Abstract: A hybrid multirotor propulsion system for an aircraft includes a plurality of propulsion units, each propulsion unit having a propeller, an electromotor and a peripheral differential gearbox; a plurality of driving elements, each of which is coupled to a respective one of the plurality of propulsion units; a mechanical power source; a main distributor gearbox; at least one electric machine; and a power management unit. The power management unit is configured according to a predetermined operating mode, which causes the mechanical power source to output first and second mechanical power components; and distributing the first mechanical power component to provide each driving element with a direct mechanical propeller power; and causes the electric machine to convert the second mechanical power component into electric power, part of which provides each electromotor with an electric propeller power.

Abstract: The self-folding pizza packaging box with the compartments and carry handle belongs to the area of transport packaging. The box (1) is made of the folded blank (A), formed by folding and gluing into a flat form of the box (1), and is formed from the upright surfaces in a vertical position. The box (1) is made in the form of a prism with bases (2, 3), parallel lateral panels (4, 4??), while its other two parallel sides are rectangular flaps (5). The box (1) is formed by folding upwards the lateral panels (4, 4?) of the rectangular shape along the folding lines (2.1, 2.2, 3.1, 3.2), by straightening the flaps (9.1, 9.2, 9.3, 9.4) which are continued to the lateral panels (4, 4?) and by folding upwards the rectangular parts of the flaps (5) along the folding lines (2.3) so that it is brought to a vertical position to the bases (2, 3) of the rhomboid shape.

Abstract: A self folding polygonal impermeable food box and a tool for its forming. The box is made from cardboard coated on its inside with PET film or foil. The box has a bottom, six lateral sides, two lateral sides and eight corner sides which are partially transparent and directed towards the inside of the box. The box is covered by a cover so that the sides of the cover rest on the outer surfaces of the lateral sides and seal the box. There is also a second variant of the box. The tool for forming the box, which is preferably made from stainless steel, has a bottom, six guides and two guides, which form the six lateral sides and the two lateral sides of the box.

Abstract: A self folding box with a carrier for packing of pizza, as well as a tool for forming the box, comprises a box (A) with a lower part (1) of the box and a cover (2) of the box, wherein on a bottom (1.1) of the lower part (1) of the box is placed a carrier (4) for two slices of pizza quarter. Lateral sides (1.2, 2.2), auxiliary sides (1.8, 2.8) and an opposite side (1.5, 2.5) are made around bottom (1.1, 2.1) both of the lower part (1) and the cover (2) of the box (A). The lateral sides (1.1, 2.1) and the auxiliary sides (1.8, 2.8) are mutually connected and locked by means of tongues (1.3) entering slots (1.10). The opposite side (1.5, 2.5) is locked in a slot (1.7) in the bottom (1.1, 2.1) by means of a tongue (1.6). The carrier (4) comprises two pads (3) for one slice of pizza quarter, which are superposed one on another, so that the tongues (3.3, 3.4, 3.6) of the sides (3.2) of the upped pad (3) enclose from outside the sides (3.2) of the lower pad (3), while the trapezoidal tongues (3.
