The objective of Project 30.5 was to provide instrumentation, electronic and self-recording, for obtaining air-blast and ground-shock loading and response of the structures employed by the various structures projects. Included was installation of transducers, recording of transducer signals, and presentation of the recordings as linearized time-dependent plots of the measured variable in the specified appropriate units. A total of 127 recording channels was utilized; of these channels, 75 were used for electronic recording on magnetic tape, 37 were used for self recording time-dependent guages, and 15 were peak-indicating guages. A basic description of the instrumentation employed by the Ballistic Research Laboratories in taking the structural measurements for Project 30.1, 30.2, 30.3, 31.4, and 31.5 is given.
