Designing onboard cable networks components considering the manufacturability requirements

The design of the onboard cable network components of an aircraft that meet the requirements of regulatory and technical documentation is considered. The stages of the life cycle of the aircraft are noted, at which the analysis and evaluation of the technical solutions adopted at the design stage of the aircraft, aimed at adaptability to the installation and dismantling of products and components of the aircraft, take place. The scope of the design documentation required for the manufacture of onboard cable network components is determined. The peculiarity of the design stages and the inconsistency of the requirements of the regulatory and technical documentation used in designing onboard cable network components of the aircraft are indicated. A set of requirements for manufacturability, efficiency, reliability and electromagnetic compatibility of onboard cable network components is formalized. The criteria for the harness manufacturability are determined. A method is proposed for synthesizing the image of the onboard cable network components using a graph which vertices are supplemented with attributes that characterize the features of a wired connection to the elements of onboard systems. An algorithm of the designer's actions is developed when determining the need to introduce a connector into an electrical circuit, taking into account the requirements of the electromagnetic compatibility of wires. Recommendations for designers of aircraft onboard cable network components are formulated.
