FIELD

The present disclosure relates generally to a flying device. More specifically, the present disclosure relates to a flying device that converts the rotation of a liquid into a lifting force.

BACKGROUND

An engine is a machine designed to convert energy into useful mechanical motion. An engine burns or otherwise consumes fuel and is different from an electric machine such as an electric motor that derives power without changing the composition of matter. Various types of engines exist today and may be powered by electricity, steam, solar, turbine, rotary and piston type. An engine powered by a lifting force that provides mechanical motion to a mode of transportation, such as a flying device, is needed.
An electric mixer can be used to demonstrate the lifting force used to mobilize a flying device. When a liquid such as water is placed into a covered mixer and such mixer is activated, the rotated liquid moves to the outermost edges of the mixer away from its center. The rotated liquid also gravitates up the outermost edges of the mixer. The mixer typically has a somewhat if not completely spherical shape or spherical sector. The combination of the spherical shape and rotation creates a lifting force that lifts the cover of the mixer up and away. Such lifting force is based on the law of centrifugal force which states F=mV²/r where F is force, m is mass, V is velocity and r is radius of rotation. Lifting force created by the rotation of a liquid may be used to elevate a flying device.

DETAILED DESCRIPTION

Referring to FIGS. 1-2, various embodiments of the present invention comprise a flying device 1 which may be the shape of a disc sliced from the top of a sphere. Flying device 1 comprises a lower portion 4 and an upper portion 6. In FIGS. 1-4, the height of device 1 is represented by 42. In one embodiment, lower portion 4 has a height equal to two sevenths of the total height 42 of device 1. Upper portion 6 has a height equal to five sevenths of the total height 42 of device 1. Device 1 has a radius represented by 44 and a base circular center point 40. Such dimensions of an exemplary embodiment allow device 1 to produce a large static sphere that protects and shields device 1 and also serve as a pushing force. The weight of flying device 1 may vary as desired by one skilled in the art. The heavier the flying device 1, the greater the lifting force and greater the electrostatic shield. In one embodiment, at the base circular center point 40, (best shown in FIG. 1) the height of upper portion 6 is less than the radius of the base of lower portion 4 in a ratio of 7 to 15.
In one embodiment, flying device 1 comprises a partially hollow circular disc filled in part with a liquid 14 in the lower portion 4 of the circular disc.
Referring to FIGS. 2-4, in one embodiment, upper portion 6 comprises a top and a bottom with a central cylindrical hole 25 which extends from the top of the upper portion 6 to the bottom of the upper portion 6. In another exemplary embodiment, lower portion 4 comprises a tank 8 configured to hold a liquid 14. In one embodiment, the device 1 has a propeller 12 disposed in lower portion 4 and a motor 10 mechanically connected to propeller 12.
In a further embodiment, shown in FIGS. 5-12, lower portion 4 has a hollow rim 50 (best shown in FIG. 8) forming a recessed portion 52 configured to receive the upper portion 6. In one embodiment, device 1 comprises a base cover 54 (best shown in FIG. 9) attached to the lower portion 4.
In one embodiment, flying device 1 may be made of steel but any other metal or strong material may be used as desired by one of skill in the art. In one embodiment, the inside of upper portion 6 may be lined with glass while the outside of upper portion 6 may be lined with zinc which allows flying device 1 to charge itself once air borne. The glass lining allows a charge to be gathered on the outside shell of flying device 1. As desired by one of skill in the art, any other material, such as silicone or plastic, may be used to line the inside of upper portion 6 as long as such material will allow flying device 1 to charge itself once airborne.
In one embodiment, flying device 1 has one electric motor 10 mechanically connected to propeller 12. Electric motor 10 is located at the center of device 1 and may be attached to upper portion 6. In one embodiment, motor 10 is powered by direct current voltage provided by batteries. Device 1 may also be powered by an electric generator as shown in FIGS. 13 and 14.
In another embodiment, flying device 1 may have more than one motor 10, such as two, three or four, as long as flying device 1 is balanced despite using such plurality of motors. Motor 10 may be mounted above the base circular center point 40 of upper portion 6 allowing propeller 12 to rotate inside lower portion 4 when motor 10 is activated. In another embodiment, the height of electric motor 10 and propeller 12 may be less than the height of upper portion 6 which will allow the center of weight or weight center of flying device 1 to be above motor 10. The weight center may be outside the physical body of flying device 1 yet within the cylindrical hole located in the center of upper portion 6 and on the vertical line above the base circular center point 40 of lower portion 4.
