AI Technical Summary
Existing propulsion methods, such as rocket propulsion and propeller-based systems, are inefficient in energy consumption and pose safety risks, and there is a lack of effective means to directly convert centrifugal force into continuous thrust.
A thrust generating device utilizing spheres within a spiral-shaped hose, rotated by an outer-rotor brushless motor, creates an imbalance in centrifugal force to generate continuous thrust by controlling rotational speed.
Efficient conversion of centrifugal force into thrust enables extended flight range and safe operation for various flying objects, including satellites and spacecraft, using energy sources like solar cells and nuclear batteries.

Abstract
Description
Technical Field
[10001] This invention is based on the operating principle of an outer-rotor brushless motor, and utilizes the imbalance of centrifugal force generated in the balls built into the structure to generate a thrust force in a certain direction of the structure.
Background Art
[10002] Currently, as an example of the method of moving a flying object in space, rocket propulsion and ion jet propulsion are utilized. As an example of attitude control, thrusters and flywheels are utilized. Also, for moving methods and attitude control on the ground and in the air, as technologies typified by VTOL aircraft, helicopters, and drones, thrust is obtained from turbojet propulsion or propellers and utilized.

Summary of the Invention
Problems to be Solved by the Invention
[10005] In the prior art, a large amount of fuel and energy were consumed for rocket propulsion when moving on the ground or in space. Also, in the case of propulsion by propellers typified by helicopters, drones, and ships on water, since the blade rotator rotates at high speed, dangerous situations are likely to occur in the surroundings during operation, and it can only be operated in a space where fluids such as air and water are present in the space. Currently, there are researchers and engineers who are conducting experiments and verification on cases of directly converting centrifugal force into thrust. All of them have a pulsating mechanism that utilizes the inertial force of linear reciprocating motion or a pulsating mechanism that utilizes the eccentricity of the centrifugal force acting on a rotating body, and they have not yet achieved efficient and continuous conversion of centrifugal force into thrust. Based on such cases, a newly devised thrust generating device is provided.
Means for Solving the Problem
[10006] The present invention arranges spheres in the hollow part of a hose having a spiral structure in a part of its shape, and continuously rotates the spheres inside the hose by an electromagnet arranged on the outer peripheral side of the hose. In the overlapping part of the spiral shape of the hose structure, an imbalance is caused in the centrifugal force acting on the spheres, and the rotation of the spheres is controlled in terms of rotational speed by the electromagnet so that the whole structure moves in a certain direction, thereby continuously generating and controlling thrust.
Effect of the Invention
[10007] Conventional thrust generation by rocket propulsion requires a large amount of energy resources. There are limitations to the amount that can be built into the aircraft, and there are problems such as fuel refilling and flight range. Also, although the gyroscopic effect can be used to control the attitude of artificial satellites in space by using the rotational force of an electric motor, and attitude control of the XYZ axes can be performed by a flywheel, there has been no prior art that can efficiently convert the centrifugal force derived from the electric rotational force directly into thrust. With the present invention, by being able to efficiently convert directly from the centrifugal force derived from the electric rotational force into thrust, it is expected that it can be used as a thrust and attitude control device for all flying objects such as artificial satellites, outer space exploration vehicles, and interstellar spacecraft, both on the ground and in space, while utilizing solar cells, nuclear batteries, etc. In addition, it is expected to extend the flight distance.

Modes for Carrying Out the Invention
[10009] The structure of the present invention has as its basic structure extracting the centrifugal force generated in the vectors on the circumference to the outside of the system. Therefore, in propeller propulsion typified by a drone, thrust is generated in the direction perpendicular to the axis in the direction of the blade rotation circumferential surface, but for example, if it is replaced with the propellers of a 4-rotor drone, the structure of the present invention will be at an attachment position rotated 90 degrees with respect to the circumferential direction of the propeller. This is because when the rotor blades of the drone rotate, when viewed from the side of the drone body, they rotate in a horizontal circumference, whereas the structure of the present invention utilizes the centrifugal force of an object rotated in the vertical circumferential direction as thrust. In any case, by finely controlling the rotational force of each individual thrust generation device arranged on each leg, the aircraft can take off, land, control its attitude, and move in space.

By a <6> electromagnet, based on the operating principle of an outer-rotor type brushless motor, the balls <1>, <2>, and <3> inside the <5> hose are rotated at high speed within the <5> hose. In the overlapping portion <7> of the spiral shape, an imbalance is caused in the centrifugal force applied to the balls <1>, <2>, and <3>, and the rotation of the balls is controlled by the <6> electromagnet so that the entire structure including the spiral <5> hose advances in a certain direction, thereby continuously generating thrust.
