Report No. 623, 1947

The research series spans all four boxes of the collection and is arranged into seven subseries based on the subject of the research. These are the original subjects assigned by Pugh. This series contains an account book, journal articles, notebooks, and numerous research reports. The account book was used to keep track of various grant funds. The notebooks contain original graphs, notes, and measurements of Pugh's early research in the Hall Effect, war time explosives, and fragment velocity. The majority of the series consists of reports titled "Fundamentals of Shaped Charges," which were written as part of ten government contracts from 1946-1962. These reports cover research about the effectiveness of protective materials against shaped charges, increasing the consistency of the explosion force of the charges, and measuring their blast. The longest contract was DA-36-061-ORD-513, which produced twenty-five reports over six years (1956-1962). An index of the individual titles of the articles included in this series can be found at the end of this document.
