TWO-ROTOR COMPRESSOR Russian patent published in 1995 - IPC

FIELD: compressor engineering. SUBSTANCE: axes of symmetry of two symmetrical tree-blade rotors are arranged at the angle of 120°. Semi-profile of each blade is defined by a curve having the convex part going into the concave part. The convex part of the curve is defined by one forth of the distance between the rotor centers. The concave part is the curve defined by given equations in the rectangular coordinate system one of the axes of which is axis of the symmetry of the rotor. EFFECT: enhanced efficiency. 1 dwg
