RustPEP documentation

Getting started

Install RustPEP and evaluate your first propellant recipe.

Install

RustPEP 0.1.0 runs on 64-bit Windows and 64-bit Linux. Get it from the downloads page.

Windows

Three packages, all containing the same application:

  • Setup program (.exe): a standard Windows installer.
  • MSI installer (.msi): a Windows Installer package.
  • Portable (.zip): unzip anywhere and run RustPEP.exe. Nothing is installed.

The 0.1.0 Windows installers are not code-signed, so Windows SmartScreen may show a warning. Each download lists its SHA-256 checksum if you want to verify the file first.

Linux

Pick the package that matches your distribution and install it with your package manager.

Debian, Ubuntu and other .deb distributions:

sudo apt install ./RustPEP_0.1.0_amd64.deb

Fedora and other .rpm distributions:

sudo dnf install ./RustPEP-0.1.0-1.x86_64.rpm

Your first recipe

  1. On the Formulation page, search for an ingredient on the left and click it to add it to the recipe. Or open the Propellant Library and load a published formulation.
  2. Type the weight of each ingredient in grams. Percentages update as you type.
  3. Set the chamber pressure you expect the motor to run at, and the exit pressure (14.7 psi at sea level).
  4. Results recalculate automatically.

Scale to 100 g rescales the recipe so the weights read directly as percentages.

The pages

Page What it is for
Formulation Build a recipe, set conditions, read the results
Propellant Library Published and reference formulations to load and adjust
Studies Sweep an ingredient, chamber pressure or nozzle expansion ratio
Compare Up to four recipes side by side
Burn Rate Fit r = a·Pⁿ from BATES test firings
Export BurnSim summary, CSV, PDF data sheet, PEPCODED ingredient file
Help Quick start and definitions inside the application

Saving your work

Save and Open on the Formulation page store and reload a recipe. New starts an empty one.

Before you rely on a number

Results are ideal thermochemical predictions. They do not predict burn rate, combustion efficiency, nozzle losses or safety. See Data sources and limits.
