51 RECAP OF THE FINDINGS AND RECOMMENDATIONS OF THE NATIONAL AERONAUTICAL TEST FACILITIES STUDY The decision to build high Reynolds number subsonic and transonic tunnels must balance the need for more-capable facilities with specific performance parameters, the costs of building and operating new facilities, and the economic benefits that are likely to result. Based on the analyses conducted by the NFS; other factors discussed in this report; and the benefits that the United States could derive from the tunnels in terms of balance of trade, employment, and economic activity, the ASEB recommends proceeding with the design and development of new subsonic and transonic facilities while more fully exploring the items recommended herein for further study.

These actions go beyond the recommendations contained in the NFS report. The Wind Tunnel Program Office should conduct trade studies to evaluate design options associated with the proposed new low speed and transonic wind tunnels (see Recon~nendation 2-~.26 In addition, the Wind Tunnel Program Office should ensure that the new transonic arid low speed facilities will be able to adequately support development of supersonic aircraft such as high speed civil transports by investigating flight characteristics during takeoff, acceleration, transonic flight over land, and landing.

Even with new facilities, scaling of ground test results will still be necessary to accommodate full-scale simulation of very large or innovative aircraft designs that may be developed in the future. Coordinated efforts to develop improved scaling methods that use wind tunnel testing, computational methods, and flight tests should be expanded.

Recommendation 6-3: The proposed low speed and transonic wind tunnels should be acquired using the most efficient combination of federal and commercial acquisition practices. SITE SELECTION Finding 6-4: For facilities such as the proposed low speed and transonic wind tunnels, which will require large technical staffs and huge amounts of energy, selection of a less-than-optimum site has the potential to degrade the efficiency and increase the cost of facility construction and operation, particularly if power availability restricts wind tunnel operating hours.

SCOPE OF C==NT STUDIES Finding 6-6: The National Facilities Study and this National Research Council study have not analyzed requirements for many types of important aeronautical test facilities, such as vertical flow spin tunnels, rotorcraft whirl towers, computational facilities, and flight test facilities. Recommendation 6-6: The results of the National Facilities Study and this National Research Council study should not be used to assert that types offacilities that were outside the scope of their deliberations are unimportant to the future of the U
