Poultry is a simplified version of the flying saucer http://new-original-style.com.ua/pages/a...
The principle of the poultry action is that, by uneven oscillations of the wing, free thermal energy is released from the air in the form of a vortex, which pushes the device. This is contrary to the generally accepted assertions of modern science and is a new discovery. This principle underlies the movement of birds and fish and is more energy efficient than conventional aircraft.  Poultry has a significant advantage, which lies in the simplicity of the design, which in the future will allow to realize greater power without significant mechanical loads, and to create a number of aircraft and spacecraft that correspond to the description of UFO in their characteristics.
