Abstract
Previously determined ignition and growth reactive flow model parameters for detonating LX-17 (92.5% triaminotrinitrobenzene [TATB], 7.5% Kel-F binder), PBX 9502 (95% TATB, 5% Kel-F), and pure ultrafine TATB were used to calculate the results of two new experiments. Continuous detonation velocity measurements were made using embedded fiber optic (EFO) diagnostic probes in ambient temperature (25 degrees C) LX-17 cylinders of various diameters. In double-cylinder corner turning tests, the times required for cold (-54 degrees C), warm (75 degrees C), and 25 degrees C LX-17, PBX 9502, and ultrafine TATB detonation waves to propagate around 90 degrees corners were measured. The calculated detonation velocities and arrival times agreed closely with the measurements from both experiments.
