Definitions

  • This invention relates to a bomb and in particular to a novel explosive filling and method of filling a bomb.
  • the method used to determine these terminal effects is that of bomb size and explosive capacity.
  • Modern bombs display certain insensitivities to external stimuli such as fire, slow heating, bullet or fragment attack.
  • air-dropped bombs are difficult to protect against the effects of Sympathetic Detonation where one bomb exploding in close proximity to another would also detonate the adjacent bomb or bombs.
  • the present invention stems from our appreciation that there may be ways in which new or existing bombs may be filled from new, or in retrospect, in a way that produces reduced terminal effects and hence lower collateral damage.
  • a bomb explosive filling comprising a charge of explosive and a charge of an inert material.
  • the effect of incorporating inert material can be pre-determined through modelling and trials before bomb filling takes place.
  • the present invention can provide increased safety from the effects of Sympathetic Detonation by the use of relatively insensitive explosive fillings. This can be further improved by arranging the charge of an inert material radially external to the charge of explosive material, thereby increasing the separation distance between live explosive fills in adjacent bomb by virtue of the inert filling surrounding them.
  • the invention enables a variable of 'tuned' fill to be achieved.
  • variable or "tuned" fill is achieved in two stages at bomb filling by:
  • Modern explosive fills may consist of Polymer Bonded Explosives having an inert polymer base with the explosive mixed in.
  • the mass, poring and setting properties of the inert polymer does not differ significantly from that of the mixed polymer/explosive and therefore provides an exceptionally stable inert filling for the first stage of the filling process.
  • Other inert materials may be used given the need to prevent any adverse chemical or physical reaction with the bomb case or the live explosive fill.
  • Certain lining materials may be used between the bomb case and the inert filing and between the inert filling and the live filling in order to provide specific protection from any possible interaction of the components.
  • This invention can be used for filling new bombs and for re-filling old bombs that have had their previous explosive fill removed.
