Samsung FPP 4000mm 4B

A Samsung Heavy Industries fixed‑pitch propeller (FPP) with a 4 m diameter, four blades and nickel‑aluminium bronze construction, designed for low‑speed diesel engines operating around 110 rpm. The supplied category identifies it as Fixed-Pitch Propeller, and it is normally installed at the aft end of the propulsion shaft outside the hull, directly converting shaft torque into propulsive thrust. In that role, its primary purpose is to provide forward or astern thrust with a blade pitch that is fixed by the propeller geometry. Unlike a controllable-pitch propeller, an FPP has no internal pitch-changing mechanism, so thrust reversal normally depends on reversing shaft rotation or another propulsion arrangement. Within the supplied list, neighbouring variants are distinguished by their model designations and naming, while the source does not state further model-specific hardware differences. No additional performance, approval or construction detail is inferred from the model code beyond the information supplied in the source record. For exact ratings, dimensions, settings, capacities, materials and variant-specific limits, refer to the manufacturer documentation for the exact figure.
