FIELD: aviation.
SUBSTANCE: invention relates to aircraft engineering, particularly, to structures of multi-screw unmanned aerial vehicles. Multicopter contains electric motors with rotors and rings made of polymer material installed around bearing screws. Said rings of polymer material are fixed between two upper and lower parallel and connected to each other by means of posts plates forming individual protective rings around rotating rotors. Electric motors are installed on support levers of one of plates, and bearing screw does not protrude beyond planes of external surfaces of plates.
EFFECT: ruled out the possibility of the external cutting edge contacting with the propellers with the obstacle in the horizontal flight, reduced probability of the rotors breaking.
