SUBWAY POWER PLANT ON AIR FLOW Russian patent published in 2018 - IPC F03D3/06 F03D9/46 

FIELD: engines and pumps.

SUBSTANCE: invention relates to the field of subway power stations on an air flow. Rotor with blades on the oncoming air flows from the electric train traffic, installed between the counter metro tunnels, contains a vertical shaft. To the shaft are rigidly attached parallel to each other the upper and lower disks, fastened to each other by pins, with the blades made of fiberglass placed between them, that made concave along a curvilinear profile and attached on one side to the pins, and on the other hand - fixed to each other, while on the upper surface of the upper disc wings are rigidly fixed, equally spaced along the circumference, having gaps between the wings and the upper surface of the upper disc, the rotor shaft in the lower and upper parts has half couplings for power take-off, through which a torque from the shaft is transmitted to the multipliers and alternators, and is subtended by the upper and lower bearing housings, mounted coaxially on the upper and lower supporting plates, which are rigidly attached to the foundation.

EFFECT: invention is aimed at increasing the power and productivity of the rotor with blades.
