Design and regulation of aircraft maintainability based on technique model

With the development of digital design methods, the design of the maintainability of the aircraft systems is facing the problem of how to synchronize the function-performance design under the 3D digital design environment. This paper compares the main differences between the digital maintainability design and the traditional maintainability design, presents the maintainability design process in the digital design environment of aircraft, and studies the expression model of maintainability design parameters and the way of transformation, integration, and utilization of maintainability design information in the 3D design digital environment. Based on the graph theory and the network diagram, this paper proposes a design and control method of aircraft maintainability that is featured by the single task node maintenance time model and the maintenance process time model. It is proved by examples that the maintainability desgin technology based on digital model obtained in this study has certain engineering value for dynchronous maintainability design of equipment in the digital design environment.
