The Kyushu Yunjian PDM Product Data Management System Has Been Officially Launched and Is Now Operational.

　　In December 2019, the JiuZhou YunJian PDM product data management system completed debugging and was officially put into operation.

The PDM system, known in English as Product Data Management, focuses on managing product data throughout the research and development process. It serves as both the foundation and an extension of digital R&D, encompassing a wide range of management areas, including documents, 2D drawings, 3D models, testing and simulation data, product technical specifications, serialized product structures and configurations, workflows, organizational frameworks, and access permissions—essentially covering the core data and mechanisms crucial to an enterprise's operations.

So, what exactly is the significance of a PDM system for commercial aerospace companies? Why should companies invest effort into implementing a PDM system during the often-tight product design and development process?

Currently, commercial aerospace companies generally rely on 3D digital mock-up technology for product development and technological iteration. In this process, the implementation of a PDM system enables design data from various disciplines—such as power systems and engines—to be integrated online, facilitating collaborative design workflows. This approach fully leverages the advantages of digital design, maximizing efficiency and innovation in the development process.

1) Collaborative Design: Rapidly enhance the coordination and maturity of the powertrain system's 3D digital models, improve R&D design efficiency, shorten the development cycle, and make parallel development of multiple models feasible.

2) Unified Product Data Source and Change Management: Enables traceability of design history data and change processes, facilitating data version control and technical status management while ensuring data security and reliability.

3) Product Configuration: By defining and deriving product structures, we can provide the overall rocket customer with a variety of engine and propulsion system configuration options, thereby establishing a series of product packages tailored to their needs.

4) Product Reuse: Develop a "shelf-style" 3D model library comprising standard components such as fasteners (e.g., bolts, nuts) and reusable parts shared across different models, including fittings like ball joints and connector nozzles. This approach enhances product standardization, boosts R&D efficiency, and ensures reliable inheritance of design elements.

Jiuzhou Yunjian focuses on providing comprehensive product and technical support services for liquid rocket propulsion systems, with a strong commitment to refining and specializing in this field. To enhance the efficiency of product development, coordination, and iteration processes, while ensuring complete control over the quality and technical performance of engines delivered to customers, Jiuzhou Yunjian has established a PDM system. This system enables designers to collaborate seamlessly on 3D designs, allowing individual subsystem products to be quickly updated within the overall product model through operations such as check-out, modification, and re-check-in. Such an approach not only ensures rapid and efficient collaboration but also guarantees data security and reliability.

Next year will be a pivotal year for Jiuzhou Yunjian to achieve batch production and delivery of its propulsion products. The company's engine technical status management and quality control systems will face significant challenges during this period. To address these challenges, Jiuzhou Yunjian has implemented a PDM system that significantly alleviates the cumbersome workload of design personnel in managing product technical statuses, effectively mitigating potential risks associated with uncontrolled technical states. This system not only enhances the R&D team's collaborative efficiency and cohesion but also provides robust support for subsequent parallel development efforts, rapid iteration cycles, and ultimately ensures high-quality product delivery to our customers.
