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.
