Leading-edge vortex formation and breakdown have been measured over a periodically plunging non-slender delta wing at a high angle of attack, using a three-dimensional particle-tracking method. A very rare type of vortex breakdown in the form of a double helix has been captured in the phase-averaged flow at a specific phase of the oscillation cycle.
