FIELD: engines and pumps.
SUBSTANCE: multiplexer turbine wheel for gas turbine engine is composed of mechanical gearing consisting of drive body (6) with turbine blades (8) fitted on its outer peripheral surface. Inner working surface of the body (6) represents an epitrochoidal outline (7) described by the vertices of driven three-angled rotor. Crank (2) is arranged inside rotor (4) and aligned therewith and offset relative to barrel (3) integrated therewith. Axis of said barrel is aligned with the centre of said epitrochoidal outline (7). Radii of cup (3) and crank (2) relate as 2:3 while eccentricity makes half the radius of cup (3).
EFFECT: higher load capacity, longer life.
