SWEPT WINGS ATTACHMENT STRUCTURE WITH FUSELAGE OF AIRCRAFT-TYPE UNMANNED AERIAL VEHICLE

摘要

FIELD: unmanned aerial vehicles.;SUBSTANCE: invention relates to the design components of aircraft-type drones. Design of sweep of wings with fuselage of an unmanned aerial vehicle of aircraft type consists of a rod which is inserted into a guide located in the fuselage and perpendicular to its longitudinal axis and of external fixing connection. Rods are made rectangular from carbon fibre. Guide is made in the form of a taper metal collapsible sleeve consisting of two equal longitudinal parts with holes for screw fastening. In each part there are slots, geometrical dimensions of each are equal to half of geometrical sizes of rod. Guide sleeves are installed coaxially in fuselage and in sweep wing. Guiding shell in the fuselage has rigid fixation with a spar perpendicular to the longitudinal axis of the device. Guide sleeve in sweep wing has rigid attachment with plastic wedge-like substrate, which has rigid attachment with plywood sweep wing. Wedge angle relative to longitudinal axis of the front plywood spar apparatus makes 14.2°, and wedge angle for rear plywood spar is 11.5°. External fixing connection is made in form of metal platform with hole for screw attachment, rigidly fixed on fuselage, and an aluminium eye with a hole for screw attachment, rigidly fixed on the wing, which are connected to each other by means of a polyethylene screw.;EFFECT: invention is aimed at preservation of swept wing integrity against destruction at standard landing of an aircraft-type unmanned aircraft.;1 cl, 4 dwg
