RESULTS FROM A SET OF LOW-SPEED BLADE-VORTEX INTERACTION EXPERIMENTS

The results of a Blade-Vortex Interaction (BVI) experiment are present ed. The experiments were the second series to be carried out at Glasgo w University (see Kokkalis and Galbraith 1986,1987), and reflect impro vement to the facility. These improvements have resulted in sufficient resolution to observe clear evidence of vortex passage and propagativ e disturbances caused by the BVI. Additionally the quality of the pres sure data permitted a meaningful assessment of force and moment coeffi cients, and a clear correspondence between their detailed time histori es was observed. The data obtained are also compared with the results of previous studies, and qualitative and quantitative similarities are discussed.
