Hydroelasticity of High-Speed Planing Craft Subjected to Slamming Events
Abstract
ABSTRACT: The goal of the proposed eort is to gain a basic scientic understanding of the uid-structure interaction resulting from slamming of small craft in waves. The PI plans toinvestigate the cause and eect relationship between the hydrodynamic loading on aplate, meant to model the bottom plating of a high-speed hull, and its response on thestructure and conversely, the eect of the structural response on the peak pressures.The anticipated outcome on DoD capabilities is the improvement of design of smallcraft, both manned and autonomous, by decreasing the total weight of the vessel andincreasing the vessel s operational envelope.The ve main objectives of this research proposal are:1. To perform wedge water entry experiments on highly-exible wedges to measurethe spray root, pressure, analyze the eects of material properties/congurationson deformation, and determine when tightly-coupled simulations need to be per-formed.2. To develop a theoretical basis for estimating the pressure eld on the bottomof a V-shaped hull entering the water vertically by measuring the instantaneouslocation of the water line.3. To perform towing tank experiments of high-speed craft slamming into waves. Ex-periments will be performed using GPPH and generic hull forms with interestingfeatures (the latter in support of Stefano Brizzolara). These carefully controlledmotions will allow for validation of computational models and pinpoint the keyparameters that aect the slamming pressure and structural response.4. To develop theoretical/computational design tools for the design of the wedgewater entry experiment. These tools will include nonlinear plate nite elementsand a suite of hydrodynamic theories such as Wagner and Vorus.5. To develop an FSI solver for slamming of high-speed craft in collaboration withStefano Brizzolara.This project will be conducted in collaboration with Fred Stern (Iowa) and StefanoBrizzolara (VT).The DOD Policy Memo on Fundamental Research dated May 24, 2010 provides guidance toensure that DoD personnel will not restrict disclosure of the results of fundamental research.Virginia Tech considers the scope of the proposed research to be fundamental research andanticipates there will be no publication approval or other requirements in the award thatwould restrict disclosure of the research results.
