Gas propulsion thrust device

A gas propulsion thrust device comprising:

• a cone-shaped propulsion element having a rigid concave first side, the concave first side extends to an outer edge and is axisymmetric about a longitudinal axis aligned along the direction of propulsion thrust, the propulsion element having a convex second side adjacent to the concave first side, the propulsion element is submerged in and surrounded by gas, the propulsion element is equipped with a plurality of electromagnetic coils,
• a magnetic levitation high-frequency linear actuator aligned along a direction of propulsion thrust, the high-frequency linear actuator operates at a frequency from 500 Hz to 200 kHz and comprises a plurality of permanent magnets operatively cooperating with the plurality of electromagnetic coils of the propulsion element to form a plurality of electromagnets, the electromagnetic coils configured to control position and cause reciprocal motion of the propulsion element along the direction of propulsion thrust, wherein the magnetic levitation high-frequency linear actuator comprises a plurality of linear actuators positioned symmetrically around and individually spaced along the outer edge of the propulsion element,
• a thrust chamber supporting the high-frequency actuator fixedly attached thereto, the thrust chamber surrounds the propulsion element while being spaced away from the outer edge thereof by a gap configured to direct gas from the second side to the first side of the propulsion element, wherein the thrust chamber is shaped to maintain the same gap throughout a reciprocal motion of the propulsion element within the thrust chamber, the thrust chamber is shaped to narrow and taper around the propulsion element at the second side thereof, and
• a gas directing cone-shaped cap mounted on the thrust chamber adjacent and outside the second side of the propulsion element, the gas directing cone-shaped cap is configured to direct gas around a periphery thereof and further around the second side and toward the first side of the propulsion element,
• wherein the thrust chamber and the gas directing cone-shaped cap are submerged in and surrounded by the gas surrounding the cone-shaped propulsion element,
• wherein the reciprocal motion of the propulsion element within the thrust chamber is done without altering the shape of the propulsion element, and
• wherein the reciprocal motion of the propulsion element forms a high gas pressure zone on the concave first side of the propulsion element and a low gas pressure zone on the convex second side thereof, thereby generating a gas pressure differential across the propulsion element and along the direction of propulsion thrust causing propulsion of gas away from the concave first side of the propulsion element and in a direction opposite the direction of propulsion thrust.
