摘要： The present application is directed at a thermoplastic filament for use in three-dimensional printing processes for the manufacture of energetic objects which can be used for propulsion of projectiles in weapons and for solid rocket engines. The thermoplastic filament comprises at least one energetic plasticizer and nitrocellulose, wherein the ratio of the concentration of the at least one energetic plasticizer to the concentration of the nitrocellulose is between 0.5:1 to 2:1 by weight. The present application is also directed at the use of such a thermoplastic filament in a three-dimensional printing process, preferably in a material extrusion type three- dimensional printing process, to the manufacture of energetic objects which can be used for propulsion of projectiles in weapons and for solid rocket engines.

摘要： Die vorliegende Anmeldung betrifft ein Treibladungssystem zum Verschiessen von Artilleriegeschossen mit mindestens zwei Teilladungen. Die Teilladungen weisen je einen Pulvertyp auf, der Nitrocellulose, mindestens einen kristallinen Energieträger sowie mindestens einen ersten inerten Weichmacher umfassen. Mindestens eine Teilladung weist einen ersten Pulvertyp und die mindestens eine weitere Teilladung einen zweiten Pulvertyp auf. Der zweite Pulvertyp weist im Bereich von oberflächennahen Zonen auf eine Eindringtiefe von maximal 400 Mikrometern zwischen 2 bis 10 Gewichtsprozent eines zweiten inerten Weichmachers auf, während der erste Pulvertyp in oberflächennahen Zonen keinen zweiten inerten Weichmacher aufweist.

摘要： The propulsion system for the acceleration of projectiles is based on a multi-perforated grain propellant and is composed from nitrocellulose, a crystalline energy carrier of a nitramine type and an inert plasticizing additive. The number of perforations is 2 to 6, preferably 4. The propellant grains can have round or polygonic profiles, depending on the number of perforations. The preferred grain geometry is cubic with a rectangular grain profile. The nitramine compound contains a structural element of the general chemical structure formula R-N-N02, where R is a residual group. The nitramine compound is present in a concentration in the range from 0 to 35% by mass, in particular in the range from 5 to 25% by mass. The nitramine compound is preferably RDX. The inert plasticizing additive is a water-insoluble polyoxo compound, if necessary in combination with a substance containing carboxyl groups. In layers near the surface an increased concentration can be present. The inert plasticizing additive is present in a concentration of 0 to 10% by mass, preferred 0 to 5% by mass.
摘要翻译：用于加速射弹的推进系统基于多孔颗粒推进剂，由硝化纤维素，硝胺型结晶能载体和惰性塑化添加剂组成。穿孔的数量为2至6，优选4.推进剂颗粒可以具有圆形或多角形轮廓，这取决于穿孔的数量。优选的晶粒几何形状是具有矩形晶粒轮廓的立方体。硝胺化合物含有一般化学结构式R-N-N02的结构元素，其中R是残基。硝胺化合物的浓度范围为0〜35质量％，特别是5〜25质量％。硝胺化合物优选为RDX。惰性增塑添加剂是一种不溶于水的聚氧化合物，如果需要与含有羧基的物质结合使用。在靠近表面的层中，可以存在增加的浓度。惰性增塑添加剂的浓度为0〜10质量％，优选为0〜5质量％。
