An Innovative Confined Space Blast Wave Measurement System

Physical Sciences Inc. (PSI) proposes to develop an innovative blast wave measurement system that will characterize the three-dimensional nature of the blast inside an enclosed space. The innovation of our approach is in the design of the sensor modules that provide three-directional time resolved measurements of the blast wave static pressure and the blast front propagation direction. Using data to be obtained with our omni-directional blast wave measurements system in conjuction with data analysis algorithms, our system will determine the essential desired blast wave parameters. The Phase I program will concentrate on identifying the requirements of the system, refining the design to achieve these requirements, and assessing various transducers capable of achieving the requirements. PSI will also identify all the necessary hardware and software to characterize a 3-D model of the blast. During the Phase II program, PSI will fabricate the design, integrate modeling software, and produce a prototype to be validated during actual live fire testing at an Army facility.
