Methods & Assumptions

The workbench is built to keep modeling boundaries visible.

RPL Engine Workbench supports preliminary pressure-fed engine definition, injector and nozzle iteration, reporting, and flowfield visualization. Throughout the workbench and its reports, implemented workflows are kept distinct from validation status, qualification limits, and future work.

Thermochemistry

Supported propellant workflows use embedded CEA-referenced data, with optional local backends where configured. Backend provenance and any fallback are labeled in the results.

Injector and feed closure

Injector sizing uses explicit pressure-drop and geometry assumptions. Feed losses are treated as reviewable inputs or boundary conditions.

Nozzle geometry

Bell, conical, and TIC contours support layout, CAD handoff, and review. They are not presented as final contour optimization.

Flowfield Studio

Integrated visualization supports design insight, comparison, and validation planning. Final decisions require qualified analysis and test evidence.

Reports and exports

PDF reports, screenshots, videos, and DXF exports reflect the same solved case and include any warnings or stale-result context.

Safety boundary

The software does not replace hazard analysis, manufacturing review, structural qualification, flight readiness, or hot-fire validation.
