Purpose: The development of modern aviation instrumentation assumes the introduction of airborne computer systems of integrated
modular avionics. To create such systems, special design solutions are required with a higher level of unification and standardization. The purpose of this research is developing structures of integrated modular avionics computing modules. Methods: The internal structure of the computational components was obtained using the methods of engineering synthesis, design automation systems, choice theory techniques and automated generation of design solutions. Results: The main result is the internal structure of the following modules: the computing module, the graphic module, the switch module, the input-output module and the mass storage module. In each case, the structure was obtained by modifying the unified computing component called "basic module". The basic module includes units which support the module, the intermodule interface, the functions of the module, the control and diagnostic of the external interfaces and the communication with the mezzanine boards. It also includes an intelligent power unit. The structure of the calculator coincides with the structure of the basic module. The input-output module is based on the basic module structure supplemented with mezzanine boards providing hardware and software support for the data input-output functions via specialized aiborne interfaces. To obtain the graphic module, the basic module is supplemented with a specialized graphic controller supporting the function of transmitting video via Fibre Channel interface. The switch module contains specialized elements: transmitters and receivers of Fibre Channel optical signal and Fibre Channel interface controller. The mass storage module structure assumes specialized mezzanine boards to expand the scope of the module memory. Practical relevance: The results were obtained during the research and development work on the design of advanced models of computing equipment for integrated modular avionics. These results have been brought to the industrial samples which are currently being tested.
