Design of a Free-running, 1/30th Froude Scaled Model Destroyer for In-situ Hydrodynamic Flow Visualization

Abstract

Hydrodynamic flow visualization techniques of scaled hull forms and propellers are typically limited to isolating certain operating conditions in a tow tank, circulation tunnel, or large maneuvering basin. Although cost effective, these tests provide a limited perspective on the interactions of the entire system. Full-scale testing, other the other hand, provides real world data but is costly. In between, a Froude scaled, free-running model of an existing hull form controls costs but also provides superior hydrodynamic data that can be translated more accurately to full scale. This thesis details the design and construction of a 1130th scale free-running model of the David Taylor Model Basin 5415 hull, the precursor to the ubiquitous Arleigh Burke Guided Missile Destroyer hull. The model serves as an experimental platform for advanced maneuvering and propeller crashback studies.
