Devices providing high fidelity simulation are becoming widely available in many sectors. In transportation, simulators have proven successful in personnel training, modeling nonstandard situations and even in development and research. The primary use of simulation is still focused on educational purposes. The simulated environment provides grounds for monitoring and assessment of trainees’ behavior. However, in addition to simulation technologies, other tools must be deployed. These tools record the physiological functions of the trainee and assess psychophysiological conditions. Specific events, such as a stressful situation, can be detected. Similar scientific-related activities may also lead to assessment of perception. This is a complex problem for both evaluation and data collection. Additionally, it puts specific demands on experimental equipment. The presented article describes the development of a flight simulation device that enables the evaluation of the pilots’ perception. This solution is based on X-Plane flight simulation engine with virtual reality (VR) and employs eye-tracking, brain activity monitors and heart activity monitors. The cockpit has a modular design and can be adapted to several aircraft types. VR-Gloves are used to interact with actual aircraft controls such as control yoke, thrust levers and even overhead panel switches. This setup creates a real-feel concept when controlling the aircraft. The presented solution is a technology demonstrator and is being tested with aviation training scenarios.","PeriodicalId":276923,"journal":{"name":"2021 International Conference on Military Technologies (ICMT)","volume":"33 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":"121851954","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}

A numerical model of gas flow motion in the gas cylinder is based on thermodynamics theory which was investigated, defined, and built into the CFD tool of the ANSYS FLUENT software. The approximate solutions are obtained by using k-omega turbulence model. Results show the velocity field, the pressure field, and the temperature field of the propellant gases flow in the gas cylinder and the cylinder walls. The comparisons between results obtained by the analytical model and the numerical simulation have been performed and good agreements were observed. These thermodynamic simulation results lay foundation to solve the problem concerning research into the gas-operated device's structural parameter design and to determine the location of high-pressure and temperature zones of gas block while firing, leading to the choice of materials and optimal design for gas-operated device details.","PeriodicalId":276923,"journal":{"name":"2021 International Conference on Military Technologies (ICMT)","volume":"93 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":"122185828","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 basic airport pavement distress is a crack, whose main criterion for evaluation is its width. In relation to air traffic safety, the cracks are divided into small, medium, or large categories according to the severity. A modern way of conduction of airport pavement inspection is the use of unmanned aircraft. This article explores the effect of unmanned aircraft flight parameter settings to recognize the distress on the concrete runway. The image data were obtained from the flights at several altitudes above the runway of a former military airport and processed using commercial multi-view reconstruction software. The output orthomosaic images were evaluated according to pixel resolution, ground sampling distance, and ground resolved distance. The correlation between the variables was statistically analyzed using linear and polynomial regression. The low flight altitudes bring a higher level of captured detail, but only the small area is captured, and more data needs to be processed, whereas higher flight altitudes cover a larger area with less data, but the captured detail is getting low. The findings reveal in order to capture the required detail; it is necessary to divide the length of the runway into individual legs, which allows the flight in lower altitudes above ground level. For the used unmanned aircraft, a balance between the flight altitude and the captured detail corresponding to the flight time per battery has been found. The captured data will be further used to create a database of individual distress for deep learning.","PeriodicalId":276923,"journal":{"name":"2021 International Conference on Military Technologies (ICMT)","volume":"87 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":"126177915","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}

Thus resulting kinetic parameters should correspond with kinetic parameters valid in storage temperature range from $10^{circ}mathrm{C}$ to $30^{circ}mathrm{C}$ enabling to make reliable models of stabilizer depletion during storage. AKA-II shows very low order of reaction and high activation energy leading to considerably long shelf life but harsh stabilizer depletion when the end of shelf life is nearing. Propellants stabilized by DPA shows common values of kinetic parameters and pretty predictable primary stabilizer depletion. EC shows very low reactivity and thus very long shelf life.
