The current report summarizes its findings for the 2009-2010 period, during which 96 volunteer experts in fields of science and engineering participated in the following activities: visiting ARL annually, receiving formal presentations of technical work, examining facilities, engaging in technical discussions with ARL staff, and reviewing ARL technical materials. The Board continues to be impressed by the overall quality of ARL's technical staff and their work and applauds ARL for its clear, passionate concern for the end user of its technology -- the soldier in the field -- and for ARL's demonstrated mindfulness of the importance of transitioning technology to support immediate and longer-term Army needs.

methods to reveal the neural basis of "Shoot/Don't shoot" behavior; • eadership in the work in quantum detectors and III-nitride materials for sources and detectors, L in acoustic processing and electromagnetic field sensing, and in semiconductor power switching and conditioning devices; • tate-of-the-art work on the compressor-tip-injection stall control that couples experimental data S and computational fluid mechanics and will enable the industrial design community to improve gas turbine fuel economy and reduce compressor stall; windage work in high-speed gear systems that promises to improve gearbox efficiency across a wide range of vehicles; and groundbreaking work on microautonomous systems; • he clear evolution of armor in various ways over the years as the threats have also evolved: T in particular, improvised explosive devices are creating new demands on armor. Advances in materials and computational tools have made possible new approaches to address passive armor protection.

COMPUTATIONAL AND INFORMATION SCIENCES DIRECTORATE Several technology issues have cut across multiple ARL directorates, but with particular impact on the Computational and Information Sciences Directorate (CISD)

From page 4... ...
The Army needs to leverage technology to respond to events like the rise of asymmetrical warfare and improvised explosive devices. In CISD's domain, as in the Army more broadly, change in technologies occurs exceedingly rapidly.

Most critically, the group needs to develop a strategic plan directing the choice of research thrusts and projects that will enable the program to contribute to basic science and to warfighter applications. The soldier performance group has overseen the development of two state-of-the-art facilities: the Tactical Environment Simulation Facility and the Environment for Auditory Research.

SEDD has addressed this responsibility by increasing its in-house research efforts in several areas, such as wide bandgap materials, image processing, flexible displays, and battery chemistries, while moving on from unattended ground sensors and sensor integration, and transitioning silicon carbide device research from in-house to external projects. Significantly, these changes are guided by a clearly stated long-term vision for each of the major SEDD mission areas.

The system-of-systems analysis program and the Modular UNIX-based Vulnerability Estimation Suite, or MUVES 3, program continue to cause significant concern, but with appropriate focus these programs can grow to become foundations of the SLAD analysis capabilities. In wartime, rapid response to soldier-in-the-field challenges is imperative.

Some of VTD's high-quality technical work is clearly an important contribution to the overall technical community. For example, the compressor-tip-injection stall control work that couples experiment data and computational fluid mechanics is state of the art and will enable the industrial design community to improve gas turbine fuel economy and reduce compressor stall.

From page 9... ...
Modeling is also critical to system design; good models are the key to insight into the underlying physics, from which meaningful functional and performance metrics can be developed and understood. VTD should consider undertaking an effort in each of the following emerging technology areas: mesoscale power sources, such as small fuel cells and gas turbines; the analytical modeling of physical processes such as combustion; and simulators for the training of operators of remotely piloted air and ground vehicles.

Much of WMRD's program in energetics materials modeling appears to emphasize quantum chemi cal modeling heavily, and experimental investigation and verification appear to receive less emphasis. The energetics materials modeling effort should be focused on a few challenging problems selected from appropriate length scales.

Researchers in the Lethality Division should be encouraged to identify customer proponents to enhance the likelihood that standard project funding will follow closely after the success of the initial project.
