Turbomachine flow improvement system

A turbomachine (2) includes a housing (13) that defines a flow path (16), and a stage (21,22) arranged within the housing (13). The stage (21,22) includes a plurality of rotating airfoil members and a first (36, 43) plurality of stationary airfoil members (46). A second plurality of stationary airfo...

Zusammenfassung:	A turbomachine (2) includes a housing (13) that defines a flow path (16), and a stage (21,22) arranged within the housing (13). The stage (21,22) includes a plurality of rotating airfoil members and a first (36, 43) plurality of stationary airfoil members (46). A second plurality of stationary airfoil members (50) is arranged directly adjacent to the first plurality of stationary airfoil members (46). A flow improvement system (100) is associated with each of the first and second pluralities of stationary airfoil members (46,50). The flow improvement system (100) establishes a predetermined clocking of each of the first plurality of stationary airfoil members (46) relative to each of the second plurality of stationary airfoil members (50) to improve flow characteristics along the flow path (16).
