High-voltage electrohydrodynamic (EHD) propulsion system demonstrating ionic wind thrust generation. Features custom-built 30kV+ power supply with voltage multiplier cascade and asymmetric capacitor design.
An ionic lifter (or "lifter") is an electrohydrodynamic (EHD) propulsion device that produces thrust by ionizing air molecules and accelerating the resulting ions in an electric field. This creates a phenomenon known as "ionic wind" or the "Biefeld-Brown effect."
A high-voltage asymmetric capacitor creates a strong electric field. Air molecules near the thin positive electrode (corona wire) become ionized and are accelerated toward the negative electrode (collector), creating momentum transfer and producing measurable thrust.
While not practical for large-scale propulsion, ionic lifters demonstrate fundamental principles of electric propulsion, are useful for physics demonstrations, and have potential applications in micro-UAVs and space propulsion research.
Successfully designed and built a 30kV+ power supply system from 12V input using transformer step-up and Cockcroft-Walton voltage multiplier cascade. Features real-time voltage/current monitoring and safety current limiting.
Demonstrated ionic wind thrust generation through electrohydrodynamic principles. The asymmetric capacitor design produces measurable lift force through momentum transfer from accelerated ions to neutral air molecules.
Implemented proper high-voltage safety protocols including current limiting, proper insulation, safe discharge procedures, and controlled testing environment. Always prioritized safe operation when working with lethal voltages.
This project involves extremely dangerous high voltages (30kV+) that can cause serious injury or death. This documentation is for educational purposes only. Do not attempt to replicate without proper training, safety equipment, and understanding of high-voltage safety protocols. Always work with supervision from qualified professionals when dealing with high-voltage systems.
The sharp corona wire creates an intense electric field that ionizes surrounding air molecules, stripping electrons and creating positive ions near the wire.
Positive ions are accelerated away from the positive wire toward the negative collector grid by the strong electric field gradient.
As ions collide with neutral air molecules, they transfer momentum, creating a directional airflow (ionic wind) that produces thrust on the structure.
