The main destabilizing factor during SC operation in orbit is the temperature deformation of the structure due to the constantly acting "heating-cooling" thermal cycles. The properties of carbon fiber allow it to be used in dimensionally stable truss structures of spacecraft. The influence of space factors on the properties of carbon fiber over time has not yet been sufficiently studied. Therefore, it is necessary to study the effect of thermal cycles on the change in the geometric parameters of carbon fiber structures over a long period of time. Research has been conducted and the effect of thermal loads of varying intensity and duration on the dimensional stability of tubular elements of truss structures for spacecraft has been assessed. Requirements have been formulated and a design and layout scheme of an experimental truss for resource tests has been developed. Studies were carried out on tubular elements of square cross-section, which are one of the main components of the model truss. A selection of materials, manufacturing technology and reinforcement scheme for tubular elements has been made. For manufacturing a dimensionally stable truss from composite materials, it is most preferable to use a composite base…

High-chromium cast irons are complex multicomponent alloys, so it is necessary to consider a number of features of alloying elements influence on the nature of phases formed in such alloys, as well as the processes occurring both during crystallization and during cooling of the casting in the solid state. In this regard, studies were conducted on the structure of high-chromium alloys with different chemical compositions. The structure of the high-chromium alloy was studied by X-ray spectral microanalysis, properties of the high-chromium alloys were determined by measuring hardness and microhardness. Heterogeneity of element distribution in the primary austenite grain was revealed. The chromium content varied from 4.7% in the region bordering the carbide to 14.9% in the grain center. The content of nickel, chromium, and manganese remained virtually unchanged across the specimen cross-section. Heterogeneity of silicon and molybdenum distribution across the specimen cross-section was revealed; their content is increased toward the center by 1.5–1.8 times. The carbide phase of the high-chromium alloys was represented by cementite-type carbides (Fe, Cr)<sub style="color: #000000; font-family: Verdana, Arial, Helvetica, sans-ser…

As one of the most common civil uses of UAVs, photogrammetry requires platforms offering flexibility, endurance, and cost efficiency. The research identifies end-user demands and defines system-level requirements that shape UAV design, production, and deployment. It stresses that establishing these requirements early is crucial to avoid expensive modifications later in the project lifecycle. <p class="a" style="color: #000000; font-family: Verdana, Arial, Helvetica, sans-serif; font-size: 10px; font-style: normal; font-variant-ligatures: normal; font-variant-caps: normal; font-weight: 400; letter-spacing: normal; orphans: 2; text-align: start; text-indent: 0px; text-transform: none; white-space: normal; widows: 2; word-spacing: 0px; -webkit-text-stroke-width: 0px; text-decoration-thickness: initial; text-decoration-style: initial; text-decoration-color: initial;">A systems engineering approach analyzes UAV deployment, incorporating technical, economic, operational, social, and regulatory factors.

When conducting experimental studies, the varying parameters changed in the ranges: roughness parameter Rz = 1…500 μm (Rz = 1, 25, 100, 300, 500); pressure in the volume of accumulated chips p = 0.00275…0.00975 MPa (p = 0.00275, 0.0055, 0.0075, 0.00975); humidity changed at two levels (excessive presence and complete absence of water). The results of the studies showed that the greatest influence is exerted by the variation of the roughness parameter (an increase in the coefficient of resistance to chip movement by approximately 3 times). Wetting also has a significant effect (an increase in the resistance coefficient to chip movement by 2-3 times). The smallest effect of the considered parameters is exerted by the change in pressure in the moving volume of chips (a decrease in the resistance coefficient to chip movement by approximately 1.8 times). The maximum change in the resistance coefficient to chip movement within the studied range of parameter variation is from 0.23 to 1.36, which represents approximately a sixfold increase. Based on the results of experimental studies, regression models of the change in the resistance coefficient to metal chip…

