A two-component, backscatter laser anemometer was employed in a wind-tunnel test to obtain velocity measurements about a test missile that consists of a tangent-ogive nose and cylindrical body. Crossflow measurements were obtained by reflecting the laser beams entering the wind tunnel off a mirror behind the missile to align the beams to the body axis. Measurements at pitch angles of 22.5 degrees high angle symmetric body vortices present and 37.5 degrees asymmetric body vortices present are presented in tabular form. The directional ambiguity in the velocity components has been resolved for one case and the resulting velocity vector crossflow plot presented. Side-force measurements are included.
