This paper investigates chemical and thermal stability of flexible PBX's during their artificial ageing in term of their similar plastic binder. It was documented, they contain the rubber NBR and the similar base (RDX, PETN or RDX with PETN), but they don't have equivalent behaviour during the artificial ageing. It was discovered one from them is chemically unstable, because probably the rubber NBR is incompatible with RDX.

In this paper is compared computer modelling of the fragmentation warhead effects in dependence of variety high explosives with practical test results. For the fragmentation modelling was used analytical code SPLI-X version 3.02. SPLIT-X is an expert system for the design of fragmentation warheads. The influence of next high explosives on fragmentatio effect was compared: cast trinitrotoluene (TNT), mixture explosives TNT/RDX/wax and insensitive HE type of the plastic bonded explosives (PBX) NTO/RDX/IB (IHE).

This elaboration investigates how does the marking agent influence the stability of plastic explosives. It makes a judgement of both chemical and thermal stability of the marked high explosives over a last few years was relating to their composition and along with it compares their stability with the pure explosives, which is the marked explosives base.

In this paper is compared the fragmentation effect of 100 mm HE warhead in the dependence of variety explosives. For the tests were used: cast trinitrotoluene (TNT), mixture explosives TNT/RDX/wax 47,5/50/2,5%, TNT/RDX/wax 40/59/1% (Composition B), TNT/RDX/Al/wax 40/42/15/3% and insensitive HE type of the plastic bonded explosives (PBX) NTO/RDX/IB45/38/17%.

EN
The basic informations about the principle loading HE into artillery projectile by screw less extruder, development of insensitive high explosive suitable for loading by screw less extruder and the results of the tests loadings artillery 100 mm HE projectiles are described in this paper.
