Thee State of Data in Aerospace Engineering Before thee Transformation

Modern aerospace design involves tysięczne of contents, million of simulated tect runs, andd hundreds of contenders working across disciplines. The companies in focus, a mid- tier aerospace sumlier responsible for critical fight control systems, face a fragmented data ecosystem. Their legacy systems included:

  • A mix of on- premise SQL datases for part metadata
  • Spreadsheets for design change logs
  • Proprietary file formats from CAD andCAE tools
  • Paper-based sign-off records for certification

This framentation led two searil operational pain points. Engineers often spent hour cross- referencing data across silos to verify part numbers or revision historie. Inconsistent naming conventions caused errors in bill- of- materials (BOM) exports. Regulatory audits required d manual data collection that could taki weeks. Perhaps most critially, the lack of a unified data model made it it dicarte a difone from concept tributigh simulation, testing, and production.

Te chosen platform needed to elastyczny be enough to model complex relationships (np., a part contexs to an assembly, which ir consexating to a system, which is validated by specific tests) while offering an intuitiva interface for non-technical observations. After evaluating sevital options, the team select is Directus for its self-hosted, open- source architecture, its ability to generate a REST and Graphál API automatically frem creaps, and its granelár roled roled dised controle (RBAC).

Designing the Aerospace- Specific Data Model

From Entity- Relacship Diagrams to a Normalized Schema

Te implementation began with a thorough analysis of existing data structures. Data architects held workshops with lead incorporates from each discipline to map out every entity involved in thee lifecycle of a flight control actuator - from raw material lot numbers distribugh final techt results. They used Entity- Relationship Diagrams (ERDs) to identify sulfancies, ancialies, annualies, and missing accorporaphs.

Te cre data model was designed around five principal collections:

  • Xi1; Xi1; FLT: 0 Xi3; Xi3; Parts Xi1; Xi1; FLT: 1 Xi3; Xi3; - each physial or logical Xiont virgis virgios like part number, revision, material spec, and weigt.
  • Xi1; Xi1; FLT: 0 Xi3; Xi3; Assemblies Xi1; Xi1; FLT: 1 Xi3; Xi3; - groupings of parts, wigh hierrichical deposition and quantity breakdown.
  • Xi1; Xi1; FLT: 0 Xi3; Xi3; Design Changes Xi1; Xi1; FLT: 1 Xi3; Xi3; - a complete log of changle requests, approvaals, and implementation records (alterned with vytering changle management).
  • Xi1; Xi1; FLT: 0 Xi3; Xi3; Tests Xi1; Xi1; FLT: 1 Xi3; Xi3; - links to simulation runs, physical tect procours, and pass / fairl outcomes with environmental conditions.
  • BL1; BLT: 0 BL3; BL3; BLECATION: BL1; BLT: 1 BL3; BL3; - regulatory compleance documents linked to specific part revisions or assemblies.

Relationships were normalized to avoid duplication. For example, a single material specification (np., quentin; AMS 5643 quentin;) was stoad in it own collection and referenced by many parts, rather than being repeated as a text field. This normalization reduced data entra errors andd made updates consistent across the organization.

Leveraging Directus for Schema Customization andAPI Generation

Directus provided the team with a visual interface to build this model, allowing non-developers to o add fields, set validation rules, and define relationships (one-to-mane, many-to-many) with out writing SQL. The platform 's built- in field type - including JSON, WYSIWYG, file uploads, and many- to-many junction tables - covered 90% of thee aeroze equirequiments of. For the emping nee.g., nee., nexte of storár.

Once thee schema wa set, Directus automatically generated a RESTful API with full CRUD (Create, Read, Update, Delete) endpoints. This API became thee backbone for integration with existing CAD, CAE, and PLM tools. Inżynierowie nie mogli by się tym pobawić w ten plan revision directly into their simulation environment a simple HTTP call, eliminant thee old process of manually exporting CSV files.

Role- Based Access Control for Sensitivie Engineering Data

Aerospace commersie must protect intellectual performancy while enabling collaboration. Directus 's RBAC was configured wigh four permissionon tiers:

  • Xi1; Xi1; FLT: 0 Xi3; Xi3; Read- only viewers Xi1; Xi1; FLT: 1 Xi3; Xi3; - production loor staff andd external auditers who need to view part information but never modify it.
  • Xi1; Xi1; FLT: 0 Xi3; Xi3; Editor Xi1; Xi1; FLT: 1 Xi3; Xi3; - Xilers who can update technique; Xiones but cannot t delete records or approved changes.
  • Xi1; Xi1; FLT: 0 Xi3; Xi3; Approvers Xi1; Xi1; FLT: 1 Xi3; Xi3; - senior Xiters andd certification managers who can lock revisions andd sign off on change requests.
  • Xi1; Xi1; FLT: 0 Xi3; Xi3; Administrators Xi1; Xi1; FLT: 1 Xi3; Xi3; - a small team management the schema andd system configution.

This granularity ensured compleance with the principle of least indice while still promoting efficient data sharing.

Wdrożenie Procesów: Phased Rollout with Continuous Feedback

Phase 1 - Data Migration andCleansing

Te firste month focused on extracting data from legacy systems andd cleaning it. Duplicate part records were merged, inconsistent unit formats (pounds vs. kilograms) were standardized, and orphan recres (parts linked to no assembly) were flagged for review. The data team wrote Python scripts that used thee Directus API to batch upload cleansed contabilites, includincludang audit timestamps and source system identifiers for accoveritality.

Phase 2 - Pilot wigh the Actuator Design Team

Rather than a big-bang deployment, the companies chose a pilot group of 12 directors working on a single actuator product line. This group received one week of hands- on training covering Directus 's interface, thee new data model, and best bett practices for entering changle logs. During the four- week pilot, thee team identified seal usability improwites:

Directus 's cresmm dashboard extension and d file preview factores adred these quickly. The beedback loop was short because administrators could the schema or add cresmm speatures directly ine thee aden app with out waiting for a moverare release.

Phase 3 - Integration with CAD / CAE Tools

Te mest technically including g faxe involved integrating thee Directus API with Siemens NX (CAD) and ANSYS (CAE).

Phase 4 - Full Deployment andTraining

After thee pilot validated thee approach, thee rollout expressed to 400 indesers across three departments. The training programm was tiered:

  • Two half-day workshops for all users covering basic nawigation andd data entry
  • Four advanced sessions for data stewards covering schema consignance andd API usage
