The Board understands that a group that visits a laboratory for a relatively brief period each year has only a partial understanding of the factors that influence or limit the laboratory's program, and so it may make some recommendations that are not feasible or optimal. The Board and its panels are working jointly with ARL to improve the feedback loop so that the panels receive annual updates on actions in response to, or regarding rejections of, their various recommendations.

RESPONSIVENESS TO PARTICULAR RECOMMENDATIONS IN THE 1999-2000 REPORT Improvements Made to Some Outdated Instrumentation at ARL's White Sands Site The Board's 1999-2000 report raised some concern that the effectiveness and efficiency of the Survivability and Lethality Analysis Directorate (SLAD) were being impeded by outdated instrumentation at its site in White Sands, New Mexico.

The Board suggests that VTD carefully prioritize the planned code developments in terms of the likelihood that they will produce real contributions, at useful points in the time line for the experimental program, for understanding the flow physics involved during stall and recovery through flow injection. Continued Improvements to the Zahl Physical Sciences Laboratory Another opportunity identified in the 1999-2000 Board report stemmed from the outstanding quality of the then-new Zahl Physical Sciences Laboratory in Adelphi, Maryland.

SEDD has been active in MMW technology for a long time, and with its industrial and university collaborators (mostly through ARL's Advanced Sensors federated laboratory consortium and the subsequent Advanced Sensors CTA) , it has produced state-ofthe-art monolithic microwave integrated circuit (MMIC)

This cognizance on the part of the Army positions ARL to quickly ramp up the needed R&D efforts when it is appropriate to transition such frontier research toward an implementable technology. Because ARL's basic research programs support many of its postdoctoral researchers and its collaborative efforts with academic S&Es, those programs are also the breeding ground for many of the laboratory's future leaders, those people with solid R&D credentials and a long-term vision of Army technology.

In fact, the panels reviewing VTD and SEDD explicitly noted the quality of their interactions with their respective ARL directorates. The panel reviewing VTD, after its 2002 meeting, concluded that this was one of the most valuable reviews it had conducted at ARL: the presenters were generally well prepared, they allowed ample time for questioning, and the interchange between presenters and panel members was constructive.

Another example of enabling research, not quite as far along, is WMRD's work toward a processing method for structural polymer composites. It is quite certain that, because of their high strength-toweight ratio, polymer-based composite materials will play a major role as structural parts in rotorcraft, unmanned aerial vehicles, and FCS ground vehicles.

The rate of flow is much faster than in the permeation type of Darcy flow found in the standard VARTM process. After the polymer sets, the secondary bag is peeled from the part, leaving a minimum of waste material.

The Board recommends that ARL check that these internal and external ties are being pursued. Crack Growth Modeling Another long-term effort that has not been discussed in previous Board assessments is VTD's effort directed at physics-based modeling of threshold fatigue crack growth for metallic materials.
