What we build
One integrated desktop workbench that connects sizing, injector and nozzle workflows, DXF export, reports, and Flowfield Studio — so design assumptions stay consistent from the first solve to the exported artifact.
About
An independent studio building engineering software for pressure-fed propulsion.
Rocket Propulsion Lab is an independent engineering software studio. We build RPL Engine Workbench, a native Apple silicon Mac application for pressure-fed rocket engine sizing, geometry, reporting, and flowfield visualization. The product has been in active development since 2023.
How we work
Founder-led and engineering-first. We prioritize traceable results, honest labeling of assumptions and fallbacks, and clear boundaries on what the software does and does not establish.
Who it is for
University rocket teams, aerospace startups, contractors, and independent engineers who want a local Mac workflow for preliminary design, iteration, documentation, and review.
Principles
Preliminary design software, stated plainly.
RPL Engine Workbench supports design iteration and review. It is not a substitute for qualified engineering judgment, testing, safety review, or legal and export-control compliance. We keep that boundary visible in the app, the reports, and on this site, and we label fallbacks and estimates rather than hiding them.
Name disambiguation
RPL Engine Workbench is independent engineering software and is not affiliated with university rocket-propulsion laboratories unless expressly stated. "Rocket Propulsion Lab" refers to the software studio that publishes this product.
