Abstract. The paper presents the activities of the Polska Grupa Zbrojeniowa (Polish Armaments Group) (PGZ) in the area of research and development in the process of modernizing the Polish Armed Forces aimed at reconstructing the Polish defence potential and strengthening the potential of Polish science and defence industry. Priorities of the development of the Polish Armed Forces are discussed along with trends in technology and areas of activities of PGZ as the consolidating unit of the defence industry companies. Keywords: PGZ Group, research and development activities

Abstract. The article presents a new profession in the labour market: the Project Manager. Formal requirements and personal features of a project manager are discussed. Organizational transformations and training processes conducted at OBRUM in order to adapt to new organizational structures (Polish Armaments Group) and based on project management methodology are presented. The benefits of the project management system implemented at OBRUM are also reviewed.

Abstract. The paper presents a new form of management - project management - implemented at OBRUM. The adopted PRINCE2 and PMI methodologies are discussed along with the implemented reporting lines. The benefits obtained and future development trends in project management are described, including IT support.

Abstract. The article describes deployment of an IT tool in OBRUM sp. z o.o. – Microsoft Enterprise Management platform. Previously existing needs for centralized access to project data were named together with the description of new tool’s functionalities and supported areas. Finally, benefits of the deployment were pictured compared to the initial situation.

Abstract. The paper discusses an innovative design of a tracked vehicle with hybrid drive being implemented by a research consortium. A short review of land platform of dual use, civilian and military, is presented. The position of the design discussed among other land platforms is shown. Design requirements, purpose of the work and adopted design methodology are discussed along with the creation stage and final outcome. The summary includes a reference to the developed design version and practical implementation in the form of a technology demonstrator and to further development of the project.

Abstract. The paper presents problems associated with proper design of an electrical system of a vehicle with a hybrid propulsion system (internal combustion + electric). Topology of the system is shown along with results obtained: tables of parameters of a high current electrical system of a hybrid vehicle. The paper describes major components of the design work, including power balance, safeguards, wire cross sections, determination of the working point of a fan and soft start system for the electric motor. In conclusion, reference is made to the practical application of the calculation results.

Abstract. The article presents an overview of the results of studies carried out at the Institute of Non-Ferrous Metals, Light Metals Division (OML IMN). The aim of the studies was to develop a design of passive armours and a technology for their manufacture. The results of studies of panels produced by two different manufacturing techniques are presented. The first manufacturing technique is permanent mould casting; the second consists in bonding of individual layers with adhesives and lamination using chemically or thermally cured epoxy resins. For both technologies, tests were made to check the applicability and behaviour of light metal alloys in passive armours. The tests under fire of passive armour models have demonstrated the usefulness of both technologies and the applicability of light metals. For different variants, an effective stopping of B-32 bullets calibre 7.62 mm and 12.7 mm was achieved

Abstract. Experimental studies described in the present article adapt modern VSC 500 equipment produced by UBE for the squeeze casting technology, located at Foundry Research Institute in Cracow, Poland. The aim of such adaptation was to set up a comprehensive technology capable to manufacture essential elements for lightweight composite armour protection. The overall scope of the study included development of basic design of an armour element and the selection of materials necessary for its construction. Furthermore development of special mould design along with determining the optimal parameters for the squeeze casting process has been considered. The presented unique liquid-phase technology of composite element manufacture allows obtaining armour elements with a high protection efficacy against small-calibre armour piercing projectiles. The elements can also be part of a modular protection system for mobile transport means (land and aerial vehicles).

Abstract. The paper discusses the basic features of a stand developed for gunfire-testing of armour plating samples. Reference is made to the results of research carried out at the Research Department of the Zakłady Mechaniczne Tarnów S.A. Conclusions include prospects for further development of the design.
