Devising a method to design supersonic nozzles of rocket engines by using numerical analysis methods
Authors: Dubrovskiy Ivan , Bucharskyi Valeriy 
Published: December 2023

The object of research is supersonic nozzles of liquid-propellant rocket engines. The work considers the problem of the lack of an effective method for profiling the supersonic contour of the nozzle, which will generate maximum thrust. For its solution, a method is proposed, the essence of which is approximating the nozzle contour with a power-law polynomial and determining the values of its coefficients by solving a multidimensional minimization problem using numerical modeling methods. The expression for the axial component of the thrust with the opposite sign at the specified values of atmospheric pressure and radius at the nozzle section was chosen as the objective function in this paper.
Using the proposed method, contours of optimal nozzles were obtained based on polynomials of powers 2, 3, and 4, which were compared with nozzles obtained by the generally accepted Rao method. The maximum value of the relative deviation modulus calculated during the comparison did not exceed 3 %, which allows us to assert the correctness of the obtained results. The existence of such a discrepancy is explained by the difference in the numerical modeling method used. In contrast to the method of characteristics common in similar problems, the method of finite volumes of the Godunov type was used in the work. This has made it possible to reduce the sensitivity of the calculation to initial and boundary conditions and make decisions regardless of the flow regime of combustion products. In addition, the use of the extended cells method for the integration of finite volumes at the boundary of the calculation domain significantly reduced the total time of solving the problem of profiling the contour of the optimal nozzle

Authors: Peleshko Ivan , Yurchenko Vitalina , Rusyn Pavlo 
Published: December 2023

The object of the study was truss-type rod structures, which were investigated for the purpose of finding the optimal design solution in a mixed (continuous and discrete) space of variables. The parameters of the geometric scheme of the truss, as well as the dimensions of the cross-sections of its elements, were considered as design variables. The stated optimization problem is represented as a nonlinear programming task, in which the objective function and nonlinear constraints of the mathematical model are continuously differentiable functions of the design variables. The system of constraints includes strength and stability inequalities, formulated for the design cross-sections of the rod elements of the structure, which is subject to the effect of the design load combinations of the ultimate limit states. As a part of the system of constraints, the displacement constraints formulated for the specified structural nodes, which is subject to the action of design load combinations of the serviceability limit states, are considered. To solve the stated optimization problem, a method of the objective function gradient on the surface of active constraints was used, with the simultaneous elimination of residuals in the violated restrictions. For design variables, the variation of which must be performed according to a given set of possible discrete values, a discretization procedure for the optimal solution obtained in the continuous space of design variables is proposed. A comparison of the proposed optimization methodology with alternative metaheuristic methods and algorithms reported in the literature was performed. On the considered problem of parametric optimization of a 47-span tower structure, a design solution with a weight of 835,403 kg was obtained, which is 1.53...4.6 % better than the optimal solutions obtained by other authors
Approach to processing radio signals with amplitude modulation of many components using one-dimensional convolutional neural network
Authors: Tsymbaliuk Ivan , Horbatyi Ivan 
Published: December 2023

The object of research is the methods of using one-dimensional convolutional neural networks in radio receiving systems in order to increase their interference resistance.
The task of the research is to test the hypothesis about the likely higher efficiency of radio signal recognition under conditions of high noise (or weak signals) by neural network models of radio signal reception in comparison with trivial reception systems.
With the use of one-dimensional convolutional neural networks, a higher efficiency of extracting useful information from a signal-noise mixture at sufficiently high noise levels and, accordingly, a higher accuracy of radio signal recognition accuracy has been achieved. This result was achieved due to the specific architecture of convolutional neural networks, the ability to automatically detect important patterns in the data and analyze radio signals more deeply and informatively. Hierarchical representation of data with the selection of more complex and abstract features of the signal as the convolutional neural models become more complicated is one of the main advantages of using the proposed methods and algorithms under complex conditions of radio signal transmission.
The comparison with trivial methods of radio signal processing is performed on the basis of the symbol error probability parameter at different signal-to-noise ratios of the investigated signals and demonstrates a stable decrease in the symbol error probability at signal-to-noise ratios of less than 4 dB.
The results could be used in real radio communication systems, especially under conditions where it is necessary to quickly and reliably recognize radio signals among noise, under conditions of interference or with weak signals. They could also be useful in military applications, Earth remote sensing systems, mobile communication networks, etc.

