The invention belongs to the field of aircraft research and development process construction
technology management, and relates to an aircraft product
configuration item division adjustment management method. The method comprises the steps of S1, classifying configuration items according to
design data types, and dividing the configuration items into a
machine body structure class, a matched product class, a pipeline class, a wire harness class, a guarantee equipment class and a technical
data class; s2, performing
configuration item selection step by step based on an aircraft product
decomposition structure, and forming three types of resource trees of universal configuration, selected installation items and customized items from a project level, an aircraft level, a
system level, a subsystem level and a subsystem level; s3, starting
configuration item division in the detailed preliminary
design stage, wherein each configuration item is divided according to a specified division principle; and S4, in a detailed
design stage and an
engineering change stage, performing content adjustment on each configuration item by adopting a graded auditing and signing process. The technical
state management efficiency of the whole life cycle of the aircraft is improved.
