WING WITH VARIABLE AERODYNAMIC CHARACTERISTICS AND AIRCRAFT (VERSIONS)

摘要

FIELD: aviation.;SUBSTANCE: invention relates to aircraft engineering. Aircraft wing with variable aerodynamic characteristics includes main wing profile and additional extended wing shaped elements, which are made in form of rams and / or in the form of extendable under wing. In the extended position the distance between the main wing profile and the ram is not less than 0.5Ci (maximum thickness of the main profile). Said rams extend under main wing profile backward and downward. In the extended position the distance between the main wing profile and the underwing fender is not less than 0.5Ci. When the rams are extended, the lap value between the main wing flap and the ram tail part is Ci. With the extended wing position extended, the lap value between the toe wing tip and the main wing tail is Ci. Value of overlap between tip of second wing rake and tail part of first wing trunk makes Ci. Extendable shaped elements of wing in extended position to change angle of attack can turn about longitudinal axis. Versions of aircraft are characterized by wing shape and location of engines.;EFFECT: group of inventions is aimed at improvement of aerodynamic characteristics of aircraft wing.;3 cl, 95 dwg
