Measurements of helicopter rotor wake flow were made at low advance ratio. Both steady and nonsteady data were taken in the wake using 3-D hot-film anemometry. Emphasis was placed on the presentation of the data. Motion pictures were obtained from the computer plots of the experimental velocity data.
