Definitions

  • the present invention relates generally to a ihigh energy propellant composition. More particularly the invention relates to a propellant that includes an energetic thermoplastic elastomer as a binder and a high energy, high density filler. I ,
  • one object of the present invention is to provide a pair of high energy propellants whose average impetus is at or above the 1300 J/g level.
  • Another object of this invention is to provide a pair of high energy propellants whose burning rate differential is three or greater.
  • An additional object of this invention is to provide new energetic materials and processes that eliminate or greatly reduce both volatile organic compound production and ancillary waste through demil and recyclability.

  • a pair of high energy propellants may be combined to produce a propellant mixture having a first propellant having a burning rate at least three times faster than the burning rate of the second propellant.
  • the first propellant includes an oxetane thermoplastic elastomer energetic binder admixed with CL-20 high energy explosive filler.
  • the second propellant including an oxetane thermoplastic
  • the ratio of burning rates may I be varied from at least 2.0 times to as high as 4.8 times, or higher ⁇

  • steps of mixing at about 95 °C and extruding at slightly lower temperatures Processing at these temperatures provided a safe operating margin of at least 50 ° C because the self heat temperatures of the filler ranges from about 175 °C to 192 °C, but the preferred plasticizer TNAZ melts around 100 °C, so that as some of the TNAZ begins to melt during processing at 95 °C, a more fluid mix results that is easier to process.

Abstract

Agent propulsif à haute énergie contenant un liant énergétique élastomère thermoplastique d'oxétane, mélangé à une charge explosive à haute énergie. Le liant énergétique élastomère thermoplastique d'oxétane constitue, de préférence, environ 5 à 30 % en poids de la composition et la charge explosive à haute énergie constitue environ 70 à 95 % en poids de la composition. Un agent propulsif préféré comprend également un plastifiant explosif, de préférence à raison d'environ 4 à 7 %. La charge préférée est choisie dans le groupe constitué de CL-20, TNAZ, RDX et de mélanges de ceux-ci. Le plastifiant préféré est choisi dans le groupe constitué de TNAZ, BTTN, TMETN, TEGDN, BDNPA/F, NENA méthylique, NENA éthylique et des mélanges de ceux-ci. Dans un mode de réalisation préféré, l'agent propulsif est constitué de deux agents propulsifs à haute énergie, comprenant un mélange d'un premier et d'un second agent propulsif à haute énergie, le premier agent ayant une vitesse de combustion au moins deux fois supérieure à celle du second agent. Le premier agent propulsif comporte un liant énergétique élastomère thermoplastique d'oxétane, mélangé à une charge explosive à haute énergie de CL-20. Le second agent propulsif comprend un liant énergétique élastomère thermoplastique d'oxétane, mélangé à une charge explosive à haute énergie de RDX. Les plastifiants et les quantités relatives pour les premier et second agents propulsifs sont les mêmes que lorsqu'un seul que pour un seul agent propulsif.
