Abstract

The experimental results of a parallel Blade-Vortex Interaction (BVI) study are presented. The quality of all pressure data reflects improvements in the Glasgow University BVI facility and in the method of reducing 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, and also allows for a correlation between vortex trailing edge passage and force and moment perturbations.
