Abstract : An experimental and analytical study was conducted in support of the HIBS program to determine the feasibility of explosively accelerating multiple gram-sized projectiles to 10 km/sec. Emphasis was directed toward developing and testing lightweight, low cost, and weaponizable devices using advanced explosive driver concepts. Problems were encountered with material properties, an unusual explosive driver startup phenomena associated with the new materials, and projectile breakup. A weaponizable device is however feasible. Best performance to date is the simultaneous launching of five 1-g steel and nylon projectiles to 7.5 km/sec in a lightweight device using Comp. C-4 explosive and argon driver gas at 59 psig initial pressure. (Modified author abstract)
