Flow visualization, surface mounted pressure transducers and hot-wires anemometers have been used to measure the leeside vortex flowfield on an ogive-cylinder at high angles of attack. The results show that there is a high degree of flowfield unsteadiness which arises due to several phenomena. The phenomena include large scale von Karman-type shedding, high frequency pressure and velocity fluctuations indicative of the presence of free shear-layer vortices, and a vortex interaction. The effects of position along the body, angle of attack and wind tunnel speed on the surface pressure and velocity in the wake have been investigated.
