A method for compiling decomposition structure of aero-engine products

Abstract

The invention provides an aero-engine product decomposition structure preparation method, based on the technical process of system engineering, the steps are as follows, set the required content of "mission authorization"; use DOORs to conduct demand analysis; use function flow block diagram, N2 diagram or time Line analysis for functional analysis; refer to the existing engine architecture to design the architecture of the engine under study; According to the order of "Appendix" to divide the engine product hierarchy; judge whether the hierarchy division is appropriate; compile the engine product decomposition structure to place the relevant elements in the corresponding hierarchy according to the attribution relationship; judge whether the 100% principle, the principle of non-overlapping, and the high aggregation and low Coupling principle, meeting the requirements means meeting the requirements. The method provided by the invention can effectively improve the standardization, rationality and correctness of engine research and development, improve research and development efficiency, and increase the success rate of research and development.

Description

technical field [0001] The invention belongs to the field of aviation turbofan engine system engineering, and in particular relates to an aeroengine product decomposition structure preparation method. Background technique [0002] A large amount of product data will be generated during the development of aero-engines, and these data have the characteristics of clear layers, many changes, and a large time span. In order to more reasonably manage and control these data information and ensure its traceability, a product breakdown structure should be established , Hierarchical management and control of data. At the same time, in accordance with "GJB 8113-2013 General Requirements for System Engineering of Weaponry Equipment Development", relevant methods of system engineering should be strictly implemented during the development of aero-engines. Integration-Verification-Transfer-Confirmation" and other technical processes are implemented, and corresponding technical management ...

AI Technical Summary

Problems solved by technology

[0023] 4), the above two technologies 2) and 3) are aimed at aircraft, because there are certain differences between the research and development of aero-engines and aircrafts, so they cannot be directly applied to the compilation of the decomposition structure of aero-engine products
