Abstract: A The set of conjugated components to build a ultralight type airplane, in particular a constructive concept that has as end product a ultralight type airplane with a general configuration visually similar to the DEMOISELLE. In summary, the inventive concept has as purpose to enable that a handcrafted and ancient concept airplane is mass-produced, using modern resources, which characterizes by a better aerodynamical sustentation, in particular as a result of parts which are specially designed to carry out the known functions with extraordinarily improved results. In a general concept, without detailing the components in their specific constructions, we define the airplane obtained based on the conjugated components such as the fuselage (1); wings (2); empennages (3); landing gear (4); systems (5) which include the control (6) with rotular ends and fuel systems consisting of a metallic tank (7) fixed on the same level of the engine, with a vent, cover and a system cutting valve and propelling unit (8).
