Abstract

This research aims to analyze the literature on nano-composite-based energetic materials that can be used in hybrid propellants for military rockets. Hybrid propellants, which combine the properties of liquid and solid propellants, offer advantages such as improved combustion control and higher energy efficiency. In this context, nano-composite materials, such as metal nanoparticles (aluminum, boron) combined with oxidizers and polymer fuels, have great potential to improve the performance of hybrid propellants. This literature review identifies how the unique properties of nano-composites, such as large surface area, high reactivity, and the ability to control particle distribution, can accelerate the combustion rate and result in higher thrust. In addition, technical challenges such as controlling nanoparticle agglomeration, thermal stability, and environmental issues are discussed. This research provides an in-depth understanding of the application of nano-composite technology in the development of hybrid propellants and demonstrates the potential of these materials to improve the performance and safety of military rocket propellants. The findings are expected to serve as a basis for further research and development of more efficient hybrid propellants in the defense field.

Abstract

PT Pindad, a prominent defense industry leader in Indonesia, is renowned for its high-quality, small-caliber munitions, contributing significantly to the achievements of the Indonesian National Army both nationally and internationally. In the face of globalization and the imperative for robust national defense capabilities, self-sufficiency in munitions production and development is crucial. PT Pindad has been at the forefront of munitions innovation, particularly in addressing challenges related to the supply of propellant materials. This study uses a Feasibility Study approach to explore the innovative use of waste paper as a raw material in producing nitrocellulose (NC) and nitroglycerine (NG). Given NG's sensitivity and volatility, diethylene glycol dinitrate (DEGDN) is proposed as an alternative component in developing an efficient and reliable NC-DEGDN propellant blend. This research supports the strategic goal of advancing Indonesia's munitions independence. Keywords: Defense Industry, Propellant Innovation, Munitions Development, Sustainable Materials

Abstract

Indonesia, as the largest archipelagic country in the world with a strategic geographical position, has an urgent need to develop a reliable defence system, one of which is through rocket technology. The RX-70 rocket is one of the national rocket development programs designed to strengthen domestic defence capabilities. This study aims to analyze the thrust performance of the RX-70 rocket motor with a numerical simulation approach using BurnSim software. The main focus of this study is to evaluate the effect of variations in Cyclotrimethylenetrinitramine (RDX) content and star grain geometry configuration on the combustion characteristics and thrust performance of a rocket based on composite propellant containing Ammonium Perchlorate (AP), Aluminium (Al), and HTPB binder. The study was conducted quantitatively using simulations based on optimized propellant formulation data using ProPEP software. Variations in the number of star grains analyzed included configurations of 3 to 9 star points, with RDX content varying from 0% to 20% by weight. The simulation results showed that increasing the number of star grains contributed significantly to increasing the combustion surface area, which had a direct impact on increasing maximum thrust and reducing burn time. This shows that grain geometry has a dominant influence on motor performance compared to variations in RDX content in the tested range. On the other hand, the addition of RDX did not significantly increase thrust, but had an impact on combustion efficiency and the formation of condensed combustion products (CCPs). Higher RDX content tends to produce greater agglomeration of aluminium particles, which has an impact on decreasing combustion efficiency. The Star 8 configuration with the fifth variation showed the best performance, with the highest combustion chamber pressure reaching 753 psi and a stable thrust above 2,090 N. These findings emphasize the importance of grain geometry optimization in rocket motor design, as well as the need for a balance between energetic material content and combustion efficiency. This research contributes to the development of composite propellant design for national defence applications. To strengthen the validity of the findings, full-scale experimental testing is recommended to compare simulation results with actual performance in the field.
