{"title":"Simulation Modelling of the Process of Birds Fly into the Turbojet Aircraft Engine Fan to Determine Most Dangerous Cases in Terms of Blade Strength","authors":"Gennadii Martynenko, N. Smetankina, V. Martynenko, V. Merculov, M. Kostin","doi":"10.1109/KhPIWeek57572.2022.9916474","DOIUrl":"https://doi.org/10.1109/KhPIWeek57572.2022.9916474","url":null,"abstract":"The paper considers an approach to numerical simulation of bird strike on the fan blades of an aircraft dual-flow turbojet engine. The purpose of such simulation modelling is determining the most critical cases of bird impact from the strength viewpoint of the blade apparatus. These cases are determined by the Airworthiness Standards for aircraft engines, which must be met for all of their designed components. However, only some of them are the most critical and subject to in-depth verification. To identify such cases, finite-element modelling using explicit dynamics methods is applied. The choice of the most critical case from the strength viewpoint of the blades is made between two variants simulating a flock of medium-size birds or a single big bird with given sets of parameters (mass, sizes, speed, angle) with the rotating fan wheel. The model of the fan impeller is used as a circular assembly of the sector of fan blades on a model disk with a hydrodynamic model of a single big bird or a flock of medium-size birds with discretization by the SPH method. A feature of the proposed approach is an algorithmic solution for damping parasitic oscillations of the blades that occur during the instantaneous application of the angular speed. The distributions of the main parameters of the stress-strain state of the blades depending on time are obtained. This data is an informative simulation of process dynamics. They allow assessing the possibility of failure of the material of the blades and the overall bird resistance of the structure. These virtual experiments make it possible to conclusively narrow the number of tested parameter sets for a given design class in compliance with the Airworthiness Standards. The proposed computational models and algorithmic schemes for carrying out numerical analyses are verified according to the data of bench experiments. The use of such computational analysis tools makes it possible at the design stage to reduce the time and resources spent by reducing the number of bench experiments required for certification.","PeriodicalId":197096,"journal":{"name":"2022 IEEE 3rd KhPI Week on Advanced Technology (KhPIWeek)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-10-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114067604","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}

It has been established that humic substances, which were obtained from brown coals by extraction method, are characterized by nano dispersion in the range of 52–380 nm. It was found that due to the presence of a large number of active functional groups on the surface of such nanoparticles of humic substances is a hybrid modification of polylactid by the mechanism of template synthesis, which is accompanied by an increase in the degree of crystallization and the formation of a more rigid polymer structure, which allows to obtain hybrid biopolymer nanocomposites with significant impact strength and breaking stress during bending. It was also found that the obtained hybrid biopolymer nanocomposites based on polylactid and humic substances are characterized by levels at the value of resistance from 25 to 31 Ω sq−1. It is concluded that the designed hybrid biopolymer nanocomposites based on polylactide and humic substances in terms of their strength properties and complex of spectral-electrical characteristics are a promising basis for obtaining polymer matrices and materials for micro- and nanoelectronics.","PeriodicalId":197096,"journal":{"name":"2022 IEEE 3rd KhPI Week on Advanced Technology (KhPIWeek)","volume":"64 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-10-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121722898","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}

An important property of TE generators and refrigerators from a practical point of view is their lifetime, which largely depends on the material used in a converter. The object of this study is solid solutions $(text{SnTe})_{100-mathrm{x}}(text{In}_{2}text{Te}_{3})_{mathrm{x}}(chi=0-8)$ based on tin telluride Sn'Te, into which In2 Te3 was introduced. After synthesizing polycrystals and measuring their properties (microhardness $H$, Seebeck coefflcient $S$, electrical conductivlty $sigma$ and TE power factor $P=S^{2}cdotsigma)$, we kept them at room temperature in air without a special protective coating for 20 years. After measuring their properties after the long-term aging, we found that the general behavior of the $H(chi), S(chi), sigma(chi)$, and $P(chi)$ dependences (specifically, an increase in $H, S, P$ and a decrease in $sigma$ with increasing x) did not change. However, the long-term aging led to a more distinct manifestation of percolation effects accompanying the transition to heavy doping, as well as the processes associated with the formation of complexes in a solid solution. As a result, the composition dependences of mechanical and TE properties acquired an oscillatory character, but their monotonic component almost coincided with the dependences measured before the aging.","PeriodicalId":197096,"journal":{"name":"2022 IEEE 3rd KhPI Week on Advanced Technology (KhPIWeek)","volume":"84 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-10-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122732402","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}
