Documentation

Build, simulate, fly, and compare. All in one place.

ZenRockets gives you everything you need to design a rocket, simulate its flight, import real flight data, and visualize the results. These guides explain what each tool does and how to use it effectively.

Start with Building a Rocket
Build
Building a RocketStart from scratch, an example, or an import — then find your way around.Working with PartsStages, part families, tree organization and selection.Sizing & PositioningDimensions, placement references, radial layouts and fin outlines.Using MotorsPick catalog or custom motors, set ejection delays, build clusters.Recovery & StagingDeployment choices, recovery devices and multi-stage flights.Preparing to SimulateMaterials, overrides, stability, thrust and validation status.Using Presets & MaterialsApply, save and manage reusable part specs and material data.
Motors
Building a MotorDefault template or clone, and a tour of the motor editor.Configuring a MotorCase, propellant grains, nozzle and ejection in real dimensions.Creating Custom PropellantsAuthor a propellant with combustion data in the Propellants dashboard.Simulating & Comparing ThrustRun the sim, read performance, and resolve design issues.Static Fire DataImport test-stand thrust traces and fly with measured data.
Flight
Running Flight SimulationsSet conditions, understand model assumptions, and manage runs.Understanding Flight ResultsSummary numbers, charts, playback, events and atmosphere.Comparing FlightsChoose flights, align time, compare results and share access.
Data
ImportOpenRocket and RockSim designs, RASP motors and flight logs.Flight Data ImportCSV flight logs — column mapping, reconstruction, event review.Export & 3D PrintingExport printable parts as 3MF files for 3D printing.Units & SettingsMetric/imperial presets, per-category units, SI storage.
Misc
SafetyReading results as estimates, and launching within laws and codes.ChangelogEvery release of ZenRockets, grouped by year, newest first.AcknowledgementsOpen-source projects, data sources and community work ZenRockets builds on.
