WebAbstract—Ionic winds are air flows that are generated when ions driven by an electric field collide with air molecules. This collision transfers momentum from the ion to the air mole-cule, thus generating a bulk flow. Typically, ionic winds are generated by gas discharges requiring large input voltages (>5 kV) applied between two electrodes. Web30 nov. 2024 · A plane powered by ionic wind takes flight. Revisiting Discarded Research.

WebAn ionic or electric wind is a bulk air movement induced by electrohydrodynamic (EHD) phenomena in a gas discharge. Because they are silent, low power, respond rapidly, and require no moving parts, ionic wind devices have been proposed for a wide range of applications, ranging from convection cooling and food drying to combustion management. WebStep 1: What in the Science Is Going On. Electrostatic wind goes by many names. Ionic wind, electric wind, or my usually favorite corona wind. The main driving force behind this concept is a high voltage source and an air gap between that source and ground. Another term for voltage is potential difference.
