FLYING VEHICLE Russian patent published in 1997 - IPC

FIELD: aeronautical engineering; manufacture of superlight flying vehicles, for example, flying vehicles without power plants. SUBSTANCE: flying vehicle includes fuselage 1 made in form of tube with central vertical strut also made in form of tube of similar diameter as compared with tube of fuselage 1 and tubular spar 5 of wing 6. Each panel of wing 6 is articulated by its spar on strut 2 on hinge. Vertical mast 8 is mounted on strut 2 on longitudinally oriented hinge. Mast 8 has varying length for locking the mast in required position. V-shaped wire 10 is secured at two points on tube of fuselage 1 and at point of securing the wires on tubular spar of wing 6 lying within 0.3-0.4 of its semispan. Wire 11 connects upper point of mast 8 and. point of securing wires 10 and 11 on spar 5 which lies within 0.3-0.4 of semispan of wing 6. EFFECT: reduction of drag, enhanced rigidity of construction, facilitated assembly and disassembly, reduction of impact loads at landing and unification of construction. 12 cl, 13 dwg
