Improving the accuracy of measuring motion parameters and the volume of information exchange with aircraft requires the modern development of multifunctional radio systems that allow the combination of information and measuring channels due to frequency (time) signal selection. However, radio systems have limitations on the number and accuracy of the measurement of aircraft motion parameters, as well as information transfer rates. These restrictions will make it possible to remove laser systems for measuring with high accuracy the parameters of motion of aircraft. Similar laser systems are widely used in transmitting information to stationary or quasi-stationary objects. As a result, there was a need to overcome the contradiction between the requirements for the technical characteristics of radio systems and the capabilities of the existing scientific and methodological apparatus for synthesizing the signals of laser information-measuring systems for monitoring the parameters of aircraft motion. The theoretical foundations of the formation and selection of laser signals for combining the information and measuring channels of laser information-measuring systems are proposed and investigated. A comparison is made with known methods of combining (combining) the information and measuring channels of radio engineering systems and the features of using a spectrum of laser radiation formed by pairs of longitudinal modes that “color” each channel signal for their selection at reception. When receiving optical pairs of longitudinal modes, the intermode beat frequencies turn into radio engineering subcarriers that are well filtered and selectable. Based on the results of mathematical modeling and combinations of longitudinal modes, the choice of elements of a modified selector of longitudinal modes of laser information-measuring systems is substantiated. This determines the importance and usefulness of work for applied systems for measuring the parameters of movement of aircraft.
Проведено аналіз сучасних методів діагностування технічного стану каналів стволів та боєприпасів до вогнепальної зброї. Запропоновано перспективний метод діагностування, визначено його зміст. Обґрунтовано потребу у встановленні зв'язку між технічним станом каналів стволів та боєприпасів і характеристиками балістичних елементів пострілу. Визначено за доцільне розв'язування рівнянь внутрішньої балістики чисельним методом для моделювання перебігу процесу пострілу за наявності дефектів каналів стволів і боєприпасів.

The main principles of management of the scientific and pedagogical (scientific) team in a higher military educational institution, which ensure the coherence and efficiency of the work of units and individual employees, are considered. Specific conditions for the activities of scientists and scientific units for the structures of the security and defense sector, which should be taken into account when planning scientific work, have been defined. Approaches to the organization of scientific work at a higher military educational institution, which arise from the need to conduct hostilities to repel armed aggression, are described. The priorities that should be taken into account when reviewing the subject of scientific research and the structure of indicators of the results of the scientific activity of scientific teams have been formulated. The expediency of ranking the forms of scientific work by importance in accordance with the actual conditions of functioning of a higher military educational institution is justified. A variant of the distribution of forms of scientific work according to their importance is proposed. The need for periodic review of the degree of significance of various forms of scientific work in relation to others in accordance with the current state of the system of scientific work in a higher military educational institution was noted. The rational sequence of obtaining various forms of scientific products based on the results of the scientific activity of the team is given. The primacy of scientific research in the form of research work as a basis for obtaining scientific products is noted. Approaches to the formation of a matrix of scientific problems and tasks, which will determine the sequence of their solution and contribute to increasing the effectiveness of scientific research in a higher military educational institution in a certain set of their directions, are outlined. The connection between the content of the matrix of scientific problems and tasks and the content of the matrix of practical problems and tasks is noted.
