摘要：

The circulation distribution of a wing tip vortex as a function of the spanwise coordinate was measured directly by an ultrasound technique using a rectangular acoustic path. The vortex was generated by a blunt-ended half wing, and the measurements were made at four chords downstream of the trailing edge. The circulation distribution achieved its highest level when the rectangular integration path completely surrounded the vortex. It decreased rapidly through the vortex center before reaching nearly zero when one side of the integration path traversed through the vortex.
