Application of Sound Recording Techniques to Airplane Vibration Analysis

This paper describes methods which have been developed for analysis of the various vibration components present in airplane structures. The complex wave forms are recorded on standard motion picture sound negatives during flight. These films later, after proper development, are analyzed electrically, making possible a complete analysis on the ground and thereby reducing materially the time devoted to flight test, and also simplifying the process of analysis of complex wave forms.
