Various measurements under ambient conditions are presented for LX-17. The size (diameter) effect has been measured with copper and Lucite confinement, where the failure radii are 4.0 and 6.5 mm. respectively. The air well corner-turning, has been measured with an LX-07 booster. and the dead-zone results are comparable to the previous TATB-boosted work. Four double cylinders have been fired. and dead zones appear in all cases. The steel-backed samples are faster than the Lucite-backed samples by 0.6 mu s. Bare LX-07 and LX-17 charges of 12.7 mm radius were fired with air gaps. Long acceptor regions were used to truly determine if detonation Occurred or not. I-lie LX-07 booster crossed a 10 mm gap with a slight time delay. Steady-state LX-17 crossed a 3.5 min gap but failed to cross a 4.0 mm Pap. LX-17 charge with a 12.7 min radius run after the booster crossed a 1.5 mm gap but failed to cross a 2.5 mm gap. Timing delays were measured where the detonation crossed the gaps. The Tarantula model is introduced as embedded in reactive flow JWL + + and Linked Cheetah V4, mostly at 4 zones mm(-1.) Tarantula has four pressure regions: off, initiation. failure. and detonation. The physical basis of the input parameters is considered,
