Goal
Generate lift and horizontal thrust using shaped electrostatic fields and ion streams without conventional engines.
Problem
Provide a propulsion method that creates thrust through electrostatic pressure and ion repulsion, eliminating the need for moving mechanical parts.
Concept Summary
The design uses a conical arrangement of electrodes to shape electric fields, creating hydrostatic pressure and transverse ion repulsion. Positive ions are emitted from a side-mounted source and are repelled outward by electrons and negative ions, producing a net upward and horizontal thrust. The anode and cathode geometry is tuned to maximize field-shaping and pressure distribution, allowing lift in atmosphere and increased pressure when approaching a surface.
