Comments: Experiments are automated using a Labview user interface, as
shown in Figure 1.5i, and standard data acquisition instruments monitor signal
strength, rotation speed, torque and local pressures in both short and long wind
tunnels. Motor drivers, pump and a “long wind tunnel observation window” are
shown in Figures 1.5j - 1.5l without further comment.
