AERODYNAMIC DEVICE WITH HINGED FLAP (VERSIONS) AND METHOD OF DEPLOYING HINGED FLAP Russian patent published in 2017 - IPC B64C3/46 B64C9/16 

FIELD: aircraft engineering.

SUBSTANCE: group of inventions relates to aircraft engineering. Aerodynamic device with a hinged flap comprises a part with aerodynamic profile, a deployable flap able to move between the non-activated state, the first configuration and the second configuration, and a system of inflatable chambers containing the first and the second compartments made with the possibility of individual inflation and placed adjacent to each other. First and second compartments are located between the flap part and the top surface, when the flap is in the non-activated state. In another version the aerodynamic device with a hinged flap comprises a part with aerodynamic profile having a recess and a back edge, a deployable flap able to move between the storage position and the deployed position, an inflatable chamber, segments of which are located along the wing span. Method of deploying the hinged flap includes supply of compressed air to the first and the second compartments of the inflatable chambers system placed adjacent to each other and between the top surface of the part with aerodynamic profile and the hinged flap section located along the wing span.

EFFECT: group of inventions is aimed at elimination of additional resistance.
