Monolithic nitrocellulose and cellulose composites (NC-C) were obtained by cross-linking a mixture of nitrocellulose with cellulose using hexamethylene diisocyanate (HDI). They were incorporated into a model reactive armour. An X-ray technique was used to examine the infuence of the cellulose content on the accelerating ability of the gaseous reaction products of the composites. The modifed Gurney model was used to simulate the process of driving steel plates in the reactive armour after jet impact. Formulae for the determination of the time-space characteristics of the plates’ movement were derived. The results of the X-ray recording of the plates driven by the explosion products of monolithic nitrocellulose and cellulose composites (NC-C) were used for the verifcation of the model.
