The purpose of the study is to gain insight into the unsteady loading imparted to lifting surfaces immersed in structured turbulent flows. The study will experimentally explore the dependency on the physical characteristics of the oncoming flow and the hydrofoil geometry. New instrumentation will be developed with an extended range of frequency resolution to provide greater insight into the correlation between the underlying flow physics and the resulting unsteady force spectra.
The main benefit of the outcomes of this project will be to contribute to improved control surface design for submarine and other submerged naval platforms. Reduced vibration and radiated noise will result in improved structural design and signature performance.
