Airplane Vibration Recorder
This paper describes a portable film recorder capable of simultaneously recording 13 variable-area tracks on 35-mm film. It is intended for use in the analysis of airplane vibration or similar studies in which it is desirable to record disturbances (mechanical, acoustical, or electrical) from a number of sources in such a manner that the resultant record can be analyzed for frequency, amplitude, and phase relation. Film speeds of 12, 6, or 3 in. per sec are available.
