A propeller assembly (10, figure 1) comprises a partial hub 12 having a set of clamps 30 selectively operably couplable (e.g. fastened, bolted) to a backing plate 20. The backing plate has a set of partial root seats 22 and each clamp defines a complementary second partial root seat. A root seat 24 is formed when a clamp 30 is coupled to the backing plate 20 and a root (70, figure 4) of a propeller blade (14) is received within the root seat 24. The backing plate may be at the rear or front side of the propeller and provides an engine mounting surface. The propeller blade may be line-removable (removed and replaced in the field), providing cost and maintenance advantages. The assembly (10) may be an aircraft propeller assembly, or any structure or craft, to which a propeller, turbine or fan having at least one blade is fitted. A retainer (86, figure 4) may be mounted to an outer periphery of the backing plate 20 and clamp 30 to retain the propeller blade root (70) within the root seat 24. A pre-loaded bearing assembly (80) may allow propeller blade rotation (e.g. pitch control) within the partial hub. |
