Aurora Space Systems
Methalox Orbital Engine
Reusable methane / oxygen propulsion architecture for orbital transfer, upper-stage duty, and future reusable space systems.
Public-safe technical posture
- No proprietary Blue Origin data or logos.
- No fake certified performance claims.
- Architecture-level subsystem credibility.
- Graphics use the approved rendering direction.
Public Architecture Brief
One engine page. Fourteen real assembly conversations.
This folder presents the Methalox Orbital Engine as a public, conceptual architecture. It highlights major assemblies and subsystem interfaces using credible, high-level data to support technical understanding and informed discussion.
Detailed private CAD, performance margins, proprietary materials, internal verification data, actual injector geometry, turbopump sizing, and control timings remain offline. The goal is to show disciplined systems thinking, not claim a flight-certified engine.
What engineers should see
- Feed, pump, injector, chamber, cooling, nozzle, controls, structures, manufacturing, testing, and reuse are treated as one system.
- The page avoids magic numbers and unsupported claims.
- Each card opens to a module page with public-safe technical text.
Engine Assembly Cards
Subsystem map
Graphics are pulled from the approved methalox render direction and reused as section thumbnails, with Card 1 using the larger technical callout rendering as requested.
