally when the body is tilted. Therefore, driving the drones using weight cars of different weights is not an efficient method in terms of technology and resource management. The weight of the weight cars is all the same, so there is little resource to calculate the G2 point or calculate the tilt angle. For this reason, the weights of the weight cars are all equal (within the error range).

On the other hand, even if the weights of the weight cars are unintentionally different within the error range, even if they can be fixed to the air stopping point, this method is not technically perfect and can be regarded as a defective product. Since the computed values of the computer operating with the oscillation of the drones are accumulated in the computed results of the computer, if the operating time of the drones is prolonged, the natural values of the actual phenomena and the computed values of the dron computer are greatly distorted, This can lead to abnormal operation.
