Description

[Technical field]

[0001] This invention relates to a drone that is characterized in that, in addition to conventional flight propellers, it is equipped with a feather rotating plate that can diffuse exhaust airflow and, below that, a flight propeller, or a flight propeller and a feather rotating plate, or flight propellers and feather rotating plates are alternately repeated multiple times, thereby increasing the number of propellers and generating more lift. [Background technology]

[0002] Conventionally, drones generally had four propellers for flight, located at the four corners. In addition, all four propellers were arranged in the same horizontal position. Naturally, this was thought to be the most efficient. Nearly 80 years have passed since drones were introduced to the world, but the propellers are still arranged in the same horizontal position for flight. However, in the future, we would like to develop a drone that can carry heavier loads while still being compact. [Prior art documents] [Patent documents]

[0004] [Non-Patent Document 1] Summary of the Invention [Problem to be solved by the invention]

[0005] Conventionally, the flight propellers of drones have been placed in the same horizontal position. These are hereafter referred to as the first-stage flight propellers. Naturally, the force of the exhaust airflow from the first-stage flight propellers is strong, so it was common to not place anything under the flight propellers. Even if a flight propeller is placed under the first stage flight propeller, the propeller will not generate any lift because of the downward force of the exhaust airflow. Hereafter, this propeller placed under the first stage flight propeller is called the second stage flight propeller. Therefore, the exhaust airflow from the first-stage flight propeller is diffused before the second-stage flight propeller is placed. The present invention aims to provide a drone that can obtain a large amount of lift from multiple flight propellers by diffusing the exhaust airflow from the first-stage flight propeller with an arrow feather rotating plate and arranging the second-stage flight propeller below it. [Means for solving the problem]

[0006] The second, third and subsequent flight propellers use feathered rotating plates to generate lift. Effect of the Invention

[0007] Previously, the idea of ​​a second stage had never even occurred to me. By using a fletching rotor, it becomes possible to place a second stage flight propeller and then a second fletching rotor. By repeating this process with a third stage, fourth stage, and so on underneath, any number of flight propellers can be placed. This allows for the creation of drones that can obtain lift from multiple flight propellers and carry heavier loads. For example, a drone that can carry a vacuum cleaner can be created. At construction sites, for example, a drone can be created that can deliver slightly heavy materials to the second or third floor. [Brief description of the drawings]

[0009] Hereinafter, an embodiment of the present invention will be described. First, prepare a device that can diffuse the exhaust airflow so that the second stage flight propeller can be installed on the drone. For example, prepare an arrow-shaped rotating plate, which is a rotating plate attached like an arrow feather to diffuse the exhaust airflow of the flight propeller, as shown in Figure 1 (2). The air intakes can be placed directly under each flight propeller, or a little further away on the bottom of the drone. In short, anywhere that can diffuse the exhaust airflow is fine.

[0010] By placing flight propellers under this fletching rotating plate, a drone with large lift can be created. Flight propellers can be placed in any number of stages, not just the second or third stage. Also, for ease of understanding, we have written stages, but there is no specific location designation, and as long as the fletching rotating plate can diffuse the exhaust airflow, flight propellers can be placed anywhere. As shown in FIG. 5, the flight propellers and the fletching rotating plates may be arranged alternately and repeatedly.

[0011] The number of the fletching plates may be any number, not just one, but two or three, under the flight propeller. Also, the shape and number of the fletching plates are not important, so long as they can be rotated, anything is acceptable. The direction in which the fletching plate rotates can be either. The power used to rotate the fletching plate can be a motor, or if a different technology is developed in the future, it can be rotated by that. It can be linked to the motor of the first stage flight propeller, or a separate motor can be provided. There can be two or three flight propellers under the fletching rotor. The power of the second stage flight propeller can be linked to the motor of the first stage flight propeller, or the motor of the second stage flight propeller can be used to link it to the first and third stages. A separate motor can be provided for each flight propeller, and any motor can be used. The power source used for flight can be a motor, or if a different technology is developed in the future, it can be used to rotate it.

[0012] Although the above-mentioned feather rotating plate is merely one example, it can be achieved infinitely by freely changing the shape, feather shape, plate shape, twisting method, angle, material, length, size, rotation direction, etc., so anything that utilizes the theory of diffusion of the feather rotating plate, regardless of shape, is within the scope of the patent. In addition, the patent also covers the use of a single mechanism, multiple mechanisms, and the combined use of multiple mechanisms. In addition, the feather rotating plate that can diffuse the exhaust airflow of the drone of the present invention may be equipped as a standard feature of the drone, or may be an attached attachment that can be installed later, or it may be a separate product sold separately as an additional mounting part for drones, and is also within the scope of the patent. The present invention has the above-mentioned structure. [Explanation of symbols]