Referring to FIG. 2, in one embodiment, flying device 1 contains no liquid in tank 8 making upper portion 6 heavier than lower portion 4 making the weight center of flying device 1 at A. Referring to FIG. 3, in one embodiment, tank 8 contains liquid 14 such as salt water which causes lower portion 6 to increase in weight leading to a change in the weight center of flying device 1. The weight center in FIG. 3 is represented by B. Referring now to FIG. C, tank 8 contains liquid 14 such as salt water and motor 10 is activated resulting in the rotation of propeller 12. Liquid 14 in lower portion 4 is forced by rotating propeller 12 to the outside edges of lower portion 4 of flying device 1 leading to a change in the weight center of the flying device, wherein the weight center is represented by C. A lifting force D represented by F=mV²/r is created when liquid 14 is applied to the curved outside edges of lower portion 4 of flying device 1 enabling flying device 1 to elevate. Weight centers A, B, and C are along the same center line which is located at a right angle to flying device 1 base circular center point 40. In one embodiment, upper portion 6 is heavier than lower portion 4.
When motor 10 of flying device 1 is activated, a lifting force represented by D, as seen in FIGS. 4 and 12, is created. The lifting force is based on the law of centrifugal force which states F=mV²/r where F is force, m is spinning mass of device 1 and liquid 14, V is spinning velocity and r is radius of rotation. Once motor 10 is activated, the majority of the mass of the liquid such as salt water will be located on the outermost curved edges of device 1 thus allowing the lifting force to be applied to edges of the lower portion 4 of device 1. Such lifting force is represented by D in FIGS. 4 and 12. The rotating salt water will cause flying device 1 to rotate. The rotations of the water and device 1 combine to create the spinning velocity. A greater spinning velocity results in a greater lifting force applied to the edges of lower portion 4 of device 1. There is an unlimited speed (or velocity) of rotation due to the combined spinning of device 1 (caused by the rotation of the propeller) and the spinning of motor 10 in the same direction. Motor 10 is attached to upper portion 6 making the upper portion 6 heavier than the rotating water in lower portion 4 thus preventing any reverse rotation of device 1. Flying device 1 will elevate as soon as a positive value of force is generated.
In one embodiment, shown in FIGS. 11 and 12, tank 8 comprises liquid 14, such as, but not limited to, salt water or sea water. The volume of liquid 14 used in tank 8 depends on the weight of upper portion 6. In one embodiment, tank 8 is filled with salt water up to one third of the total weight of flying device 1. The volume of liquid 14 may not exceed two thirds of the total volume of tank 8. Salt water will negatively charge flying device 1 once activated creating a shield surrounding flying device 1. The salt water ions gather on the outside shell of flying device 1 due to Faraday's law which states that electrostatic charges gather on the outside of the device 1 due to the repelling force between the same charges. The electrostatic shield reduces the refraction between flying device 1 and the air allowing the device to travel more smoothly. The electrostatic shield also protects flying device 1 from heat. Additionally, once flying device 1 is fully charged, the electrostatic shield allows the device to be invisible to radar. Lifting force and rate of rotation are positively related. The faster the rate of rotation the greater the lifting force.
Referring to FIG. 13, in one embodiment, zinc plates 20 are attached to the inside of upper portion 6. The positively charged zinc plates 20 reflect the salt water and also function as water breakers to break the speed of the rotating water. Zinc plates 20 reduce the rotating speed of the water allowing flying device 1 to increase speed gradually.
Referring now to FIGS. 13 and 14, in one exemplary embodiment, upper portion 6 comprises a steering device. Steering device comprises a plurality of motors 15 attached to a plurality of rods 18 and a plurality of weights 16. In one embodiment, there are four motors 14, four rods 18 and four weights 16. Each motor 15 controls one rod 18 which moves one weight 16 back and forth on the threaded rod 18. In one embodiment, motors 15 are servo DC motors but any motor may be used as desired by one of skill in the art. Each weight 16 may travel back and forth perpendicularly to the motor 15 on the threads of its respective rod 18. The movement of one or more weight 16 at any one time causes uneven distribution of weight 16 allowing device 1 to move in different directions.
Referring now to FIGS. 13 and 14, in one embodiment, device 1 comprises an electric generator which may generate power from the rotation of device 1. Such power created by the generator may be used to recharge batteries 30 which may allow motor 10 to remain activated. Generator has cylinder with magnets 28 and coils 26. Bearings may be used to secure generator to upper portion 6 of device 1.
Referring now to FIG. 13, in one embodiment, motor 10 may be supported by a plurality of posts 32. Posts 32 may be made of steel or any other material as desired by one of skill in the art. In one embodiment, posts 32 support the weight of upper portion 6 and/or motor 10.
Experimental Data. In one embodiment, device 1 was designed by a fixed height to radius ratio of 7:22. The height is measured from the center of device 1. The radius is the radius of the lower portion 4. Device 1 is built to have a radius of 22 centimeters and a height of 7 centimeters. Tank 8 has a height of 2 centimeters. Seawater with a density of 1.035 gm/cm³is used. The total amount of liquid that will be used will be equal to the area of the base of the lower portion multiplied by the height of the lower portion.
