FIELD: aircraft engineering.
SUBSTANCE: folding airfoil comprises centre section and panel articulated therewith at centre section coaxially with folding axis and allow the contact between pusher and screw rod. Said rod is fitted in two aligned cylindrical bores, one being located at centre section and provided with screw grooves for screw rod ledges to fit in while another bore is made in aforesaid panel. Said rod and panel bore make a sliding slotted joint. Rod slotted joint side end has threaded bore aligned with rod axis while centre section wall on side of said end has bore for access to threaded bore. Centre section has height-adjustable ledge for panel thrust at turn through opening angle.
EFFECT: perfected aerodynamics, optimum application of the drive.
