De Seversky noticed an air flow developing between the two electrodes, caused by ionization process previous explained . So I began to develop the idea. The major seemed concerned that the Ionocraft might be mistaken for a kind of space vehicle. It's an airplane, designed to operate within the atmosphere. But it will be able to do things no present type aircraft can accomplish.
Helicopters whirl their blades in utter frustration at altitudes where the air gets thin.
Beyond 20,000 feet, they get almost no lift. Page 3 Unlimited size. The bigger it gets the better it flies. Efficiency increases with grid area. Distributing airflow around the grid edge becomes proportionately less important in larger craft.
