Popis:	A stereoscopic PIV system has been developed for large-scale wind tunnels in National Aerospace Laboratory (NAL). The system and its components are introduced, and important technical issues and future plans are addressed. Some test results obtained by the PIV system in NAL 6.5 m x 5.5 m low speed wind tunnel, including jet-engine exhaust/external flow interaction and helicopter blade-vortex interaction, are presented to show capability, measurement accuracy, and limitations of the system. The results show that the present PIV system is useful for acquiring velocity field data in industrial-type tests as well as aerodynamic research-oriented experiments. The velocity measurement capability will be provided to public users of the wind tunnels after conducting detailed evaluations of measurement accuracy. 資料番号: AA0048061007 レポート番号: JAXA-SP-04-008
