The development of a new approach to assessing the durability and effectiveness of these barrels results from current solutions and capabilities of navigation and targeting systems, new generation projectiles (programmable ammunition with sub-projectiles) and real-time muzzle velocity measurement applications (while main-taining or even increasing the current muzzle velocity and rate of fire). This increases the probability of hitting floating, coastal and flying targets (especially UAVs and RAM). It has been shown that the durability and operational assessment of this class of guns (including economic efficiency) is not determined only by indicators based on the rate of fire, muzzle velocity or second burst of fire. What is now more important is the ability to reduce the rate of barrel destructive processes, resulting from the possibility of shortening the length of firing series. It has been shown that with short series, the barrels wear and the intensity of damage to the reload mechanisms are significantly reduced. The phenomenon of barrel overheating is also limited, and thus operational indicators are improved (average time to failure, continuous operation time, ammunition usage), which significantly reduces the cost of operating the guns.","PeriodicalId":439139,"journal":{"name":"PROBLEMY TECHNIKI UZBROJENIA","volume":"10 5","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-12-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138994376","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 contaminations are challenging for specialised laboratories dealing with their detection and identification of sources of origin. Unfortunately, such contaminations have a serious influence into the human health causing for instance significant injuries of human systems and organs, and long term problems with the health such as cancer diseases and other serious health disturbances. Therefore, it is important to focus attention on these threats, and to do everything possible to prevent their appearance and minimise the harmful effects. A low concentration of tested agent, below the instrument detection threshold, is a frequent problem at investigations of ecosystems. In such cases biomarkers of cumulation prove to be very helpful. Biomarkers can be a perfect tool for detection of contaminations in the flowing water and in the ground. They can be used to establish the presence of specific chemical agents and at the same time they are a sensitive indicator of ecosystems reaction to the contamination. A universal method was developed basing on the liquid chromatography for analysis of trotyl and its derivatives present in larvae of caddisflies from species of Hydropsyche angustipennis, Curtis 1834, and in the samples of soil, or in other complex matrixes. The chromatographic method can label quantitively and qualitatively different derivatives of trotyl, such as 2,6-diamino-4-nitrotoluene, 2,4-dia-mino-6-nitrotoluene, 1,3,5-trinitrobenzen, trinitrotoluene, 2-amino-4,6-dinitrotoluen, 4-amino-2,6-dinitrotoluen, and tetryl in a complex biologic matrix. Additionally, an effect was investigated of trotyl cumulation within 1 to 24 hours in the tissue of caddisfly larvae subjected to exposition of tested solutions contained trotyl. An effect of saturation was noticed and the concentration of trotyl derivatives was measured. Observed effects confirmed the usefulness of chosen larvae as a bioindicator of trotyl contamination accumulation in ecosystem.","PeriodicalId":439139,"journal":{"name":"PROBLEMY TECHNIKI UZBROJENIA","volume":"30 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-06-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117050926","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 typical barrel steels, e.g.30HN2MFA, a structural transformation occurs at about 730 , at which material shrinkage occurs. The way to increase the durability of the barrels is to change the steel grade to one in which this transformation does not occur or does occur, but at higher temperatures. The paper presents the results of experimental studies of all the above-mentioned thermophysical properties of five selected barrel steels, i.e. 38HMJ, 30HN2MFA, DUPLEX 2205, WCL and MARAGING 350. Measurements were made in the range from room temperature to about 1100 C. In this way, a database of thermo-physical properties of these steels was created as input data for the calculation of heat transfer in the barrels of small arms and cannons.","PeriodicalId":439139,"journal":{"name":"PROBLEMY TECHNIKI UZBROJENIA","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-06-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125074154","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}

On the other hand, an analytical solution of the system of nonlinear differential equations describing the phases of the phenomenon of a shot in a gun barrel does not exist. Therefore, in order to obtain more accurate solutions to the system of equations, it is worth to use numerical methods. The paper presents a theoretical description of the problem based on a review of analytical and numerical models solving the main problem of internal ballistics. Based on this analysis, it was assumed that a possible direction of development is to implement several models to solve the main problem of internal ballistics in numerical solution, so that the end user (designer) can choose different models and check which model works best in his conditions. In addition, using optimization techniques, an attempt can be made to implement algorithms that would be able to search for example, the smallest powder weight value at specific powder parameters and at given maximum pressure and projectile muzzle velocity.

Unfortunately, the national defence sector crisis management system has faced the second serious change for recent 10 years, and this time during the war in Ukraine. A quite legible division can be observed between the Command of Territorial Defence Troops and the Operational Headquarter of Armed Forces Services on the area of assignments protecting the population against the effects of natural disasters or technical failures in the first case, and on the area of assignments aimed to assist the services in keeping the internal security, including counteractions against terroristic threats, and ending on counteracting the military threats in the second case, what is presented in the paper. Unfortunately, it is not a holistic approach from the scientific point of view, and it also is not in line with the wordings of the National Security Strategy of the Republic of Poland from 2020. The justification for implementation of these changes can be proved by experience and conclusions of consecutive months and years, but it has to be added that the security environment is changing on a daily basis in this part of Europe.","PeriodicalId":439139,"journal":{"name":"PROBLEMY TECHNIKI UZBROJENIA","volume":"46 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-05-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121709795","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}
