Document Type and Number:
Japanese Patent JP5647411
Kind Code:
B2
Abstract:
An axial flow positive displacement gas turbine engine component (3) such as a compressor or a turbine or an expander (88) includes a rotor assembly (15) extending from a fully axial flow inlet (20) to a downstream axially spaced apart axial flow outlet (22). The rotor assembly (15) includes a main rotor (12) and one or more gate rotors (7) rotatable about parallel main and gate axes (16, 18) of the main and gate rotors (12, 7) respectively. The main and gate rotors (12, 7) having intermeshed main and gate helical blades (17, 27) extending radially outwardly from annular main and gate hubs (51, 53), circumscribed about, and wound about the main and gate axes (16, 18) respectively. Intersecting main and gate annular openings (10, 11) in the axial flow inlet (20) extend radially between a casing (9) surrounding the rotor assembly (15) and the main and gate hubs (51, 53). The main helical blades (17) transition from 0 to a full radial height (H) in a downstream direction (D) in an inlet transition section (28).
