The low-speed bluff body studies conducted on aeroelastic
models were extended by redesign of the installation in the West
Coast Research Corporation's subsonic wind tunnel at the U. S.
Naval Postgraduate School, Monterey, California. Improvements
included stiffer support base, redesign of the spring constraint,
and the use of eddy-current type displacement gages. In addition,
the model's lateral response data were monitored, conditioned and
recorded on one-inch magnetic tape in a voltage analog form.
The analog data were converted to digital form at a sampling
rate of 500 numbers per second for a period of eight seconds per
case in order to permit subsequent digital analysis in the Control
Data Corporation 1604 computer. The results of this digital
computation provided a numerical estimate of the spectral
distribution, which gives an insight into the character of the
random response of the aeroelastic structure due to the
aerodynamically induced unsteady air load.
