<p>The invention can be used in the construction of aircraft moved by muscular force. Using pedals, the pilot actuates a drive for turning front wheels and a crank mechanism for flapping wing movement. A connecting rod moves downward, the inferior surface of the wing also moves downward. At the same time, the superior and inferior planes of the wing move away from each other and air fills the internal space of the wings through an intake reverse valve. During the subsequent movement of wings, the planes converge and push out the air through outlet valves in the direction opposite to the direction of aircraft movement, creating thereby reactive force. Plates which are mounted on the outer surface of the inferior plane of the wings obstruct a counter air flow, creating thereby an additional lifting force of the wings.</p> |
