ADAPTIVE WING WITH FLEXIBLE GAPLESS MECHANIZATION Russian patent published in 2022 - IPC B64C3/48 

FIELD: aircraft industry.

SUBSTANCE: invention relates to the field of aircraft (aircraft, cruise and feathered missiles, helicopters), in particular the adaptive elements of their designs. Adaptive wing with flexible gapless mechanization contains a central caisson, rigid rotary links of the frames of the nose and tail sections of the wing and the elastomeric panels associated with them, forming, together with the frame and pre-tensioned elastic film or tensile fabric and the caisson, smoothly changing contours of the aerodynamic surface of the wing. Each of the rotary links of the frame of the bow and tail of the wing consists of stringers rigid for bending and torsion with a height equal to the local thickness of the profile, based on hinged, deflectable sections of rigid curvilinear power ribs of variable geometry, while the axes of rotation adjacent to each other are hinged deflected sections of the power ribs are oriented parallel to the direction along the span of the corresponding support stringers of the adjacent link, on which the pivot nodes of the links are fixed. Between the support stringers of neighboring links there are elastomeric panels consisting of SDS cells filled with elastomeric filler, the central elements of which are oriented normal to the axis of rotation of their link and are momentarily connected to the support stringers of neighboring links, forming a single curvilinear chain of SDS cells, in which the end of one SDS cell coincides with the beginning of another. The planes of all elements of SDS-cells: central, supporting and peripheral are oriented normally to the middle surface of the flexible gapless mechanization. SDS cells have different heights both along the chord and along the span of the wing, thereby reproducing, together with the elastomeric filler, the aerodynamic profile of the wing in the area of flexible gapless mechanization, underestimated by the thickness of the elastic film or tensile fabric stretched over the frame.

EFFECT: adaptive wing with flexible gapless mechanization creation.
