Sculpted reactive liner with semi-cylindrical linear open cells

  • US Patent No. 8387539
  • Issued: March 05, 2013
  • Status: Active
Military Technology

Bombs lined with reactive liners that improve the blast and fragmentation of the bombs is disclosed. The effect is caused by the Richtmyer-Meshkov instability which is introduced at the explosive/reactive liner interface by introducing semi-cylindrical open linear cells between the reactive liner and the explosive that are void. This geometry produces a turbulent flow effect which readily mixes the reactive liner when accelerated by the grazing shock wave generated during detonation, which moves through the liner and case material. The geometry produces the added effect of creating faster and more plentiful fragments that are lighter in mass than those produced by typical bombs that are annularly lined with reactive liners, while maintaining insensitive munitions capability.
