Blast Exposure and Injury Correlation Using Blast Sensor Data

IED attach on vehicle

Challenge

What conditions cause traumatic brain injury from air blast exposure? DARPA blast gauges recorded overpressure data from combat environments providing a quantitative link between blast exposure and medical outcomes.  

Solution

ARA used blast gauge data to reconstruct the full 3D blast exposure on each subject. By calculating the blast exposure variations across an individual, more meaningful correlations with injuries can be established. ARA uses a range of tools from engineering tools to full 3D computational fluid dynamics simulations for the project.

Impact

Significant advances in reconstructing IED attacks and other blast events using point data from blast sensors such as the DARPA blast gauge can be used to create more meaningful correlations for short term and long term injury patterns.
