ACQUISITION CYCLES Reclucing Cycle Times The committee identified the effects of long acquisition times (i.e., the time between program initiation and initial fielding) on programs and evaluated the implications for the defense aerospace infrastructure.

Finally, shorter cycle times would allow engineers to spend more of their time engineering and less on the busy work related to the acquisition process. Using Commercial Products and Processes DoD acquisition policies have made it difficult for defense systems to take advantage of the latest commercial cost benefits and dynamic advances in commercial technologies.

to product development; Using time-phased operational requirements; · Requiring demonstration of a technology prior to the start of formal acquisition; Placing priority on evolutionary acquisition strategies based on time-phased requirements, proven technologies, and demonstrated manufacturing capabilities; and Initiating formal acquisition at or between any of the formal development milestones. Continued efforts to reduce cycle time will be critical.

However, engineering talent is a rare commodity in today' s highly competitive technology marketplace, and firms are very reluctant to spend their scarce engineering resources for prototype programs without the prospect of profitability during production. Although the committee recognizes and strongly supports the contributions that prototyping can make to attract, train and retain skilled professional designers, after considering alternatives, the committee concluded that continuing activities from R&D to EMD through production and product support are essential for maintaining all of the skills and team experience necessary for the aerospace industry to produce new aircraft.

communications satellites and components fell by 40 percent as a result of satellites being placed on the State Department's list of controlled munitions in 1999 (Reinsh, 2000~. After meetings between congressional representatives, including the Armed Services committee, the Foreign Relations committee, and the appropriation subcommittees, and industry associations, funding for ODTC has been increased; the review process for satellite exports to the North Atlantic Treaty Organization (NATO)

Although computational fluid dynamics has made impressive strides in the last several decades and can define a best overall configuration, details must still be optimized. Finetuning engine inlets, exhaust systems, and wing-fuselage fillet configurations and minimizing interference shock effects at transonic speeds usually require testing in wind tunnels.

Second, management from industry and government must have confidence that CFD is a more efficient developmental tool than extensive wind tunnel testing. For the next 15 years, CFD and ground test facilities will be used in a complementary mode with no appreciable reductions in testing anticipated.

Planning for future technical resources must include maintaining these facilities. Fiscal pressures on the testing agencies are intensified by the continued decline in the use of aeropropulsion test and wind tunnel facilities.
