DATA HANDLING SYSTEM IN SUPPORT OF ANTENNA VIBRATION PROJECT

Abstract

The low-speed bluff body studies conducted on aeroelastic models were extended by redesign of the installation in the subsonic wind tunnel. Improvements included stiffer support base, redesign of the spring constraint, and the use of eddy-current 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 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.
