Abstract:
1. A multi-projectile assembly, comprising: at least a first projectile portion; at least a second projectile portion; and a multi-staged radial braking and tether restraint system that interconnects the at least a first and second projectile portions such that spin-generated forces imparted on the assembly cause the at least a first and second projectile portions to radially expand away from their original center of rotation up to a finite expansion limit defined by the multi-staged radial braking and tether restraint system wherein the multi-staged radial braking and tether restraint system applies substantially no resistance to the at least a first and second projectile portions until they have moved a first predetermined radial distance away from their original center of rotation at which point the multi-staged radial braking and tether restraint system begins applying a second force greater than the substantially no resistance to the at least a first and second projectile portions causing the at least a first and second projectile portions to expand from center at a decreasing rate of speed until the finite expansion limit is reached.
