This paper shows preliminary numerical analysis of impact of IED sidebar blast on the hull of the light fighting vehicle in order to meet the current standards. Numerical analysis was carried out using a 3-dimensional shell FE model of the vehicle. The problem of the modelling method and computer simulations required several specific features for applied material models, e.g. physical state, plasticity, crispness, hardness. All necessary material properties were taken from the available literature or they were based on the experimental tests carried out in the Department of Mechanics and Applied Computer Science at the Military University of Technology. The STANAG 4569 is a legal basis that regulates the level of ballistic protection for such vehicles. Companies producing that kind of armoured vehicles for army, constantly look for the best and the newest energy consuming materials to ensure appropriate protection of the vehicle and the crew inside it against the effect of IED blast. The connection between a detonation wave and a formed shrapnel shell after detonation of the IED is created depending on the mass and kind of the charge. It is caused by impulsive load on a side bar or the bottom of a light vehicle. Both, safety of people and equipment endurance, is compatible with main rules that are common in Polish Army and it will be common rule in future. It is the fact that motivates the research centres and the arms industry to develop a product using advance computation method to construct new energy absorbing construction which will increase safety of the crew in the armed vehicle.

The paper presents experimental static tests of IED interrogation arm for Shiba special vehicle. The test was performed by Military University of Technology and Military Institute of Engineer Technology. A number of strain gauges and camera markers were placed on the arm to allow recording strains and movements of specific construction points. The arm's motion was recorded using high speed camera. The equipment used were Vishay EA 06 120LZ 120 strain gauges with ESAM Traveller bridge. The sampling rate was 1000 Hz. The test was to pick up maximum design weight, move it to maximum overhang and then drop it on the ground. During the test, signal from gauges and video capture was recorded. The data was then processed using Thema 3D software to obtain markers displacements and angular changes of both arm parts. Afterwards, the test was repeated for different weight. The analysis showed, that maximum stresses in examined construction parts did not exceed yield stress of material. As well as that, in-depth motion analysis of the arm was conducted. Further works are twofold. Firstly, there will be tests concerning arm under dynamic load occurring during normal maintenance During this test only strains in specific construction parts will be recorded. Secondly, numerical model of an arm will be developed and validated using data obtained during both tests. This will help visualize stress distribution in each arm's part.

More and more impudent attacks on the military convoys in Afghanistan proved a huge danger of the improvised explosive devices - IED. Huger and more clever charges are a serious problem for vehicles protection. Additionally, hitherto defence standards and STANAG didn't predict such huge charges. Majority investigations were based on a 3 kg anti-tank mine. The article presents the results of numerical calculations for the elements of the combat vehicle supporting structure loaded with an impact generated by explosion of a huge explosive charge under the bottom of the vehicle with consideration of the wave reflected from the ground. Such an approach allows obtaining a good approximation of numerical simulations to real conditions of terroristic attacks. Additionally, the analysis of IED side influence on the vehicle shell was conducted. The explosive charge — IED — was simulated with the use of concentrated energy of properly selected (on the base of literature investigations) density and initial energy. During analyses of side explosive on the vehicle structure, the obstacle in the form of a building increasing the pressure impulse was taken into account. The paper presents the results of a numerical analysis in which Euler and Lagrange domains(describing a vehicle) were coupled. A perfect gas model was used to describe air parameters.. Additionally, the ground was described with a gas model. Every kind of material data were selected on the base of experimental investigations. A bilinear material model with a Cowper and Symonds strain rate model was used to describe a vehicle. Such an approach fully describes the phenomena occurring in the system.

The aim of presented work is examination of blast wave, especially incident and reflected wave pressure. Due to many difficulties and complexity of phenomenon a complete study for different charges should be done. In presented paper two cylindrical TNT charges were used, weighting respectively 100 g and 200 g. Pressure wave was examined using original test stand designed and developed on Department of Mechanics and Applied Computer Science. A test steel test plate with 5 mm thickness was equipped with pressure gauge to measure reflected wave. Additionally, the plate was placed on four special electroresistance strain gauges...To measure force Vishay EA-06-120-060LZ strain gauges were used. For amplification of the dynamometers with strain gauges, MS1001 INFEL bridge was used. The system was used to validate the results from reflected wave pressure gauge. Shock wave pressures was measured using a special sensor model 137A21 amd M350B21 made by PCB Piezotronics At specific distance there was also incident wave pressure gauge. In order to fully examine the dynamic response of the plate an accelerometer was used. As a result, pressure versus time and acceleration versus time plots were obtained. The results will be used to validate numerical model of blast wave impact on a plate.

Numerical simulations without preliminary validation and model verification are vulnerable to errors. Best results are obtained when full experimental research is provided. Such tests are expensive and may be dangerous. Due to cost control and personnel safety, studies are often done in scale. Scale can affect both construction dimensions and applied load. In this paper four different vehicle's bottoms are examined: flat bottom and 3 types of deflectors. The paper presents four different vehicle's bottom shapes in order to examine deflector angle influence on energy absorption. The test included 4 cases: flat bottom broken-shaped deflector and deflectors with different apex angles 124 centigrade and 144 centigrade. For all cases the distance between explosive and panel was approximately 400 mm. The charge used was 100 g TNT. Flat bottom and deflectors were made of St3 steel with 2 mm thickness. For the purpose of the research a special test stand to examine effects of detonation wave was used. The force measurement system was designed in Department of Mechanics and Applied Computer Science. As a result, force versus time plots were obtained. The use of any deflector decreases maximum force affecting vehicle's hull.

