UNMANNED AERIAL VEHICLE OF VERTICAL TAKE-OFF AND LANDING AND METHOD OF MANUFACTURING THEREOF Russian patent published in 2024 - IPC B64U10/20 B64C29/00 

FIELD: aviation.

SUBSTANCE: invention relates to aircraft engineering, particularly, to drones with vertical take-off and landing. VTOL drone comprises fuselage with fixed wing and tail unit, lifting and cruising rotor groups equipped with electric motors and landing gear. Fuselage consists of longitudinal upper and lower beams, frames, side panels, front and rear hatch covers, nose cone and its cover, spring attachment, under-fuselage pylon of payload attachment, tail cone and its cover. Wing consists of three lower panels and three upper panels, interconnected by bushings, embedded bushings, pins and ties, wherein the lower panels are equipped with underwing pylons for attachment of the payload, two flaps of the centre section, two flaps of consoles, two ailerons connected to the panels by means of hinges, two end fairings; tail unit consists of stabilizer panels, stabilizer embedded bushings, elevator spar, elevator attachment bracket, hatch covers of stabilizer panels, left and right keel panels connected to stabilizer by means of mounting bushings, hatch covers of keel panels, rudders, rudder spars and rudder hinge assemblies. Lifting propeller groups consist of two engine nacelles of lifting engines installed on lower surface of two extreme lower panels of wing in their middle part, by means of mounting screws, pylons of lifting engines and tail lifting engine installed in rear part of fuselage under hood of tail engine on tail support, which is attached to upper longitudinal beams, besides, tail lift engine is equipped with rudder of lifting direction and spar. Cruise propeller groups in form of two engine nacelles with hinged covers, propellers of propellers, propellers with folding blades are installed on middle section of wing by means of mounting screws and pylons and are equidistant from fuselage centre. Landing gear is made in form of two landing supports with fairings, equipped with wheels in wheel fairings, attached to fuselage by means of front struts and springs; in addition, parts of fuselage, wing, its steering surfaces, tail unit, landing gear, parts of power plants of lifting engines are made from engineering plastic by injection moulding; polyamide ZEDEX-066 GF30 can be used as engineering plastic. Receiving device is installed inside fuselage to receive and transmit command to cruise engines for take-off and landing from control panel. Group of inventions also relates to a method of making such an unmanned aerial vehicle.

EFFECT: reduced cost of UAV due to improvement of technical process of parts manufacturing and reducing the cost of the UAV by making parts from engineering plastic by injection moulding on a thermoplastic machine and connecting the parts to each other by vibration welding.
