AHPCRC Research Highlighted at AUSA Symposium and Exhibition

"Equipping Force XXI" was the theme of this yearUs Winter Symposium and
Exhibition of the Association of the United States Army (AUSA). The AUSA
Symposium and Exhibition, held in Orlando, Florida, January 23-25 was designed
to bring together key players from the Army, industry and academia involved in
equipping Force XXI. Force XXI is the US Army of the 21st century which must
make adjustments in order to carry out its mission during a period of declining
resources. The key factor in equipping Force XXI, as stated by Secretary of
the Army Togo D. West Jr., is to rely "on a technological edge to overmatch our
adversaries." He also stated that in order "to maintain this edge, we must
continue to modernize."
The Army Materiel Command (AMC) is one of the key organizations leading the
Army into Force XXI. The AMC exhibit focused on the theme "partnering and
innovation" and demonstrated how AMC is using basic research, early technology
and advanced development, testing expertise and acquisition excellence to lead
the Army into Force XXI. The AHPCRC was featured in the Basic Research Station
of the AMC exhibit as an example of an ARO Center of Excellence and the
featured demonstration at the ARO station on the exhibit floor was the AHPCRC
simulations of the deployment and gliding performance of large parafoils. The
finite element computational studies on the behavior of large ram air
parachutes were displayed and presented (see Figure 3). The display was
staffed by Tayfun Tezduyar (Director, AHPCRC), Shahrouz Aliabadi (AHPCRC),
Frank Hurley (ARO), Keith Stein (Natick RDEC) and Major Jack Owens (US Army
Research Laboratory) (see Figure 4).

Development of finite element techniques capable of modeling fluid motion about
complex shapes with moving boundaries has been an important area of research at
the AHPCRC during recent years. These techniques are well suited for capturing
the physical phenomena associated with the dynamics of parafoils. The parafoil
effort is led by Tezduyar and William Garrard (Professor and Head, Aerospace
Engineering and Mechanics) along with TezduyarUs research team at the AHPCRC.
This highly visible effort is sponsored by ARO in collaboration with and
support of the US Army Soldier System Command and their contractor for the
Guided Parafoil Air Delivery System.
The AHPCRC display and presentation were well received at the AUSA exhibit.
GEN Gordon R. Sullivan (US Army Chief of Staff), during his keynote address,
stated that the Army is "working on a new ram air parachute with one of our
premiere universities." This research on the application of high performance
computing to modeling ram air parachutes is a collaborative project between
Natick RDEC and the AHPCRC. Mr. George T. Singley III, Deputy Assistant
Secretary for Research and Technology, also expressed his appreciation of the
AHPCRC ongoing research effort.

GEN Leon E. Salomon, the commanding general of AMC led several escorted tours
through the AMC exhibit. These included walkthroughs for GEN Sullivan, and
Secretary of the Army Togo D. West, Jr. Other walkthroughs were escorted by
LTG John G. Coburn (Deputy commander of AMC) for numerous US Army, government,
industry and public affairs assemblies.
The AMC exhibit was one of many display areas on the exhibit floor. Other
industry and Army exhibits were also on display in the AUSA exhibition. The
AUSA symposium had several talks focusing on relevant issues pertaining to
equipping Force XXI: Partnering with Government and Academia for Force XXI;
Army Digitization and Information Transport for Force XXI; Acquiring Force
XXI; Testing and Evaluation for Force XXI; Technology Generation for Force
