Embedded fiber Bragg grating pressure measurement during thermal ignition of a high explosive
- Los Alamos National Lab. (LANL), Los Alamos, NM (United States)
A high-speed fiber Bragg grating based pressure-only measurement is reported for the high explosive PBXN-9 under thermal initiation conditions. During exothermic thermal runaway, an explosion rise time of 500 μs reaching a peak pressure of 660 MPa is measured. Lastly, the approach offers a direct measure pressure diagnostic useful for quantifying reaction violence for high explosive chemistry.
