It is the prime objective of this paper to review critically some apparently well-established ideas on propeller design, with particular reference to the high-speed propeller. In its non-cavitating version, the latter is usually a free-running non-optimum propeller, in which both advance and rotational speeds are so high that it is extremely difficult to avoid cavitation, even under ideal inflow conditions. Alternatively, in its fully cavitating version, certain design requirements are known to exist, which have to be fulfilled, if this type of propeller shall be able to compete with waterjet propulsion systems. As a great deal of effort is spent nowadays in optimizing the latter, the propeller designer must be increasingly aware of the basic similarities as well as the fundamental differences in the mechanism of operation of the open propeller and the duct pump.
