Description of the test stand for investigation of the integrated powertrain (powerpack) for armoured modular vehicle (AMV), disassembled from vehicle, is presented in this paper. The powerpack unit consist of a diesel engine, a gearbox and a cooling unit with a hydraulic fan drive. The stand is equipped with measuring devices for torque measure, fuel consumption, exhaust smoke and exhaust gas components emission analysers. The powerpack has been loaded by a hydraulic dynamometer of power range up to 1250 kW. It is dynabar water dynamometer with high dynamics of load changes. For control the motor and drive, system the original control panels from the vehicle was used. The original start-up unit, mid fuel tank and air filters were used too. Research on the powerpack unit was made in the steady state versus the engine load and speed. The parameters of the engine and exhaust components were measured and compared with the catalogue values. Two modes of engine work were compared-economic and dynamic modes. Those differences between two modes are result of maximum fuel consumption decreasing. The parameters of engine work were comparable in middle and low range of engine load. On the stand investigation in transient states during free engine acceleration were made. It was found that additional load of engine is too high and this problem should be clarified.
Basic problems relating to the passive and active protection of present fighting vehicles were introduced in this paper. The scripts of the working of armed strengths and threat what were self- characterized briefly they result from the applied at present armour-piercing guns, such armour-piercing grenade hand launcher, armour-piercing missiles, subcaliber bullets, kinetic bullets, ground mines and improvised explosive devices. Applied at present passive and reactive protections of fighting vehicles were introduced, protecting crews while hitting bullets in vehicles. The stages of detecting the threat and reaction on stepping out threats were analyzed, and this indispensable time on the effective answer of the system of the protection. The means of the counteraction were self- characterized the threats of vehicles, applied in the arrangements of the active protection. Proprieties some of worked out systems of the active protection of fighting vehicles and their basic tactical and technical parameters were introduced.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