Electrohydraulic forming technologies for relatively small sheet parts are widely known. In such technologies, the energy release technology is created on one electrode pair, which allows for the deformation of small parts. Original electrohydraulic presses with high stored energy (up to 500 kJ) have been developed, which allows for the release of energy simultaneously in many zones of the working space above the workpiece. And this, in turn, allows the workpiece to be loaded only in certain zones. <p style="color: #000000; font-family: Verdana, Arial, Helvetica, sans-serif; font-size: 10px; font-style: normal; font-variant-ligatures: normal; font-variant-caps: normal; font-weight: 400; letter-spacing: normal; orphans: 2; text-align: start; text-indent: 0px; text-transform: none; white-space: normal; widows: 2; word-spacing: 0px; -webkit-text-stroke-width: 0px; text-decoration-thickness: initial; text-decoration-style: initial; text-decoration-color: initial;">Various technical requirements may be imposed on large sheet bottoms, i.e. limiting the deformation of thinning in certain zones, minimal elastic grooving of the part or especially high accuracy of its surface. <p style="color: #000000; font-family: Verdana, Arial, Helvetica, sans-serif; font-size: 10px; font-style: normal; font-variant-ligatures: normal; font-variant-caps: normal; font-weight: 4…

This creates a discrepancy between traditional means of information representation (drawings), designed for visual perception, and the requirements of automated systems, which need precise analytical models. It has been demonstrated that the parallel use of two description languages (descriptive geometry vs. analytical geometry) leads to the formation of two independent models of the same object and violates the principle of unity information space. <p style="color: #000000; font-family: Verdana, Arial, Helvetica, sans-serif; font-size: 10px; font-style: normal; font-variant-ligatures: normal; font-variant-caps: normal; font-weight: 400; letter-spacing: normal; orphans: 2; text-align: start; text-indent: 0px; text-transform: none; white-space: normal; widows: 2; word-spacing: 0px; -webkit-text-stroke-width: 0px; text-decoration-thickness: initial; text-decoration-style: initial; text-decoration-color: initial;">As a solution, the concept of an Analytical Reference of a Part (ARP) – a unified digital model containing the complete set of technological attributes for all stages of the product lifecycle – is proposed and substantiated.

Thus, it can be reasonably stated that perfection of aircraft in various appearances is largely determined by joints. On the other hand, at the stage of developing the main load-carrying scheme of a structure, simplified models are used, where the attachment zone or concentrated load is represented as a geometric locus of conditional points, where the reactions are summed up. Thus, the procedure for attachment designing, loads, etc. is completely independent, where the results of preliminary structure design in regular zones are used as initial data. It should be noted that the design of fastening units is carried out under more severe conditions than in regular structures: it is necessary to "fit" into the allowed space, fastening and supporting elements are selected according to standards for metal products, etc. A separate group of problems is created by the fact of using composites in load-carrying structures. These problems are associated with the distinctions of composites behavior in transition zones. On the other hand, the calculation and design of joints are limited by selected models. <p style="color: #000000; font-family: Verdana, Arial, Helvetica, sans-serif…

AI-DRIVEN CROSS-PLATFORM APPLICATION DEVELOPMENT SYSTEMS
type: item
description: The study is devoted to the analysis of the current state and prospects for the development of artificial intelligence (AI) in cross-platform application development systems. The key machine learning technologies used in software engineering automation processes are considered, including automatic code generation systems based on large language models, intelligent development environments, and AI-driven testing methodologies. The architectural solutions of modern cross-platform frameworks and their integration with artificial intelligence technologies are analyzed. The application of transformer models, in particular GPT-4/Codex, Claude, CodeT5, and CodeBERT, in the tasks of understanding and generating software code is studied. The analysis showed that currently GPT-4/Codex is the most accurate and powerful AI model suitable for complex code generation. CodeT5 maintains a balance between size and performance and therefore is well suited for code transformation tasks. InCoder specializes in filling in code patterns but has lower accuracy. CodeBERT is more suitable for code analytics than for generation. Methods for assessing the quality of AI-generated code are considered, including metrics of functional correctness and structural quality. Challenges to the security and reliability of automatically generated software code are highlighted, including vulnerability issues and the need for additional verification. An analysis of the effectiveness of various approaches to cross-platform development using artificial intelligence tools is presented. The scientific novelty of the work lies in the comprehensive analysis of the interaction of artificial intelligence technologies with cross-platform development frameworks, the systematization of modern approaches to AI-driven code generation, and the study of specific challenges in integrating machine learning into multi-platform software development processes. The results of the study show the significant potential of integra…
