Cycloid propeller for ship

摘要

The propeller has a centred propeller rotor (1) and a propeller blade (3) fixed on a blade shaft (6) controlled by first control parts (4,18). The single propeller blade consists of two parallel parts (8,9) linked to each other. The main or central part (8) is joined to the blade shaft as well as to the first control parts. The second blade part (9) has its own adjustment rods (11,12,17) to vary the blade profile during a revolution of the propeller rotor. The curvature of the profile chord (51) or centre line is itself capable of enlargement at a position of the blade with bulge-side flow.
