Topic Thermolysis Studies and Reaction Mechanism Development for High Energy Density Energetic Materials
From 2015
To 2018
Budget 20 lacs
Details The project involves pyrolysis studies of high energy materials which are potential replacements for existing propellants in space and defense applications. The materials will be subjected to FTIR, TGA and DSC diagnostic techniques to study their decomposition. These techniques will give information about the species formed on decomposition, the mass loss rate and the differential heat release rate with time. The data thus obtained will be used to formulate a chemical reaction mechanism for the energetic materials. This mechanism will be validated by employing quantum mechanics based computations to obtain optimized molecular structures, reaction path details and kinetic parameters of individual reactions.

Topic Combustion Analysis of Ammonium Perchlorate Based Propellants using Detailed Chemical Kinetics
From 2017
To 2020
Budget 30 lacs
Details Ammonium perchlorate (AP) has been widely used in the propellant industry during the last few decades. It is preferred in propellant applications because it is a strong oxidizer, easily available and compatible with other solid propellant components. Researchers always seek the ability to predict the performance of composite propellants which have AP as an ingredient by carrying out numerical simulation of combustion phenomena such as strand burning. They also pursue the skill of being able to forecast the behaviour of AP in various propellant mixtures under thermal stress during storage and handling. For achieving these objectives, it becomes necessary to possess proper knowledge of the thermal decomposition processes involving AP and the corresponding kinetic parameters. Hence the aim of this project is to carry out a detailed investigation of the AP decomposition processes using state of the art experimental and computational tools. This would add to the already existing knowledge and result in the development of a detailed chemical kinetics mechanism (DCKM) for AP decomposition under various conditions. This DCKM can then be used as input to improve the predictive capability of numerical models and thus fulfil the above mentioned objectives. Elucidation of the overall decomposition chemistry for AP to get the DCKM is challenging because of the possibility of completely different chemical reactions and processes being active under different conditions. Hence separate experiments need to be carried out to analyse the two domains of decomposition (i) rapid combustion in propellant applications and (ii) slow degradation during handling and storage. The experimental tools that are proposed to be used are thermogravimetric analysis, pyroprobe, Fourier transform infrared spectroscopy, high-pressure differential scanning calorimetry and mass spectrometry. In the light of experimental results thus obtained, a chemical reaction scheme containing reaction rate parameters of individual elementary reactions will be formulated with the use of quantum mechanics based computations. These computations involve optimization of ground state and transition state molecular structures and reaction path calculations. Components such as hydroxyl terminated polybutadiene (HTPB) in the AP based propellant mixture being considered also need to be subjected to similar experimental and computational investigation as elaborated above. The results obtained on successful execution of this project will provide a better understanding of the behaviour of propellant ingredients and thus help in improving existing propellants as well as in developing new propellant compositions.