IED (Improvised Explosive Device) – those special type of mines have occurred in the last decade with particular intensity in the recent Afghan conflict. Due to their structure and the use of large weights of explosives, the improvised explosive devices pose very high risk on any wheeled AFVs. There is a need to have some logistic solution, to security transport of damaged AFV. Polish army needs a new semi- trailer, which would be able to transport damaged AFV on it, from Afghan to Poland, by special cargo airplane, call "Rusłan". Although this paper does not cover mounting of the loaded flatbed to the deck of the aircraft, this subsection analyzes the way how the crew of AN 124-100 aircraft fixes the AFVs during the flight. This study is the result of the research and development project No.O R00 0085 12 "Ancillary flatbed for loading of damaged AFVs ROSOMAK on board of the plane." This paper presents the results from execution of the conceptual works related to the ancillary flatbed construction concept. The construction of technology demonstrator commences on the basis of a scientific and industrial consortium (Military Institute of Armour and Automotive Technology-Air Force Institute of Technology -CELTECH-HYDROMEGA).

Jednym z możliwych scenariuszy ataku terrorystycznego jest umieszczenie (podłożenie) improwizowanego ładunku wybuchowego (IED - improvised explosive device) na dnie basenu portowego w pobliżu cumującej jednostki pływającej. Wykorzystanie do tego celu pospolitych pojemników o rożnych kształtach, może nie budzić żadnych podejrzeń, tym bardziej, że pojemnik spoczywa pod powierzchnią wody, i z tego miejsca stanowi zagrożenie infrastruktury portowej, jednostek cumujących w porcie oraz ludzi i ładunku na ich pokładach. Uznając taki scenariusz za prawdopodobny, z wykorzystaniem nie budzących podejrzeń, pospolitych zasobników odpowiedzieć na pytania: Jaka ilość materiału wybuchowego (w pojemniku) jest niezbędna do uszkodzenia celu ataku? Jakie uszkodzenia a'priori wywoła określona ilość materiału wybuchowego dla różnej wielkości jednostek pływających? W odpowiedzi na powyższe pytania, dokonano analizy możliwości użycia różnych rodzajów pojemników, a na podstawie obliczeń strefy rażenia ładunku wybuchowego - dokonano oszacowania zakładanych uszkodzeń jednostki pływającej będącej celem ataku.

The one of the possible scripts of the terroristic attack on moored ship is to locate the improvised explosive device (IED) on the port seabed near to it. Utilization to this purpose quite ordinary containers, may not arouse any suspicions of the port authorities, but the threat of the seaport infrastructure, mooring ships, ships’ crew and cargo is obvious. Recognizing above as probable, there is a need to give answers for the important questions: Which quantity of the explosive charge indispensable for ship damage? What a’priori damages will trigger the definite quantity of the explosive charge for the various size of ship? As the answer on above questions, the analysis of the various kinds of containers for explosive charge were executed. Further, for the real conditions of the Gdynia seaport, on the basis of the calculations of the striking range of the explosive charge, the estimation of assumed damages for target ship was executed.

Currently, Improvised Explosive Devices (IED) are a weapon that is commonly used by terrorists. There are specialized combat engineering EOD subunits in the Polish Armed Forces intended to counter this threat. Due to their complexity and danger that they pose, the tasks carried out by these subunits can only be assigned to adequately prepared soldiers. On the basis of the literature and his own observations, the author hypothesizes that the above-mentioned subunits’ readiness to carry out their tasks is not adequate. Readiness should be perceived as a collection of factors influencing one another, such as organizational structures, human resources, military equipment, and training. Having analysed each of the factors listed above, the author concludes that due to the everchanging dynamics of the IED environment, it is necessary to continually improve combat engineering subunits’ readiness.

Electronic warfare and control of the adversary communications is one of the most important factors determining the success of a military mission. The information obtained from the sensors can provide data for situational awareness and the generated jamming signals are intended to block the adversary communication system. An important feature of these methods for generating jamming signals is to minimize their negative impact on own and allied systems. Moreover, improvised explosive devices IEDs are one of the major threats for equipment and people staying in areas of military operations. The IEDs are made using homemade materials. Their detonation can be done in many ways: wire detonation, using infrared sensor, noise detectors, pressure detectors, etc. For this purpose one can also use typical wireless radio systems like GSM, PMR, garage door opener, radio system using in children toys etc. This problem has been recognized also by the European Defence Agency (EDA ). It started ICAR (Intelligent Control of Adversary Radio-communication) project in 2009. During the project realization, a demonstrator of UGV mounted jammer was created. This paper contains assumptions and description of ICAR project. Next, a remote control station for UGV and a jamming system are presented, especially a structure of application and functionalities which can be used by the operator. Construction of the jamming equipment, functionality of the basic elements, purpose and capabilities of the control application are also presented.

The following paper is a review article. It is an attempt to analyze the most widely available publications of Salafi terrorist organizations addressed to European supporters. This article concentrates primarily on publications describing tactics related to committing acts of terror on civilian population. Organizations like AQ and ISIS suggest launching attacks using the most available resources (attack using a knife or a sharp tool, arson, ramming with a vehicle), constructing various kinds of IED (pipe bomb, pressure cooker bomb), encourage to attack in public and poorly protected places or advise on how to organize a shooting and hostage-taking situation. Moreover, they state bluntly that theft, vandalism or causing major traffic accidents are also actions which can help in the war with infidels. The substantive value of the instructions is questionable – the authors of many of them (e.g. the attack using a knife) have vague idea about equipment and combat. The content of these publications suggests that they are prepared for people relatively young, with no general experience in life and combat training. Terrorist organizations skillfully select passages from Quran and hadiths to find a pseudo religious justification for barbarism and cruelty. Finally, they treat all victims indiscriminately – all infidels deserve to die and killing them is a glorious achievement.
