Abstract: Very short pulse duration, high pressure shock initiation experiments using electrically driven plastic flyer plates were performed on the explosives LX‐10 (95% HMX, 5% Viton binder by weight) and LX‐16 (96% PETN, 4% FPC 461 binder by weight) to measure threshold flyer velocities for detonation initiation. For LX‐16, threshold velocities were determined for various flyer materials, thicknesses and diameters. This data was calculated using the Ignition and Growth reactive flow model parameters previously determined for LX‐10 and LX‐16. Good calculated agreement with experimental threshold velocities was obtained by increasing the maximum fraction ignited during high pressure shock compression compared to the fraction ignited by lower pressure sustained shocks.
