The design of complex armament details is a challenging process that requires great amount of time and data collected from ballistic calculation of the artillery tube. The developed software product that calculates the recoil brake’s piston rod replaces the large amount of computational work required, reduces the probability of calculation errors and enables the designer to focus his creative thinking into the combination of different materials and construction dimensions. The ability to export the calculated piston rod profile afterwards allows for easy transfer of the information required into a 3D virtual reality and the use of 3D modeling for the construction of the piston rod and the recoil braking device.

Today’s battlefield is ever-changing in terms of weaponry demands and engagement criteria. Older artillery ordnance is often struggling to meet the modern battlefield demands and does not provide the operator with a wide range of capabilities. This combination of constraints coupled with the performance of conventional artillery munitions has often limited the commander’s options and decreased the effectiveness of artillery. Meeting the modern battlefield demands requires the performance and capabilities of existing ordnance to be increased. This paper researches the creation of a smart fuze that will provide increased flexibility and capabilities at a price that permits its use in tactically significant quantities as well as for training.

Today’s battlefield is ever-changing in terms of weaponry demands and engagement criteria. Demands for additional capabilities of current ordnance are constantly growing. An easy yet cheap and effective way to increase existing and also add additional capabilities of current ordnance is by introducing a smart fuze that incorporates electronic components. In this report, a smart fuze software algorithm is created that is customizable, gathers and analyzes data from different sensors and provides different fuze functions. Introducing, as well as, upgrading existing fuze functions making them precise and accurate.

Virtual prototypes or virtual 3D models of complex armament parts reduce costs and production time with minimal risk of hidden flaws, testing and analyzing the construction before creating real physical prototypes or optimizing parameters in parallel with the physical prototypes. The report presents the possibility of rapid prototyping through the virtual 3D model of the SPG-9 breech and using additive manufacturing to obtain a functioning physical prototype.

Part of the global trends related with the development of armaments are currently focused on creating new samples of small arms and device which have increased combat effectiveness.

Two of the factors that have a significant impact on combat effectiveness are grouping and accuracy in shooting. Installation of the silencer on small arms leads to a change of these factors, especially when must be shoot at long distances.

The report scrutinizes an experimental investigation on the mathematical ratio of hit point on the target at shooting with small arms with fitted silencer of the chamber type with rubber chopper wheel.

Currently terrorism is one of the biggest threats for the security on national and international level. The increase of the terrorist activities led to the expansion of tasks performed by the Armed Forces. In a significant part of cases due to the specificity of the anti-terrorist activity the sound of the shots should be hidden. This can be achieved by using special devices called suppressors. That require determine of target area limits which is the purpose of that report.
