For more specific, up-to-date information about Blue Origin and the BE-4 engine, I'd recommend heading over to the Blue Origin website. But for a rough contextual overview, the diagram below identifies many of the major components that make up the BE-4 engine.
I'm a System Design Engineer for the BE-4 program. Essentially what that means is that my team configures the top level engine design for each individual engine, and designs all of the connecting parts in the engine: tubes, ducts, secondary structure, ancillary systems, etc. For the BE-4, these parts are approximately 80% of the total engine part count. My daily work in this capacity involves:
- Detail Design and Drafting
- BOM Management
- Structural analysis
- Large Assembly Management
- Configuration Data Management
