Researchers from the Massachusetts Institute of Technology performed the first airplane model monolete, which uses the phenomenon of jonvind, called the effect of Biffeld brown. It is reported N + 1.
During the tests, the airplane is flying about 60 meters at an altitude of 47 inches from the floor. The launch of the aircraft was performed using the catapult.
The phenomenon of ion gain is characterized by the formation of a stream of ionized air between two separated electrodes to which a high voltage of tens of kilovolts is applied. 1
9659004] Some researchers have suggested advanced design of aircraft that would use the jonvind phenomenon, but the projects were closed. It is believed that the engines that use the effect of Biffeldbrun can not provide good traction.
In reality, some experimental aircraft were called lifters or monoliths. They represent the light body in the form of a polygon, usually a triangle, which is an electrode in the form of copper wire and foil tape. Such devices can climb vertically, but completely unmatched.
Model flight monolith made according to the schedule. Under the outer wing panels, the researchers found four horizontal electrodes, which occur in the ion wind phenomenon. According to researchers, the engine in this construction gives a drag of three of Newton (about 306 grams of power). The power of the power plant is 500 watts. The aircraft has a wing stress of five meters and a mass of 2.45 kg.
The aircraft got the battery Mounting of lithium polymer batteries that can supply voltage from 160 to 225 volts.
