HONEYCOMB ROTOR Russian patent published in 2008 - IPC F04D29/18 

FIELD: engines and pumps.

SUBSTANCE: honeycomb rotor incorporates a hub or a bush with a central axis, at least, one tubular cylinder (TC) arranged concentric on the hub and, at least, four connecting elements (CE). The said elements pass through the hub and TC or between adjacent TCs and have the lines of connection to the hub and TC along the rotor length. CE and TC form a trapezoid in the rotor cross-section with lateral sides being formed by CEs and the bases formed by the TC sections between adjacent CEs. The trapezoids are arranged one above the other forming the rotor honeycomb structure. The CE connection lines along the rotor length are helical lines relative to the hub central axis. Trapezoid cross-section helical channels are formed between TC and CE. The number of CEs between the following adjacent TCs increases with the increase in their diameter. The total surface area of the said helical channels is two or more times greater than the rotor total inlet surface. The rotor is additionally furnished with a truncated-cone element connected to the inlet of the extreme outer TC.

EFFECT: improved performances.
