Title:
U.S. Army Combat Capabilities Development Command (DEVCOM) Armaments Center (AC) Photonic Doppler Velocimetry Cylinder Expansion Testing
Report Date:
2022-11-29
Abstract:
The cylinder expansion (CYLEX) test is used to characterize the work output of explosive formulations for use in modeling and simulation efforts as well as to provide calculated Gurney constant estimates at specific volume expansions. As there is currently no overarching standardization agreement or other reference dictating the methodology of this experiment, there is some flexibility in how CYLEX testing can be conducted. As a result, differences in methodologies often influence experimental observables and can significantly increase overall uncertainty if not documented properly. Documenting the procedures, data reduction methodologies, and testing parameters will allow for simplified experiment replication. This technical report details the methodology currently employed at the U.S. Army Combat Capabilities Development Command (DEVCOM) Armaments Center (AC), Picatinny Arsenal, NJ. The procedures necessary to accommodate specific material callouts are discussed and the details regarding how the dimensional data was captured are explained. The photonic Doppler velocimetry (PDV) probe setup and general procedure are also conveyed.
