Monolithic nitrocellulose and cellulose (NC-C) composites solidified with starch were used in a model reactive armour with steel plates. The acceleration ability of the gaseous reaction products of composites was examined by the use of X-ray technique. The effectiveness of the reactive armour containing NC-C composites in weakening the ability of jet penetration was assessed experimentally on the basis of the size of holes in the steel plates and effects of the impact of jet particles on a steel plate located under the armour. It has been shown that the size of the holes in the driven plate increases and the degree of penetration of the “witness” plate is reduced with the decrease of the angle of jet impact. The modified Gurney model was applied to simulate the process of driving steel plates in the reactive armor with a layer of NC-C composite. The model was verified by using the results of X-ray recording of plates driven by the reaction products. The effectiveness of reactive armors with NC-C composites in weakening the penetration ability of shaped charge jets was evaluated in a manner based on the results of theoretical modeling
