[0002] In the repair process of aircraft engine high-pressure compressor rotor blades, traditional data management relies on manual records and discrete data processing methods, which makes it difficult to share information in real time and accurately trace it, affecting the efficiency and quality of repair. With the development of advanced manufacturing technology, Model-Based Definition (MBD) technology has been introduced into the field of aviation manufacturing and maintenance. MBD technology is a method that combines physical design with digital models. It can integrate 3D model data, manufacturing information, and detection and analysis data, etc., to provide detailed data support for each link in the product life cycle.

[0003] In the existing technology, although MBD technology has begun to be applied to the design and manufacturing stages of aircraft engine components, its application in the field of maintenance and repair has not yet been developed. Due to the harsh working environment of high-pressure compressor rotor blades and extremely high requirements for material performance, every decision in the repair process needs to rely on accurate data support; any inaccurate or improper data processing may lead to repair failure and even affect the safe operation of the entire engine. However, at present, the process involves multiple links such as damage assessment, repair plan selection, and performance verification, which still lacks a unified data management and analysis platform, which limits the efficiency and accuracy of the repair work. Summary of the invention

[0015] The present invention discloses a high pressure compressor rotor blade repair data management system based on MBD technology, such as Figure 1 As shown, it includes an MBD data application unit, which includes a production scheduling module APS, a manufacturing execution module and a data acquisition module. The data acquisition unit is used to collect data before, during and after the repair of a faulty high-pressure compressor rotor blade. The production scheduling module is used to program and classify the process requirements according to the data before the repair of the faulty high-pressure compressor rotor blade and generate a repair strategy according to the classification results.

[0016] Specifically, the data acquisition module includes but is not limited to a radio frequency communication unit, a QR code, a Bluetooth communication unit and various sensors.

[0017] In order to realize the whole process management of high-pressure compressor rotor blades, based on the above system structure, the system also includes an MBD basic data unit, which is used to store and manage product models, product annotations, product attributes, and product process data to generate MBD technical specifications.

[0018] The MBD data application unit also includes the resource management module ERP and the quality management module QBOM.

[0019] Among them, the product model includes but is not limited to the 3D model and physical structure of the product, which not only shows the geometric shape of the product, but also includes the size and tolerance requirements that need to be followed during manufacturing and inspection.

[0020] Product annotations include, but are not limited to, additional information about the product or its components, including part markings, material specifications, heat treatment instructions, etc.

[0021] Product attributes include but are not limited to key performance parameters such as weight, mechanical properties, thermal properties, etc. These attributes are crucial to ensuring the functionality of the product.
