摘要： A multi-layer propellant and a method for making the same is provided, in ich the propellant has at least one slow burning formulation and at least one fast burning formulation, such that the ratio of these burning rates is at least 2:1. The propellant produces an impetus of at least 1300 Joules/gm. The preferred binder is a high energy oxetane thermoplastic elastomer. The preferred slow burning formulation employs RDX, while the preferred fast burning formulation employs CL-20. The two formulations are formed separately, such as in layers that are then fused, using the bonding strength of the binder. The shape may be any shape that is useful in munitions and may include one or many layers of each burning rate. Preferred shapes include a multi-layered propellant with one slow burning formulation on top and a bottom layer of the fast burning formulation. The layers may be formed from ribbons, discs, cones, truncated cones and partial spheres. The amount of binder in each formulation should be sufficient to provide a uniformly dispersed oxidizer throughout the layer. Preferred amounts of binder range from about five percent to about thirty percent by weight, based on the total weight of the propellant.

摘要： Methods of making cross sectional, functionally-graded munitions propellants exhibiting various distributions of particle concentrations and burn rate, including having a fast burning core and slower burning outer layer(s). Unlike prior art methods of preparing such munitions, propellants prepared according to our inventive method(s) may be performed substantially as a single extrusion step or as a few processing steps, without requiring the time, expense and/or difficulties that characterized familiar, laminating methods and methods which use multiple extruders. Our inventive method advantageously employs a demixing phenomenon that, prior to our inventive application and teaching, has been considered quite undesirable in the preparation of propellants where uniformity and well-mixedness have been propellant attributes widely sought after.

摘要： A high energy propellant, comprising an oxetane thermoplastic elastomer energetic binder admixed with a high energy explosive filler. The oxetane thermoplastic elastomer energetic binder preferably comprises from about five percent to about thirty percent by weight and the high energy explosive filler comprises from about seventy percent to about ninety-five percent by weight of the composition. A preferred propellant further includes an explosive plasticizer, preferably in an amount of about four percent to about seven percent of the plasticizer by weight of the propellant. The preferred filler is selected from the group consisting of CL-20, TNAZ, RDX and mixtures thereof. The preferred plasticizer is selected from the group consisting of TNAZ, BTTN, TMETN, TEGDN, BDNPA/F, methyl NENA, ethyl NENA and mixtures thereof. In a preferred embodiment, the propellant is actually a pair of high energy propellants comprising a mixture of first and second high energy propellants with the first propellant having a burning rate at least two 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 elastomer energetic binder admixed with RDX high energy explosive filter. Plasticizers and relative amounts for each of the first and second propellants are the same as for the single propellant.
