The report extends the available data on the velocity structure within a trailing line vortex to large distances downstream of the generating wing. Data are presented to show the variation of both axial and tangential velocity with tunnel speed and trailing vortex strength. Specifically, data are presented at downstream distances of 10 and 26 chord lengths behind a semispan wing set at 4 and 12 degree angle of attack for tunnel speeds of 50 and 70 mph. (Author)
