Full six-degree-of-freedom simulation for high power rocketry. Wind, staging, clustering and dispersion — solved, not assumed. Built for L3, research and anything where the margin actually matters.
No subscription. Runs in your browser — nothing to install.
Standard gets you altitude and stability for a simple single-stage flight. Pro handles the cases where a simplified model quietly gives you the wrong answer.
A 3-DOF model assumes the rocket points where it's going. Real rockets don't — they pitch, yaw and roll, and that coupling is exactly what produces the surprises. Pro integrates all six.
A rocket doesn't meet one wind speed — it climbs through layers of them, each with its own direction, and gets shoved on the way up. Pro models the column, not a single number.
Separation events and air-starts introduce failure modes a single-motor model can't see. Pro simulates each stage as its own vehicle with its own mass, drag and stability.
A simulation you can't hand to anyone is half a tool. Export geometry and aero data to your modeling stack, and generate reports that answer the questions a waiver application asks.
Simulation is a prediction, not a guarantee. Results depend entirely on the accuracy of the mass, geometry and atmospheric data you provide, and no model fully captures a real motor on a real day. Always fly within your certification level, follow NAR and Tripoli safety codes, and defer to the RSO on site.
One payment, and Pro stays unlocked. No renewal, no subscription.
You'll receive a license key by email at the address used at checkout. Open the simulator, paste the key in, and the Pro features unlock — nothing to install or download. Keys are issued manually, so allow up to one business day; if it hasn't arrived, email us and we'll sort it immediately.
No. One payment, and the license is perpetual. Because the simulator runs in the browser, improvements reach you automatically at no extra cost. A future major version may be a separate paid upgrade.
Standard covers single-stage flights with a 3-DOF solver, stability analysis, motor database and recovery sizing — enough for most L1 and L2 flights. Pro adds full 6-DOF dynamics, wind modeling, multi-stage and clustering, Monte Carlo dispersion, and export and reporting.
No. The simulator runs in your browser, so it works on desktop, laptop or tablet with nothing to install. Your key unlocks Pro wherever you sign in.
Not strictly — certification requirements come from NAR or Tripoli, not from us. That said, the dispersion analysis and flight reporting exist specifically because L3 projects tend to raise questions that a single nominal trajectory doesn't answer well.
Yes. OpenRocket .ork files import directly, along with .eng motor files and CSV thrust curves.
Email us and we'll make it right. Tell us what went wrong — for a $19 tool we'd rather refund you quickly than argue about it.
