• Note (General): Measurements were made to investigate the three dimensional structure of the leading edge vortex formed on a delta wing with a 60deg sweep. The behavior of the vortex was studied by means of a lift measurement, surface pressure measurements and flow visualization tests. Mean velocities and velocity fluctuations were measured using a laser two-focus velocimeter(L2F). In this paper, the flow pattern inside the secondary separation vortex is shown from the results of the above measurements. The relation ship between the mean velocities and the velocity fluctuations are also shown. Since this was the first time L2F had been usde in the NAL gust wind tunnel, the problem of the present experimental method using the L2F is discussed.; 資料番号: NALTR1087000; レポート番号: NAL TR-1087
