A Gamma Probe Technique to Determine Aircraft Ballistic Hardness Against Small Arms Fire.
Abstract
The feasibility of using a gamma-ray probe to determine the amount of ballistic protection provided by aircraft indigenous armor against small arms fire has been demonstrated. A scintillation spectrometer is used to measure the areal density of indigenous armor by discrimination of the Cs 137 spectrum. An analytic relationship is used to determine the amount of small angle Compton scattered photons and unattenuated photons detected by the spectrometer. Known values of areal density are compared with measured results. Results are given for the profile scan of simple geometric arrays and aircraft flight instruments. Methods are proposed for ballistic correlation and results are applied to a proposed prototype. (Author)
