NUMERICAL STUDY OF THE RESPONSE OF THE BODY OF A HEAVY VEHICLE TO AN IMPACT LOAD AS EXEMPLIFIED BY THE KRAB SELF-PROPELLED GUN-HOWITZER / WIESŁAW BARNAT
Abstract. The paper presents results of numerical analyses of the response of the body of a gun-howitzer to gun shot in different positions of the gun in relation to the body. Shots at several different barrel elevation angles were analyzed, including the worst cases in terms of structure strength. Numerical analysis was performed using the explicit method of computing fast-changing phenomena. The adopted main criterion of body response assessment was material effort.
CONVERSION OF THE T-72 TANK. NEW LINK IN THE PRODUCT LIFECYCLE / MONIKA KURPAS, MARIAN HOLOTA
Abstract. The paper presents a proposal to convert decommissioned weapons to be reused in different versions of engineering vehicles illustrated with the example of the T-72 tank. The solutions presented illustrate the possibilities of constructing new tracked vehicles of various use at relatively low cost. The proposed methodology may be used as a commercial offer of the Polska Grupa Zbrojeniowa (Polish Armaments Group) (PGZ) in the form of know-how (upgrade packages) or deliveries of complete vehicles of various use, particularly to countries that have T-72 tanks in service.
MODULAR DRIVE SYSTEMS / BARTOSZ STACHURA
Abstract. This article describes some of the modern drive systems primarily designed for use in military technology. The main features of the power-pack type systems are discussed along with their structure. The most important technical parameters are listed on the basis of selected examples of Polish applications. In addition, tables are provided with known examples of implemented applications of modular drive systems in land vehicles: armoured personnel carriers and tanks.
CONCEPT OF A NEW ASSAULT BRIDGE / JANUSZ ŚLIWIŃSKI, ZBIGNIEW KAMYK, WACŁAW MALEJ, JANUSZ ŚLIWIŃSKI
Abstract. The article discusses the design of modern assault bridges used in military operations to cross anti-tank trenches and other such terrain obstacles. Usefulness of such bridges in military operations is illustrated with the example of US operations in the Persian Gulf. Possible applications of carbon-fibre composite materials in aluminium bridge construction are presented. The article presents a concept of an assault bridge for quick negotiation of anti-tank trenches.
STUDY OF THE MECHANICAL PROPERTIES OF THE MS-40 BRIDGE SPAN / ZBIGNIEW RACZYŃSKI
Abstract. The paper presents selected results of strength tests of the MS-40 bridge span. The tests included static loading of the bridge as specified by the standard for MLC 70 (T) class – tracked vehicles – and MLC 110 (W) class – wheeled vehicles. Stresses in selected points of the main and auxiliary spans of the bridge were recorded during the tests.
TESTS OF SCISSORS-TYPE BRIDGE STABILITY / ZBIGNIEW KAMYK, WACŁAW MALEJ, CEZARY ŚLIWIŃSKI, MARCIN DUSZAK, JANUSZ ŚLIWIŃSKI
Abstract. The paper presents functional classification of military bridges with respect to different phases of combat operations. Individual phases of positioning the bridge span over a gap are described, with particular attention paid to maintaining longitudinal and transverse stability. A method of determining the longitudinal stability margin and the additional overturning moment for the MG-20 bridge span is described. This moment results from the systems’ inertia in the case of bridge span emergency stop during bridge launching. A method of verifying the longitudinal and transverse stability of the MS-20 bridge span in vertical position under windy conditions is also described. The analyses have demonstrated proper stability of both the MS-20 and MG-20 bridge spans.
BATTLEFIELD SIMULATION SYSTEM GIEWONT / JANUSZ ZEMBACZYŃSKI
Abstract. The GIEWONT battlefield simulation system is a modern tool for conducting training at all levels in the Land Forces and Special Forces, as well as in other branches of Armed Forces. The modules of this system allow to conduct individual shooting training, as well as performing tactical exercises of platoon, company and battalion, or to engage in simulated battles in urban areas. The article discusses the most important tactical and technical parameters and capabilities of the system.
