Opis:: This paper presents many varied mobile platform suited for different kinds unmanned ground vehicles applications. The Unmanned Ground Vehicle's platform is the glue that holds together all the other aspects ofafield able tactical military unmanned ground vehicle. Unless the platform exhibits a high degree of mobility and outstanding ruggedness it will fail to achieve its target location. If the UGV can not deploy its sensor s at the correct location then the mission is rendered useless. The platform should merge the drive system, a power supply system sufficient for the required mission period, an advanced communication system capable of returning real-time information to the user and a user friendly Human machine Interface that allows long term, stress free operations. The platform must have a very high immunity to electro-magnetic interference, and logistically any tactical UGV must not impose a heavy load on available systems or manpower. Unmanned Ground Vehicle technology areas, platforms for reconnaissance, surveillance and EOD missions, the first dedicated IED disposat robotic platform "Wheelbarrow", remotely controlled French tank (AMX30B2) for mine clearance operations, All terrain vehicle Gamma Goat, schematic of typical hybrid electric power train for UGVs, AHED 8x8 Phantom view revealing power and propulsion are presented in the paper.

Opis:: Electric vehicles are increasingly present on the roads of the whole world. They have the opinion of ecological vehicles, not polluting the environment. Society is more and more often persuaded to buy electric cars as an environmentally friendly solution but is this for sure? Electric cars need quite a lot of electricity accumulated in batteries to drive on a long range. During the charging process, this energy is obtained from the electricity network, to where it is supplied by power plant. Electricity production from renewable sources is a privilege for the rare. However, electric cars are charged from the electricity grid, which in large part energy comes from non-renewable fuels. The efficiency of energy production in power plants and the energy transmission and conversion chain causes that only part of the energy produced in this way goes to the vehicle’s wheels. Although the power plants are equipped with more and more efficient exhaust gas cleaning systems, they do not clean them up to 100%. Sulphur, nitrogen, mercury and heavy metals remain in the exhaust. The article is an attempt to answer the question whether the total emission of toxic components associated with the use of an electric vehicle is not bigger than in a traditional internal combustion engine.

Opis:: Overcoming of road impassibility, increase of vehicle passability are the issues that are always actual for the areas with insufficiently developed road network in remote regions of the North, the Far East, Siberia, and also the lack of roads in oil and gas production places and their transportation to gathering stations. This issue is also actual during rescue missions after natural disasters, emergency situations and technogeneous disasters. To solve this important issue domestic and foreign industries produced and produce different kinds of off-road vehicles and snow and swamp-going vehicles: caterpillar, ski-caterpillar, on low-pressure tires. The advantage of the latter is the discovery of new opportunities in transportation, ecological compatibility, improved productivity and passableness. It is important to mention that almost all vehicles on extra-low pressure tires can swim. The fact that they all possess hermetic frame contributes to it, what is more, this usage of extra-low pressure tires provides this opportunity. This opportunity to deliver goods by the vehicles with extra-low pressure tires (VELPT), having no restriction in exploitation in summer and winter in the conditions of Arctic weak tundra, increases the competitive power of these vehicles compared to caterpillar off-road vehicles. Moreover, their usage is much cheaper than delivery by helicopter. All these lead to the popularity of VELPT, the growth of the number of their types for various purposes and appearance of new producers of this type of off-road vehicles.

Opis:: A problem of comparing the traction properties of Daewoo Lublin 3 Mi van with respective types of gearbox has been taken up in the paper. There were three gearbox types: TS5-21, PD.97 and ZF. These properties were concluded based on vehicle traction graph. They included: reaching the reserve driving force in respective gears, obtaining accelerations, overcoming the resistances to motion (rolling resistance, air resistance and grade resistance) as well as achieving the maximum speed. Vehicle traction diagram has been made based on the torque curve of Andoria 4CTi90 engine external characteristics obtained on engine test bed in a direct way using an AVL eddy current brake. The engine was supplied with a complete fuel dose and loaded with the resistance torque produced by engine brake. The characteristics was performed every 200 rpm from 1000 rpm to maximum revolutions and the other way from maximum revolutions to 1000 rpm every 200 rpm. The torque characteristics points were determined as a mean value obtained from these two measurements. After considering the data from engine external characteristics, vehicle information (including, among others, respective gear ratios and final drive ratio, under-the-bonnet power loss coefficient, and dynamic wheel radius) and the resistances to motion, a vehicle traction diagram of Daewoo Lublin 3 Mi van was made for three types of gearboxes. Based on this, the authors found that a Daewoo Lublin 3 Mi van equipped with ZF gearbox is the best from the point of view of traction properties.

Opis:: Armoured Fighting Vehicle (AFV) personnel are being subjected to high ambient temperatures, humidity and radiant heat loads for hours during deployments in the hot dry desert or warm humid tropical environment. The heat stress is even worst while operating the AFV in Nuclear Biological & Chemical (NBC) Protection mode. Maintaining crew 's physical and cognitive performance amidst all of the stressors of the battlefield is a huge tash. However, if the heat stress imposed by exposure to the climatic extremes of the environment can be controlled with the use of a microclimate cooling system then this allows the soldiers to remain focused on other critical tasks. Life Support System (LSS) is an integrated Microclimate and/or Individual Crew Cooling System (ICCS) integrated with NBC Protection system. The use of LSS or LSS that is complimented by Auxiliary Power Unit (APU) on modern AFVs ensures to the mounted soldiers the ability to maintain safe body temperature. This session will discuss the efficiency of LSS and LSS-APU on AFYs.
