Abstract

The invention is related to the field of aircraft specifically to unmanned drones with multiple propellers and protection against external influences. Disc-shaped multi-propeller aircraft with a protective frame (1) consists of outer (2) and inner (3) rings interconnected by spokes (4) and openwork lids (11, 12) covering areas between outer (2) and inner (3) rings, the spokes (4) being arranged in two levels, the drive units - motors (5) with impellers (6) mounted on the spokes (4) and arranged in two levels in the area between the outer (2) and inner (3) rings so that counting them in sequence – the odd above and the even below, or vice versa, the adjacent impellers (6) overlap each other, the inner ring (3) is made hollow by its outer walls interconnected by thin-walled partitions, the control (8) communication nodes (9) and the batteries (7), and the central opening (10).

Abstract

The invention is related to the field of air vehicles, in particular to unmanned drones with multiple propellers. The folding drone consists of two housings (1, 2), with motors (5, 6) and impellers (7, 8) mounted thereon, which are interconnected by two parallel levers (3, 4). The levers (3, 4) are connected to the housings (1, 2) by flat hinges (9, 10). The transfer of the drone from the working position to the transport/storage position can be done by manually pulling one housing (1) from one another (2) to the positions of the fixed levers (3, 4) and vice versa by pushing the housings (1, 2) one to another till the smooth contact. Other known mechanical positioning methods or servo drive may be used. The levers (3, 4) and hinges (9, 10) are hollow which the wires connecting the drone electronic assemblies pass through.
