Reaction kinetics are determined using differential scanning calorimetry (DSC) and thermogravimetric (TGA) experiments. In addition, small cook-off tests are completed to assess both the reaction temperature and exothermic behavior of the material when subject to a ramped heating rate of 3.3°C/h. Based on experimental observation, two heuristic reaction schemes are derived. These mechanisms are implemented into a 3-D, fully transient, hydrocode and parameterized by direct comparison with the subscale cook-off test results. This model simulates the heat transfer into a propellant grain as well as the heat generated by the reaction, and is used to assess the experimentally determined global reactions. A comparison of the reaction kinetics, the techniques used to obtain them, and their applicability to slow cook-off of a composite propellant is presented. %8 2015-03-17
