Artificial buoyancy lifting device using coupled electrostatic pistons method and apparatus
View Patent ↗A method of creating aeronautical lift is described which uses a fast voltage electrostatic force to rapidly simultaneously move the top and bottom surfaces of a lifting device downward, followed by a slow voltage electrostatic force to slowly simultaneously return the top and bottom surfaces to their original positions. This cyclic movement reduces downward air pressure on the top surface of the lifting device and increases air pressure on the bottom surface of the lifting device, thus producing aeronautical lift.
1. A method of operating an aeronautical device by simultaneously reducing downward air pressure on a top surface of a lifting device and increasing air pressure on a bottom surface of said lifting device, said method comprising:
simultaneously moving said top surface and said bottom surface of said lifting device downward at a first rate; and
simultaneously moving said top surface and said bottom surface of said lifting device upward at a second rate; wherein said first rate is faster than said second rate;
further comprising:
fabricating said top surface of said lifting device as a top piston;
fabricating said bottom surface of said lifting device as a bottom piston;
fabricating a grounded support plate between said top piston and said bottom piston of said lifting device;
connecting said top piston and said bottom piston of said lifting device together, said connecting to cause said top piston and said bottom piston of said lifting device to move together;
applying a first voltage to said top piston, said first voltage being sufficient to cause a downward electrostatic attraction between said top piston and said grounded support plate;
removing said first voltage from said top piston;
applying a second voltage to said bottom piston, said second voltage being sufficient to cause an upward electrostatic attraction between said bottom piston and said grounded support plate;
removing said second voltage from said bottom piston; and
repeatedly applying and removing said first voltage to said top piston and said second voltage to said bottom piston; wherein the first voltage is different than the second voltage; and
maintaining a vacuum between bottom side of said top piston and said grounded support plate and between top side of said bottom piston and said grounded support plate.
2. The method as in claim 1 further comprising: fabricating said top piston and said bottom piston from titanium.
3. The method as in claim 1 further comprising:
fabricating a plurality of ribs on top side of said top piston and on bottom side of said bottom piston, said ribs designed to stiffen said top piston and said bottom piston.
4. The method as in claim 1 additionally comprising: mounting one or more said lifting devices on an object to be lifted, wherein said top surface of said plurality of said lifting devices are pointing in direction of desired said aeronautical lift.
5. The method as in claim 1 additionally comprising: placing said lifting device in a sealed enclosure;
filling said sealed enclosure with a gas; and
maintaining said gas in said sealed enclosure at a constant specified pressure.
6. The method as in claim 5 additionally comprising:
maintaining said gas in said sealed enclosure at a constant specified temperature.
7. The method as in claim 5 additionally comprising:
selecting said gas in said sealed enclosure whose molar mass is higher than molar mass of standard atmosphere air.
8. The method as in claim 5 additionally comprising:
selecting said gas in said sealed enclosure to be sulfur hexafluoride (SF6).
9. The method as in claim 8 additionally comprising:
mounting a power supply in said sealed enclosure.
10. The method as in claim 1 further comprising:
mounting a plurality of upward pointing Double Post Capacitive Micromachined Ultrasonic Transducer (DPCMUT) cells on said top surface of said lifting device; and
mounting a plurality of downward pointing DPCMUT cells on said bottom surface of said lifting device.
11. The method as in claim 10 additionally comprising:
placing said lifting device in a sealed enclosure;
filling said sealed enclosure with a gas; and
maintaining said gas in said sealed enclosure at a constant specified pressure.
12. The method as in claim 11 additionally comprising:
maintaining said gas in said sealed enclosure at a constant specified temperature.
13. The method as in claim 11 additionally comprising:
selecting said gas in said sealed enclosure whose molar mass is higher than molar mass of standard atmosphere air.
14. The method as in claim 11 additionally comprising:
selecting said gas in said sealed enclosure to be sulfur hexafluoride (SF6).
15. The method as in claim 10 additionally comprising: mounting said lifting device inside an enclosure, said enclosure designed to be worn by an individual; pointing said top surface of said lifting devices in a first direction; providing a control for said individual to set a desired lift force; and adjusting said lifting device to a desired lift force.
16. The method as in claim 15 wherein said enclosure is selected from the group consisting of: a vest, life preserver, coat, or jacket.
17. The method as in claim 1 further comprising:
fabricating lifting device pistons via 3D printing.
