Abstract : An adiabatic, self-heating apparatus was assembled for determining the kinetic parameters of the propellant decomposition process, for purposes of predicting critical diameter, at a given temperature; or time to deflagration for various regular shapes, at a given temperature in storage. A modified Parr bomb was used to contain the test sample, providing for constantvolume operation, with the decomposition products constrained to remain in the vicinity of the propellant grain. The activation energy and heat generation coefficient were determined for a typical composite Nitrocellulose-base propellant. The results obtained here indicate that this apparatus is appropriate to the study of the kinetic par meters in solid propellant decomposition. (Author)