The object of this study is the process of detecting and determining the coordinates of stealth unmanned aerial vehicles by a network of two small-sized radars. The main hypothesis of the study assumes that the use of two small-sized radars, which are connected in a network, could improve the quality of detection and determination of the coordinates of stealth unmanned aerial vehicles.
The improved method for detecting and determining the coordinates of a stealth unmanned aerial vehicle, unlike the known ones, enables the following:
– synchronous inspection of the airspace;
– reception of the signal reflected from a stealth unmanned aerial vehicle by two small-sized radars;
– carrying out coordinated filtering of incoming signals;
– compensation of phase shifts and coherent addition of output signals from matched filters;
– formation of Doppler channels in each small-sized radar and formation of a complex envelope from the output of the corresponding Doppler channel;
– coherent processing (addition) of signals;
– compensation of the random initial phase of signals reflected from a stealth unmanned aerial vehicle by detecting the output signal from the coherent adder;
– measuring the range to a stealth unmanned aerial vehicle by each small-sized radar;
– calculation of the coordinates of a stealth unmanned aerial vehicle.
It was established that at low signal/noise values, the gain in terms of the conditional probability of correct detection is from 25 % to 32 %. It was determined that the use of a network of two small-sized radars makes it possible to reduce the mean square error in determining the coordinates of a stealth unmanned aerial vehicle from 28 % to 37 % on average

An issue related to using concrete for building structures is to ensure their stability and durability during operation within wide limits. Therefore, the object of research was the change in the properties of concrete in case of fire and its protection when applied with a reactive coating capable of forming a foam coke layer under the influence of high temperature on the coating. It has been proven that in the process of thermal action on the fire-resistant coating, the process of heat insulation of concrete involves the formation of soot-like products on the surface of the material. Thus, under the influence of the flame of the burner, a temperature arose on the surface of the sample, which led to the swelling of the coating by more than 18 mm. The measured temperature on the surface of the concrete sample under the layer of foam coke was no more than 140 °C, which indicates the formation of a fire barrier. In this regard, modeling of the process of heat transfer through the formed layer of foam coke in the process of its protection with a reactive coating was carried out and dependence was established, which makes it possible to estimate the coefficients of temperature conductivity and thermal conductivity during high-temperature action. According to the experimental data and the established dependences, the coefficient of temperature conductivity and heat conductivity of foam coke was calculated, which is 9.17·10–7 m2/s and 0.17 W/(m∙K). The assessment of the maximum possible penetration of fire through the layer of foam coke was carried out. A temperature was formed on the surface of the sample, which significantly exceeded the temperature of the destruction of concrete, and on the surface of concrete under the coating it did not reach 250 °C. So, there are reasons to assert the possibility of targeted regulation of concrete fire protection processes by using reactive coatings capable of forming a protective layer on the surface of the material that inhibits the rate of heat transfer

Authors: Bychok Alla 
Published: December 2023

During the training of highly qualified specialists of the "Business Communications and Translation" program, the course "Linguistic Studies (in German) is studied. In this course, teaching methods and tools are widely used to ensure perception and consolidation with the help of feedback and self-control and taking into account the individual capabilities of students of authentic material of a country science nature. The aforementioned discipline contributes to the formation of communicative and translation competence for effective communication, as well as adequate translation and mutual understanding. Thus, in classes, those methods and teaching tools are widely used, which provide an opportunity to improve students' communication skills in combination with grammar skills.
In our study, the methods and means of education are considered through the prism of training students – future translators. This makes it possible to prepare qualified and competitive translators for work on the world market of labour and services with appropriate interdisciplinary coordination of all cycles of humanitarian and specialized educational disciplines. It is a well-known fact, that perfect command of a foreign language involves not only the knowledge and ability of students to correctly use lexical units in combination with grammatical constructions at the level necessary for oral and written communication. In the educational process, students learn to perceive information of authentic content by ear and improve their reproduction skills. In practical classes, future specialists learn to model professional situations in German in order to prepare for foreign language professional communication, as well as when writing business letters, drawing up annotations, able to conduct dialog-conversation, presentation-advertising and presentation-report.
When training future translators, it is essential to evaluate the achievements of the culture of native speakers in German-speaking countries, to understand its essence, meaning and role for humanity. The fact of awareness of the importance of using information and computer technologies in order to improve professional activity is integral. It is also worth paying attention to the personal traits of the communicator - the future translator: features of the use of oratory, sociability, self-development skills and self-evaluation in certain professional and communicative situations. Such methods as "Brain-ring", press conference, round aquarium, simulation games, game design, trainings, creation of a situation of success, etc. contribute to this. The following tools are important: the Internet, virtual simulators, audio and video recordings of a creative direction, video conferences, presentations

ISOLATION OF HIGH PURITY PIPERYLENE
Authors: Shevlyakov Fedor B. 
Published: December 2023

Piperylene is a valuable raw material component for petrochemical synthesis, perfumery and cosmetic products, and is used as a solvent for petroleum products in the production of synthetic rubbers and latexes, and in the paint and varnish industry. Piperylene in the form of a fraction is produced in the production of isoprene by the two-stage dehydrogenation of isopentane, where it is a secondary product of the main synthesis. Isolation of commercial piperylene of high purity will allow the production of a value-added product and expand the sales market. Currently, restrictions on the production of commercial piperylene are associated with the high content of an impurity – cyclopentadiene. Previous studies by the author showed the feasibility of extracting cyclopentadiene at the stage of obtaining the catalyzate of the second stage of isoprene dehydrogenation. Simulation of the technological scheme in the application program showed that, together, the extraction of cyclopentadiene by a chemical method and a change in the technological operating mode makes it possible to isolate piperylene with a content of 99.45 % wt and CPD equal to 0.0046 % wt.
