Rocket Optimizer

Desktop app that searches solid rocket motor designs with openMotor’s ballistics engine and returns the ones that satisfy a set of limits.

• —Multi-objective genetic search (NSGA-II), plus a surrogate mode that fits models to every simulation so far and re-verifies each reported design at a finer timestep.
• —Closed-form BATES geometry and a core-ordering symmetry, checked against the simulator in CI, shrink the search space before any simulation runs.
• —Packaged for macOS and Windows with a GitHub Actions release pipeline. Exports PDF reports, design sheets, openMotor files and a RASP .eng for OpenRocket.

• —Applying force modeling and drag estimation to guide hardware decisions.
• —Iterating hardware configurations against defined performance targets.
