Propulsion engineers
Size from chamber targets and export the geometry without rebuilding the workflow each time.
Rocket engine design software
Rocket engine design software for an integrated local workflow.
RPL Engine Workbench is rocket engine design software that connects sizing, injector and nozzle workflows, DXF geometry export, reports, and flowfield visualization in one native Windows 11 and Apple silicon Mac application — built for preliminary design, iteration, documentation, and review.
Mac 1.0.0 · signed and notarized. Windows 1.0.0 Public Beta · unsigned. Preliminary design software for analysis, iteration, documentation, and review.
Who it is for
For engineers who want fewer tool handoffs.
One workbench keeps performance, geometry, and reporting tied to the same solved case.
Design reviewers
Read assumptions, warnings, and convergence state alongside the numbers.
Small teams
Keep a consistent, traceable workflow without standing up cloud infrastructure.
Workflow
What the software does.
The same solved case drives sizing, geometry, reports, and visualization.
Sizing modes
Solve from thrust, mass flow, throat diameter, injector geometry, or tank pressure.
Geometry and DXF
Generate bell, conical, and TIC nozzle contours and export DXF for CAD.
Reports
Produce PDF reports that show assumptions, warnings, and backend provenance.
Flowfield Studio
Inspect density-gradient and plume behavior with transient playback (included with every paid license).
