Propeller for turbine engine e.g. open rotor type turbine engine, of aircraft, has hub comprising two annular type portions that are fixed to each other and defining part of recess opening

摘要

The propeller has a hub (40) comprising recess openings (44) for receiving roots of blades, and two annular type portions (40a, 40b) that are fixed to each other. A part of each recess opening is defined by the two annular type portions, where the two annular type portions comprise an interface plane (50) orthogonal to longitudinal axis (3) of the propeller. The interface plane constitutes a symmetry plane for providing the two annular type portions.
