Relevance Onboard computing systems (OCS) of modern aircraft (AC) have a system-oriented decentralized structural organization. The decentralized principle provides that the OCS is built in the form of a certain set of subsystems, between which the functional distribution of tasks is carried out. In this case, each of the specialized subsystems performs its functional task, exchanging, if necessary, information with other subsystems through the corresponding information transmission channels. However, as the functional tasks become more complex and their number increases, the decentralized principle of building on-board systems has largely exhausted its capabilities. First of all, this concerns such promising developments as the project to create a high-speed helicopter. The implementation of the concept of a promising high-speed helicopter requires the development of a high-performance on-board information and control complex capable of performing various functions in order to ensure high speed and long flight range, as well as the possibility of landing on unprepared sites. Aim of research The aim of research is to increase the performance of the on-board computer complex by forming an open architecture based on combining COST products, planning computing processes and choosing the optimal structural organization of the hardware. The objectives of the research project: 1. creation of a high-performance information and control complex based on open architectures and on the basis of integrated modular avionics; 2. using the optimization method of this complex to select the optimal possible solution to problems for a high-speed promising helicopter. Methods of research Method of generalized ranks is being worked out in detail. Ranking is made according to four criteria: total product volume, product weight, product availability, and product performance evaluation. Results The scientific novelty of this research project lies in solving problems associated with the formalization of procedures for the optimal configuration of the onboard information and control complex, based on the choice of methods for forming a set of acceptable options for onboard equipment that meet the modern concept of modular avionics, and the principles of heuristic optimization of the vector optimization base. The methods proposed in the work make it possible to improve the quality of the tasks assigned to high-speed helicopters by introducing a high-speed on-board information and control complex that meets the optimal requirements for performing the tactical and technical characteristics of a combat vehicle, which uses optimal COTS modules used on the basis of integral modular avionics. The introduction of the results of the research project into the development of promising high-speed helicopters will, according to estimates, increase the performance of the assigned tasks in front of the combat vehicle by 5–10 %.
