Annotation: The application of modern information technologies in enterprises of the rocket and space industry is an essential component for ensuring the high quality of economic activity. These technologies, such as the design of new systems and parts, the management of production cycles, the optimization of logistics operations, and the maintenance of fi nancial, economic, and accounting documentation, are actively integrated into the automation of various processes. This approach enables not only meeting modern market requirements and technological standards, but also achieving a signifi cant increase in the overall effi ciency of the enterprise. To increase the productivity of the automated control system (ACS) databases of Yuzhnoye State Design Offi ce and organize the disk space on servers through data archiving, the problems that arise when implementing the algorithm for fi lling ACS databases were investigated, taking into account the distinction between working and archival information in modern domestic enterprises, and recommendations were developed for resolving those problems. Approaches to devising a methodology for developing software based on a single database for enterprise management were improved, taking into account the requirements of enterprises in the rocket and space industry, by creating new programs that allow the application of modern information technologies. The practical signifi cance of the obtained results lies in the development of recommendations that can be used in the activities of Yuzhnoye State Design Offi ce and other enterprises. The warranty period for the servers and data storage systems at the enterprise has expired, which resulted in failures of a signifi cant amount of IT capacity. The implementation of this algorithm allows for promptly reducing the load on computing power and enhancing the fault resistance of computer systems. It will facilitate the process of making appropriate management decisions and ensure that management personnel are provided with relevant, targeted, complete, practical, and comparable information.

Annotation: The use of information technologies in rocket and space industry enterprises to automate design, production management, logistics, fi nancial, economic, and accounting processes is a prerequisite for carrying out economic activities. The successful automation of the enterprise management system increases the effi ciency of management and enhances labor productivity by accelerating the exchange of information in coordinating various issues, switching to digital (paperless) document fl ow, reducing the infl uence of the human factor, and making it possible to adopt typical decisions automatically. Information systems and processes at enterprises must be interconnected because work management and accounting are impossible without information support in real life. Information systems not only record the results of business processes. They ensure the achievement of the set goal in compliance with numerous accounting requirements. The article examines the theoretical aspects of implementing corporate information systems to support the management activities of enterprises today. The primary problems and tasks of implementing enterprise management information systems have been identifi ed. The scientifi c novelty of the results obtained from this scientifi c research lies in enhancing corporate business management software based on a unifi ed ERP database and supporting space rocket enterprises by developing new programs, which allow accounting to be carried out using up-to-date information technologies. The practical value of these results lies in the development of recommendations that Yuzhnoye State Design Offi ce and other enterprises can apply. ERP systems allow you to online monitor the activities of all structural units, the completion of assigned tasks, and the achievement of key indicators. Programs of this class will facilitate the process of making the right management decisions by providing management personnel with relevant, targeted, and up-to-date information.

Annotation: The main parameters are understood as: carrying capacity mг, range L and fuel efficiency qт, which largely determine the competitiveness of aircraft of this type, including military transport aircraft. The reason for the creation of modifications of transport category aircraft is the requirement for a constant increase in their flight performance by increasing the carrying capacity and range. Among the main goals of implementing such decisions there is an indispensable increase in the fuel efficiency of modifications, since the cost of fuel reaches 80 % of the cost of an airplane hour during operation. There are a number of models that make it possible to assess the influence of the weight and aerodynamic parameters of the airframe of the aircraft and the fuel performance of the power plant (specific engine consumption) on the integral indicator of the fuel efficiency of the modification at cruising mode and the average hourly fuel consumption at the certification stage, when all parameters of the airframe and engine are fixed and consideration of options is not possible. A new model is proposed for the stage of designing modifications, in which deep modification changes are made in the geometry of wing and in the power plant with various variants of their correlation and coordination. The parameters of new model: specific fuel efficiency – specific route productivity, in order to form the relative carrying capacity and relative range of action for the required specific fuel efficiency. An analysis of such dependencies showed: – with an increase in relative range L , fuel costs per flight also increase; – the adequacy of changes in route performance is observed only at L < 0.5. At L > 0.5 productivity is constantly decreasing, while the specific indicator of fuel consumption per unit of work increases exponentially; – if in the analysis we take into account the specific value of transport efficiency, that is, the characteristic “load – range” ( mп.н  f L ), it becomes obvious that the most favorable (from the point of view of fuel efficiency) are relative ranges of 0,3 < L < 0,5. In this range L , not only acceptable fuel efficiency values are realized, but also the maximum value of the route performance, that is the main parameters for which modifications are developed.

Annotation: The process of introducing new technologies at Yuzhnoye SDO requires major changes of aerospace products designing methods and project management methods, which allows realizing new opportunities, reducing manufacturing expenses with simultaneous increase of products quality. New software products are presented directed at solving the problems identified when using additive technologies at Yuzhnoye SDO. Such as Autodesk Netfabb, AM Process Simulation, ESI Additive Manufacturing and others that allow optimizing the model for additive technologies through the change of material structure, taking into account and compensation of heat setting during printing propose the tools for creating bionic design. Creation of new technologies of producing cooled nozzle block of LRE chamber without soldering became possible due to integrated approach, with optimal combination of already existing technical solutions with principally new ones, such as laser welding and surfacing. The cost analysis is considered as the most effective optimization method at selection of optimal design and manufacturing technology for its possible implementation at the company. The personnel problem, the issues of quality improvement and labor productivity increase in all production phases are foundational to reduce manufacturing cost.
