Abstract
Summary:
This report details the work carried out during a fundamental study into the generation of
transverse and longitudinal vortices in the working sections of wind tunnels. In the initial
phases of the project, effort was focused on the generation and measurement of longitudinal
vortex pairs to mimic the vortex system produced by the Westland Helicopter's Vane tip. The
results from this part of study have already been used in an EPSRC funded study of main rotor
blade-vortex interaction (BVI). Attention was then directed towards the development and
testing of a transverse vortex generator for studies of tail rotor BVI. The successful
demonstration of this generator has resulted in a follow-on EPSRC funded study of helicopter
tail rotor BVI in a larger wind tunnel facility
