Abstract
The paper deals with tip-modified propellers and the methods
which, over a period of two decades, have been applied to develop
such propellers. The development is driven by the urge to increase
the efficiency of propellers and can be seen as analogous to
fitting end plates and winglets to aircraft wings. The literature
on four different designs is reviewed: the end-plate propeller;
the two-sided, shifted end-plate propeller; the tip-fin propeller;
and the bladelet propeller. The conclusion is that it is indeed
possible to design tip-modified propellers that, relative to an
optimum conventional propeller, have efficiency increases of a
reasonable magnitude in both open-water and behind-ship conditions.
