ROTOR (EMBODIMENTS) Russian patent published in 2023 - IPC F01D1/32 

FIELD: mechanical engineering.

SUBSTANCE: proposed rotor is related to a rotor device that converts the energy of a fluid or air flow into mechanical work. In all embodiments, the rotor contains a hub located in the internal space of the casing, which has a complex shape with a narrowing at the end. In the centre of the hub there is a cone-shaped fairing that turns into a shaft mounted in bearing supports. In the first embodiment, on the side surface of the hub there are holes in which the bases of the blades are located, each of which contains an arcuate working surface protruding beyond the hub, forming a channel, while the base of the blade has an annular protrusion and a hole in the shape of a truncated cone with a narrowing to the arcuate working surface of the blade. In the second embodiment, the blades, made integral with the hub, have an arcuate working surface protruding beyond the hub, which on the side surface contains holes in the shape of a truncated cone tapering towards the arcuate working surface of the blade. In all embodiments, the blades on the side surface of the hub are arranged in a checkerboard pattern.

EFFECT: creation of a rotor of a simple design with low labour intensity of repair maintenance, with reliable fixation of the rotor blades on the side surface of the hub.
