Diesel fuel compositions that are extremely stable against thermal degradation, sedimentation and discolouration arc devoid or essentially devoid of certain heteroatomic compounds often present in diesel fuel and which have been discovered to cause the thermal degradation in the presence of nitrate-based cetane improver additives. The specific deleterious heteroatomic compounds include pyrroles, indoles, sulfides, disulfides, mercaptans, thioacids, sulfonic acids, and indolines.
The invention relates to Insensitive Munition (IM) energetic materials particularly non- phthalate IM propellant compositions.
An energetic composition suitable for use as a propellant comprises the following components in the following relative proportions:
component A; from 60% to 90% by weight of a highly energetic filler comprising at least one nitramine compound; and
component B: from 5% to 20% by weight of a binder,
component C: from and 3% to 15% of a plasticiser wherein the plasticiser comprises formula (A)
of from 1% to 9% by weight, wherein Formula (A) is a diester plasticiser of
R1-OC(O)-R3-C(O)O-R2, Formula (A)
wherein R1, R2, and R3 are independently selected from C3 to C10 alkyl or alkenyl.
the percentages by weight of components A, B and C, together with minor additives, if any, adding to 100%.
本发明涉及不敏感弹药(IM)能量材料,特别是非邻苯二甲酸盐 IM 推进剂组合物。
适合用作推进剂的高能组合物包括以下相对比例的组分:
A 组分;按重量计,60%至 90%的高能填料,包括至少一种硝胺化合物;以及
B 组分:5%至 20%(按重量计)的粘合剂、
