RUSSIAN WIND TUNNEL TESTS FOR BOEING PROVE SUCCESSFUL

 RUSSIAN WIND TUNNEL TESTS FOR BOEING PROVE SUCCESSFUL
 SEATTLE, July 14 /PRNewswire/ -- The first part of a cooperative


test program between Boeing Commercial Airplane Group and Russia's Central Aero-Hydrodynamics Institute, commonly referred to as TsAGI ("saw-ghee"), was successfully completed July 1, the company announced today.
 Two different scale models of Boeing aircraft were tested in TsAGI's T-128 transonic wind tunnel at its headquarters in the aviation center of Zhukovsky on the outskirts of Moscow. The program included an evaluation of the wind tunnel performance capabilities and the accuracy of the data acquisition system. The wind tunnel's unique adaptive wall system was utilized.
 Boeing Commercial Airplane Group Senior Vice President Benjamin Cosgrove said, "We are very satisfied with the performance of the TsAGI wind tunnel and are impressed with the knowledge, dedication and professional attitude of the TsAGI personnel. We intend to explore other capabilities of mutual benefit to Boeing and TsAGI." Final assessment of the initial test results will be performed by Boeing following compilation of the data by TsAGI.
 TsAGI's T-128 transonic wind tunnel has several unique capabilities, including the potential for testing at high "Reynolds" numbers while using "adaptive wall" techniques. "Reynolds" number is a measurement of the characteristics of airflow over a surface, in this case a wing. "Adaptive wall" techniques allow control of wind tunnel airflow by use of perforations in the side walls.
 TsAGI is a governmental aerospace research, development and test institute serving various components of the Russian aviation industry, including design bureaus, manufacturing facilities and other research centers.
