The subject of the study is the spacecraft solar panel that represents a frame with modules with photocells attached to it. The object of the study is mechanical oscillations of such a panel as a multi-mass compliance structure. The article presents a modal analysis carried out to determine the natural frequencies and forms of vibrations of the spacecraft solar panel. A finite element model of the panel was developed. In the paper, a modal calculation was carried out on the basis of the model. A test facility was developed to carry out full-scale tests. According to the experimental studies, the model was refined, which made it possible to obtain a discrepancy in the results of no more than 2.5 Hz.","PeriodicalId":33287,"journal":{"name":"Vestnik Samarskogo universiteta Aerokosmicheskaia tekhnika tekhnologii i mashinostroenie","volume":"23 5","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-11-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135875076","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 peculiarity of the proposed technique is the use of small-sized UAVs to study the aerodynamic characteristics of various aerodynamic configurations and new engineering solutions. The main feature of the software and hardware implementation of the methodology consists in the use of small-sized electronic elements and electromechanical components available on the market in order to develop a sufficiently universal system of airborne measurements. The description and technical characteristics of the developed system are given. The system was tested on a specially designed and manufactured UAV with a traditional aerodynamic configuration that was designed using well-known and sufficiently reliable aerodynamic characteristics for such aircraft. The results of processing the data of the flight experiment and the aerodynamic characteristics calculated on its basis are presented.

It is noted that already in the Gospels God appears as one in three persons. The assumption is based that the existing anti-Trinitarian interpretations proceeded rather not from the Gospels, but from the interpretation of God in Judaism, in which he has no hypostasis. It is noted that within the framework of trinitarianism for a long time there were disputes about the ratio in the Holy Trinity of God the Father, God the Son and God the Holy Spirit, which ended in the division of churches. However, heresy-declared anti-Trinitarianism (Unitarianism) continued to exist. The article demonstrates the confession of this direction by I. Newton. It is noted that in the early 1990s, a community arose in the Soviet Union, claiming to develop Christianity and the doctrine of which, in a number of parameters, coincides with Gnosticism. The interpretation of the problem of hypostasis in it is analyzed.","PeriodicalId":33287,"journal":{"name":"Vestnik Samarskogo universiteta Aerokosmicheskaia tekhnika tekhnologii i mashinostroenie","volume":"36 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136112277","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}

At different times and in different areas, there may be no communication and interaction between these fields of knowledges. The relationship of natural sciences, technical and technological knowledge may not be an interaction, but have a focus only in one direction from the donor area to the acceptor area. These relationships can occur in opposite directions, that is, they are actually an interaction. There are special areas of scientific and technical knowledge that have arisen and are developing as a coherent integral system, i.e. natural science technical and technological knowledge in it is inseparable. In the historical process of interaction of natural sciences, technical and technological knowledge, one can observe the development of an increasing spiral. Each round of such a spiral includes a sequence of historical episodes: new natural sciences knowledge, their synthesis with technical developments when creating a new research tool, new experimental possibilities that determine the receipt of new natural science knowledge and further along the ascending trajectory to the next round. For example, the creation and improvement of steam engines in the 18th and 19th centuries led to the emergence of thermodynamics, which determined the development of many fields of natural science and technology. Also, research in the field of microbiology and enzymology in the 19th and 20th centuries led to the extensive development of biotechnology, organic synthesis technologies and biosensors. In the 20th century. scientific research on crystal lattice defects led to the discovery of semiconductors and a revolutionary change in the element base of all radio engineering systems that have found application in many fields of natural science and technology. At the same time, sources of coherent electromagnetic radiation were created lasers, which also spread throughout all areas of technology. In the system of natural sciences, analytical chemistry stands out, which is a synthesis of fundamental knowledge and applied technology. Research in supramolecular chemistry and nanotechnology conducted in the 20th and 21st centuries became the scientific basis for the production of electrical and optical devices; for the development of targeted medicine delivery technologies in a living organism, as well as for the creation of molecular machines. Research and technological developments in the field of microelectronics have led to the progress of informatization and digitalization of all areas of human activity. Many areas of modern natural science are becoming more and more technologically advanced, and modern industrial technologists are becoming more and more scientific. Technological knowledges spreads with necessity in many areas of the modern education system.
