https://openrocket.info/tutorials/ We'd love some feedback on these, along with suggestions for topics. Come talk to us on Discord, or join this new mailing list:

One additional note: If you’re having trouble with 3D views with the new version, try toggling the “Use off-screen rendering” setting in the “Graphics” tab of preferences.

Major new features of the 23.09 release include:

• 3D Printing Support: Export any select component(s) to OBJ file (File -> Export as -> Wavefront OBJ or the contextual menu)
• RASAero compatibility: Import / Export CDX1 files (File -> Import -> RASAero II and File -> Export as -> RASAero II)
• Dark Mode (normal and high-contrast) and custom UI font size support: See "General" tab in Preferences
• Export sim results table to CSV: select sims and then File -> Export simulation table as CSV File or use the contextual menu.

Major bug fixes:

• Fixed tube fin drag (most noticeable when using less than a full set of six tube fins)
• Fixed base drag when using Cd override (important when implementing Base Drag CP Correction)
• Fixed atmospheric pressure when using ISA conditions
• Properly sanitize XML in ORK file (eliminates corrupt ORK files that won't load)

And much, much more. Many thanks once again to our developers, testers, and users, and financial supporters. Happy simming!

There was an announcement on facebook almost 2 weeks ago. I downloaded it but haven't installed yet. Also for the past week or more every time I start OR it asks me if I want to download the new version.

I came back into the model rocket world after a 20 year break. I am retired now and Open Rocket has improved my enjoyment by 10 fold. I have learned so much about rocket design by using the program. I new nothing about CG and CP when kit building. Just put them together and fly. I design and fly all my rockets now by build from scratch using open rocket. Thanks for giving this old man something to enjoy again. I do have a question I would like some information on. I live about 100 miles from any club and fly by myself so this forum and my rocketry handbook by Stine is my only source in information.

I just undated my Open Rocket to 23.09 release. Can someone explain what the percentage number for stability means. I understand the caliber number fine but don’t know what the percentage is telling me. Percentage of what and is there a range I should be looking for?

Thanks

Steve

The percentage is giving you the same distance between cg and cp that the caliber figure is giving, but it's showing it as a percentage of the length of the rocket rather than as a multiple of the rocket's diameter. Many folk (myself included) believe that percentage is a better gauge of stability than calibers are, at least for rockets much longer or shorter than 10 times their diameter (which seems to have been roughly the length to diameter that whoever came up with the one caliber rule of thumb had in mind).
