Review of the Problems of Additive Manufacturing of Nanostructured High-Energy Materials

This article dwells upon the additive manufacturing of high-energy materials (HEM) with regards to the problems of this technology’s development. This work is aimed at identifying and describing the main problems currently arising in the use of AM for nanostructured high-energy materials and gives an idea of the valuable opportunities that it provides in the hope of promoting further development in this area. Original approaches are proposed for solving one of the main problems in the production of nanostructured HEM—safety and viscosity reduction of the polymer-nanopowder system. Studies have shown an almost complete degree of deagglomeration of microencapsulated aluminum powders. Such powders have the potential to create new systems for safe 3D printing using high-energy materials.

Effect of boron on HEM radiant ignition characteristics

The paper presents the ignition characteristics of high-energy materials (HEMs) containing ammonium perchlorate, butadiene rubber, and a mixture of Al/B nanopowders with different component ratios. Bimetallic systems based on aluminum with boron increase the reactivity and intensify the ignition of boron particles, which helps to decrease the critical ignition conditions of HEMs during heating. It is shown that the use of systems based on aluminum-boron reduces the delay time (by 17–52 %) and the ignition temperature of propellants in comparison with a HEM containing aluminum powder, and increases the activation energy of HEM during radiant heating.

INFORMATION-MEASURING SYSTEM OF STRENGTH TESTS AT THE STAGE OF STAND TESTS OF PRODUCTS FROM HIGH-ENERGY MATERIALS

Рассматривается разработанная на АО «ФНПЦ «Алтай» информационно-измерительная система (ИИС), предназначенная для автоматизации сбора и обработки результатов измерений при стендовых испытаниях изделий из высокоэнергетических материалов. Ее основной задачей является многоканальный сбор данных о результатах стендовых испытаний, обработка, документирование и хранение результатов измерений. Показано, что в процессе разработки, производства, доводки и серийного выпуска изделий из высокоэнергетических материалов особо важными являются прочностные испытания, позволяющие оценить работоспособность и технические характеристики, а также сроки хранения и эксплуатации. The paper considers the information and measuring system (IMS) developed at the Altai Federal Research and Production Center JSC, designed to automate the collection and processing of measurement results during bench tests of products made of high-energymaterials. Its main task is multichannel collection of data on the results of bench tests, processing, documentation and storage of measurement results. It is shown that in the process of development, production, fine-tuning and serial production of products made of high-energy materials, strength tests are especially important, which make it possible to assess the performance and technical characteristics, as well as the storage and operation periods.
