The pressure can be measured by pressure gauge or a piezoelectric pressure transducer. Each method is based on a different principle of pressure measuring, and for this reason, the obtained values of maximum pressure differ between individual methods. Due to that, it is necessary to know the functional dependence between these pressure measuring methods. This paper is focused on the analysis of experimentally obtained 7.62 mm × 39 ammunition ballistic pressure measurement results. Two different types of sensors are used; a pressure gauge and a piezoelectric pressure transducer. The experimentally obtained results are then the basis for the statistical analysis of the difference between the maximum pressures obtained by each method. The factors that could affect the magnitude of the difference between the maximum pressures obtained from the individual measurement methods are estimated based on the analysis of the provided results. The dependence of the methods is expressed as a linear function subsequently.","PeriodicalId":276923,"journal":{"name":"2021 International Conference on Military Technologies (ICMT)","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-06-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126641118","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In the working process, its parts always degrade under the impact of working conditions and the environment. This is a complicated process due to the complexity of the parts, systems used on the vehicles. However, the above process can be studied through typical single processes of manufacturing materials (metals, plastics, rubber, polymers, etc.), and some important elements, greatly affect vehicle performance (e.g., lubricants, batteries, electronic components, etc.). Understanding the nature of the degradation processes (phenomena, occurring mechanisms …) helps to find out solutions to overcome their limitation. Researching the failure mechanisms and phenomena on mathematical models is a research method with many advantages and low research cost. This paper presents a brief review of the degradation processes occurring on vehicles, and the models used to describe these processes. From that point out the content that needs further research in area “Mathematical modeling degradation process”.","PeriodicalId":276923,"journal":{"name":"2021 International Conference on Military Technologies (ICMT)","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-06-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124474057","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The BM-21 (Russia) multiple rocket launcher system with corresponding 9M22U unguided rockets have been used for the model simulation and experimental verification.

All of the surface targets of an air-to-surface mission are usually planned and loaded to aircraft before the mission. However, sometimes pilots may be suggested to destroy some unanticipated targets which are unplanned. In that case, pilots can be obliged to deviate from the waypoints of the planned mission in order to accomplish the new unplanned task and this can pose a great danger since there could be many potential threats around theater of war. In proposed method, surface threats and predictive launch acceptability region queries are modeled. Then, probabilistic roadmap algorithm with Dubins distance is applied to produce a waypoint trajectory which makes possible to reach closest goal state. The proposed method is proven by constituting a realistic simulation environment based on ROSplane considering mechanical and environmental factors. In total 25 flight simulations, the maximum observed deviation and the mean deviation from a waypoint are calculated as 11.1 meters and 2.2 meters respectively in a 5000m x 5000m x 300m space. Therefore, the results show that the proposed method can dynamically generate waypoint trajectories by using predictive launch acceptability region queries, which are safe and possible to follow.","PeriodicalId":276923,"journal":{"name":"2021 International Conference on Military Technologies (ICMT)","volume":"61 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-06-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131105298","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Unmanned aerial vehicles are used in both symmetrical and asymmetrical conflicts and are more often misused by terrorist and criminal organizations to pursue their goals or objectives. The approach to solving the problem of defence against unmanned aerial vehicles thus requires the involvement of all levels of air defence. These levels, also referred to as air defence pillars, in the form of sensors, effectors and command and control systems must then work synergistically against this threat. There is no unified solution to the problem of combating unmanned systems, or counter UAS (C-UAS), and therefore it is necessary to look for potential research topics. This article clarifies the main attributes of C-UAS and offers topics for research projects that will shift the capabilities of the solver and downstream user in favour of increased defence.","PeriodicalId":276923,"journal":{"name":"2021 International Conference on Military Technologies (ICMT)","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-06-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134569669","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
