Hello everybody. I've got a rocket I am working on with an aspect ratio of about 22.5 (length to diameter). At this point, I am not concerned, but I was wondering at what point I would start to encounter issues or have to take other considerations into account if I were to increase the length? Someone had mentioned that the stability calculations that OpenRocket runs may become inaccurate as the aspect ratio increases significantly, having something to do with the surface drag of the tubes. I've looked around and all I have found is information along the line of "if you're under 30 ish you're fine."
I don't (currently) plan on designing such a long rocket, but I am still interested in knowing what the impacts could be if I were to make a rocket with an AR of 30 or even 40.
Thanks!
