over the last SiX years, 13 propulsion configurations have been
evaluated on models of a 7945 tonne (7820 ton) destroyer. This report pre-
sents a summary of how these 13 propulsion configurations and two other
configurations , which have been assessed analytically, would perform with
design propellers on a destroyer. In addition, analytical predictions have
been made for nine propulsion configurations on a 3505 tonne (3450 ton) frigat~
and six propulsion configurations on a 12192 tonne (12000 ton) cruiser. The

result of all these predictions is that su~stantlal power reductions at a
speed of 20 knots are possible on all three ship sizes, relative to
controllable-pitch propeller baseline configurations. In particular, the
delivered power of the destroyer could be reduced by as much as 20 percent,
the power of the frigate could be reduced by as much as 12 percent, and the
power of the cruiser could be reduced by as much as 15 percent.
The particular propulsion configurations which show the most substantial
benefits are propulsion pods with contrarotating propellers, bearing-in-
rudder post with controllable-pitch or fixed-pitch propellers, and contra-
rotating propellers with conventional shafts and struts.
Fixed-pitch propellers provsde up to 10 percent power reduction relative
to controllable-pitch propellers. Therefore, fixed-pitch propellers should
be used under all circumstances where backing and stopping can be accomplished
by reversing the rotation of the shafting.
Ln aciditionto the performance predictions discusses above, this report
discusses the technical status of these various propulsion configurations.
This report also has five appendices wnich contain: the details of the models
built and tested; the powering predictions based on custom stock propeller
experiments with 13 models; the projected powering performance for 15
propulsion configurations with design propellers; a brief summary of the
research which has been performed on podded propulsion; and a history of the
bearing-in-rudder post configuration.
