Mb. Horner et al., AN EXAMINATION OF VORTEX CONVECTION EFFECTS DURING BLADE-VORTEX INTERACTION, Zeitschrift fur Flugwissenschaften und Weltraumforschung, 17(3), 1993, pp. 189-195
The experimental results of a parallel Blade-Vortex Interaction (BVI)
study are presented. The quality of all pressure data reflects improve
ments in the Glasgow University BVI facility and in the method of redu
cing and presenting data. Pressure histories clearly track the passage
of a vortex-associated disturbance across the aerofoil. Tracking this
disturbance permits an examination of vortex convection velocities, a
nd also allows for a correlation between vortex trailing edge passage
and force and moment perturbations.
