OpenRocket 🚀

OpenRocket is a free, fully featured model rocket simulator that allows you to design and simulate your rockets before actually building and flying them.

---

🛠️ Design, Visualize, and Analyze

1. Design your rockets using a rich selection of built-in components:

2. Visualize your masterpiece in 3D:

3. Plot & Analyze your simulation results for precision and improvements:

🌟 Features

• Six-degree-of-freedom flight simulation
• Automatic design optimization
• Realtime simulated altitude, velocity, and acceleration display
• Staging and clustering support
• Export to other simulation programs (RockSim, RASAero II)
• Export component(s) to OBJ file for 3D printing
• Cross-platform (Java-based)

... plus many more

📖 Read more on our website.

💾 Installers

You can find the OpenRocket installers here.

Release notes are available on each release's page or on our website.

📖 Documentation

You can find our documentation on ReadTheDocs.

🚀 Getting started

The easiest way to get started is to open one of our in-program example designs:

Dive into the essentials: adjust component dimensions, plot a simulation, swap out motors, ... Explore the impact of your changes and, most importantly, enjoy the process! 😊

💪 Contribute

Help us soar higher! Whether it's implementing features, writing documentation, or creating design examples, every contribution matters. Interested? Check out how to get involved and the practicalities of contributing.

openrocket.github.io's Issues

Add OpenRocket simulation accuracy comparison

A lot of users doubt the accuracy of OpenRocket, hell even we do sometimes. It would be really helpful if we would add a small section on the comparison of OpenRocket to other software (RockSim, RASAero), some real flight data, CFD analysis etc. Similar to RASAero: https://www.rasaero.com/comparisons-alt.htm.

Linux 3D isn't working

Hadn't been verifying 3D was still working for Linux after my system rebuild last week; discovered tonight it's not.

When going to a 3D view I'm getting an error in the window: "Unable to load 3d Libraries: XXX0 profile[2]: GL2->profileImpl GL3bc !!! not mapped

Hoping distributing as an appimage will let me include old enough openGL libraries to get it working again....

Photo studio broken in 23.09.beta.01

Parallax the Starfield

This could be a subtle but nice feature

Links to wiki pages should be https

Currently links are http, and the wiki does not automatically redirect (it should).

Add small history of OpenRocket

I think it would be interesting to add a small section on the history of OpenRocket (starting from Sampo's thesis, then going open-source, then some of the major updates, in short: something similar as the timeline that we did in the vNARCON presentation).

Rename 'Packages and Source Code' + change home page download button behavior

I would opt to rename the nav-bar 'Packages and Source Code' to 'Download'. Keeps it more concise and a Download-page is most often the thing people look for.

I would also suggest to change the download button behavior. Right now (in the development branch) it downloads the JAR-version of OR, but throughout the site we state that we strongly recommend to use the packaged installer. So my suggestion: make an operating system dependent download button that e.g. for macOS systems downloads the .dmg installer + add an option to download the versions of other operating systems.

Here is an example of the Blender download page of how I would prefer the download button to be:

Need new screenshots, and ensure that appropriate attribution/license is used.

• 3d view in the design page
• same model as above in photo editor
• motor chooser dialog
• possibly a couple of other charts - there are some "interesting" (but not necessary useful) where you can plot - say velocity vs altitude, or something like that

Note: The various backgrounds have different licenses, mostly CC-BY-SA, so either provide attribution or use one of the ones with a permissive license, either "Mountains" which I created and is public domain or "Frozen Lake" which is from Sampo and I assume we would have his permission. (The "Orbit" one is uncopyrighted, but NASA should be acknowledged according to their web page.)

Google Analytics

Do it.

Add screenshots to home page

It would be good to add some screenshots of the OpenRocket interface to the home page, preferably in some sort of carousel slider.

Highlight Current Page in NavBar or Provide Breadcrumbs

"Download" button on home page is effectively broken for some(or many or most?) users

Current behavior

Clicking the "Download" button at the top of https://openrocket.info downloads the OpenRocket .jar file. However, as noted on the Releases page...

If you have a more recent version [of Java] on your computer (as nearly everyone does), you will not be able to run the .jar file below without downgrading

This caveat does not appear anywhere on the home page!

OpenRocket will fail to run for users experiencing this problem, and will fail in incomprehensible ways, as evidenced by openrocket/openrocket#759.

Desired Behavior

For most users, the .jar file is (and should be) the option of last resort. Windows and Mac users almost certainly prefer .exe or .dmg installations, respectively. And Linux users may prefer .AppImage installations, although I'm not as familiar with that community so can't be sure about that.

Ideally the "Download" button would cause the appropriate installer (.exe, .dmg, .AppImage) to download based on the user's OS. Failing that, taking the user's to the Github Releases page where they will at least be apprised of the .jar issue, and can select the appropriate installer for themselves will avoid this unpleasantness.

Add alternative installation methods

OpenRocket is available through some package managers (such as snap). We should also include download instructions for those managers on our website.
