About Rocket Propulsion Lab
Rocket Propulsion Lab is a small, founder-led, independent software company. It builds one product: RPL Engine Workbench, a native Windows and Apple silicon Mac application for preliminary design of pressure-fed liquid rocket engines — sizing, injector and nozzle geometry, reports, and flowfield visualization. The product has been in active development since 2023.
How the software is built
The application is written for engineers who will check its output. Every solved result carries its inputs, assumptions, thermochemistry source, units, and convergence state. Fallbacks and estimates are labeled instead of hidden, non-converged results are never presented as converged, and stale outputs are cleared when inputs change. The same rules apply to this website: no invented customers, no invented validation.
It is preliminary design software. It does not substitute for qualified engineering judgment, testing, safety review, or legal and export-control compliance — a boundary stated in the app, in the reports, and here.
Who uses it
University rocket teams, small propulsion companies, consultants, and independent engineers doing early pressure-fed liquid engine design, documentation, CAD handoff, and test correlation on Windows or Mac.
Name disambiguation
