University of Wisconsin--Madison

Overview

The University of Wisconsin--Madison has performed multiple tests on the turbine in various stages of disassembly. Current Plans are to perform substructuring predictions with some of these models, for instance, fixing one blade to a rigid boundary condition and attaching a blade to the disassembled turbine. Note that M.S. Allen, the PI of the Structural Dynamics Research Group at UW-Madison has moved to BYU: http://byusdrg.com

Summary of Ampair Tests

• Dan Rohe's thesis contains an excellent discussion of the experiments performed at UW-Madison and the difficulties encountered. A second set of tests was performed at Sandia (will post that data when we are able) and far better results were obtained. His thesis is available below.
