Downloads and reference material

Everything on this page exists today. The website itself does not run engine calculations; the desktop application does, and the packages below are its exports.

RPL Engine Workbench trial — Windows 11

1.0.0 Public Beta · unsigned installer (x64)

The Windows 11 (64-bit) beta includes a guided .exe installer. The default per-user installation needs no administrator rights. The built-in trial needs no license key. The download page lists the final package size, SHA-256, and signing status.

RPL Engine Workbench trial — Apple silicon Mac

DMG · ~39 MB · notarized

The desktop application for Apple silicon Macs, version 1.0.0. The built-in trial needs no license key. The download page lists the SHA-256 and how to verify the signature.

LMAE reference project

ZIP · 0.22 MB

The complete Apollo LMAE reference package: a five-page comparison against NASA and contractor records, the application-generated 11-page report, the exported millimeter DXF contour, and the portable input-only project file. SHA-256 and sources are on the sample report page.

Sample report and validation notes

The LMAE comparison table with inputs, independently compared outputs, and claim boundaries, plus links to the NASA records used. The validation page describes the bounded reference cases and automated checks.

Pressure-fed design-review checklist

A static checklist for reviewing a preliminary pressure-fed liquid engine design.

Methods and assumptions

What the solver computes, which correlations and thermochemistry sources it uses, and where its limits are.

Tutorials

Step-by-step walkthroughs: engine case setup, nozzle sizing and DXF export, injector sizing, Flowfield Studio, residuals, and report export.

Glossary

Definitions of the quantities the application reports: c*, Cf, Isp, expansion ratio, momentum ratio, and the rest.

Linux interest

Windows 11 and Apple silicon macOS are available today. There is no Linux build; write to us if you need one so we can gauge demand. It is not a commitment to a date.
