FIELD: ammunitions. SUBSTANCE: invention refers to ammunition, specifically, to artillery cases and can find use in production of composite artillery cases of large caliber with plastic body. Composite artillery case is composed of body, tray with threaded nipple and nut put on it. Bottom part of body passes over radius into side wall of body has outer radius corresponding to radius of bottom part. Flat rubber spacer is positioned between outer surface of tray and rigid metal spacer put freely on nipple and resting with its side surface against inner surface of body. Body is formed as one unit from polyethylene. Nut has opposite flats. Case is provided in addition with at least one rigid flat ring metal spacer which outer diameter is less than outer diameter of present spacer and which is placed directly under nut on present spacer. Characteristic feature of assembly of case consists in mating of body with tray over radius followed by drawing up to tray nut put on threaded part of nipple. Ring flat rubber spacer is positioned before mating of body with tray. Spacer made of metal is freely put on nipple and additional spacer is placed on it in case of necessity. Drawing of nut is carried out by torque 30.0 ± 4.0 kg.m. EFFECT: simplified process of assembly, its decreased time. 3 cl, 2 dwg
