Abstract:

The flexible wing in the 1970s gained great popularity for aviation sportsmen. Then inventors installed a motor on the delta glider, extending the happiness of flight, in terms of feeling. Close to that of a bird. The further development of such variants led to the creation of a more improved flying vehicle - ultralight, that is, an aircraft of a schematic tubular construction with a soft covering. Having preserved the main constructive principles of the delta glider, including the simplicity of assembly and disassembly, compactness in the collapsed form, the ULA acquired a higher aerodynamic efficiency. It became simpler in control, safer and, to a certain degree, more comfortable. Such vehicles have recently become wide spread. This paper describes an ultralight aircraft called the Antis. Using the carrying properties of the horizontal tail - the front wings, the inventors of the Antis reduced the size of the main and entire vehicle on the whole which showed up in an improvement of the flight characteristics. For the assurance of good directional stability the vertical tail - large control surface for turning was placed by the inventors behind on the separated frame. They did not use a traditional aileron, having been used for control in roll a twisting of the wings, like in aircraft at the start of the century. The vehicle turned out to be externally reminiscent of the antique flying vehicles of the Wright brothers era. Keywords Russian translators.
