WING UNFOLDING SCHEME OF LOW-VISIBILITY AIRCRAFT OF SMALL DIMENSION Russian patent published in 2024 - IPC B64C3/56 B64U10/25 

FIELD: aviation.

SUBSTANCE: invention relates to aircraft engineering, particularly, to wings unfolding. Wing unfolding scheme of low-visibility aircraft of small dimension contains fuselage of small-sized aircraft, extension, fixed on side part of fuselage, wing unfolding drive, wing unfolding mechanism, wing unfolding rotary assembly, in-fuselage fixed wing unfolding assembly and wing console. Wing unfolding axis on top and front views relative to aircraft fuselage is located at an acute angle, forming an arched trajectory of unfolding the wing from folded position to unfolded position. At that, in the range from ¼ to ⅓ of the wing console unfolding trajectory, the angle of the transverse V-wing on the frontal projection is formed, which is from 25 to 20 degrees. At that, upper and lower lines of wing console and extension joint are made curvilinear, and lower line of wing console and extension joint is located closer to fuselage in relation to upper line of joint of wing console and extension, forming inclined broken surface of joint of wing console and extension.

EFFECT: reduced dimensions of low-visibility aircraft of small dimension in transport position, provision of lateral stability of small aircraft at separation from carrier, reduced radar visibility of small aircraft after separation from carrier, as well as reduced weight of small aircraft.
