Dr. Thomas F. Tureaud

Dr. Tureaud joined the staff of Vehicle Control Technologies, Inc. In January 1996 and has actively supported a number of programs including:
Development of software to analyze and predict unsteady 3D cable motions.
Development of methodology and software for the design of airborne dirigibles.
Support for hydrodynamic design of underwater vehicles.
Director of VCT's experimental testing.

Dr. Tureaud was responsible for the development of Draper Laboratory's fluid dynamic capability, and because of this he was the principal investigator on numerous Laboratory programs involving fluid dynamics, fluid acoustics, hydrodynamics and experimental techniques. Each program was designed to both enhance the Laboratory's primary ability as well as to investigate new research and technology areas. He established the Laboratory's hydrodynamic computational library, which included a broad range of analysis codes and data base access. He directed several laboratory-funded, University basic research projects which included MIT, Tufts and University of Notre Dame. These projects included studies in propeller foil design, high efficiency propulsion, two-body effects and fluid-acoustic research.

Performed post-trail data analysis and comparison to model prediction for DARPA s 44" autonomous UUV. Developed corrections for pod appended bodies and added these to the UUV hydrodynamic model. Calculated surface pressures of the UUV and used results to implement a passive cooling system on the afterbody. [1988-1989]

Contributed to the hull form, control appendage and propulsion design of the Submarine Off-board Mine Search System (SOMSS). Performed parametric studies for maneuvering optimization and robustness of the vehicle. Used axisymmetric RANS codes to calculate hull form turbulent flow calculations for resistance and wake determination. Used potential flow codes for calculations of appendage center of pressure and torque load determinations. [1990-1992]

Acted as technical director of several projects under the DARPA SubTech program, including projects that supported maneuvering and propulsion analysis of the New Attack Submarine. [1990-1993]

Performed and contributed to pioneering research in fluid acoustics, which investigated mechanisms of sound transfer and sound receptivity in laminar and transitional boundary layers using Navier-Stokes calculations. These results were published in ASME and AIAA Journals. Author or co-author of more than 25 technical reports and journal articles. [1985-1994]

3D CAD/CAE Experience
Dr. Tureaud has experience in developing and writing FORTRAN based fluid dynamic and hydrodynamic analysis codes. These developed codes include unsteady potential flow for arbitrary shaped appendages, two- and three-dimensional Navier-Stokes codes, including development of various turbulence models and various semi-analytic based hydrodynamic codes. He has written several interface code based on IGES, DXF and NURBS, which allow transfer of data between larger codes. He is currently involved with the development and modification of VCT's hydrodynamic predictor and trajectory codes GEORGE and TRJv. In addition, he is experienced in programming and utilizing MATLAB based analysis. He is capable in UNIX, VAX, Cray, Macintosh, DOS and RISC based systems.

He has used third-party codes at length during his career, hydrodynamic related codes are: VSAERO, USAERO, DTNS, HYDAT, Alias, Animator, AVS, I3G, FastGen, RAMBO, Plot3D and others.
