It was a big oops!I doubt OR will SIM that correctly,, but a phantom fin set could be added, to adjust results.
Was that an "oops" or did you intentionally can't the fins? What is the angle? Are they all canted the same way (induced spind) or are 2 on one side opposite direction 2 on other side (offset spin, but cause "side slip" from trajectory)?
I'll look into the SIMs for various arrangements, and how predicted apogee changes.
Sorry to hear that, but we've all been there to some extent or another...(myself many times.)It was a big oops!
Because I was happy to just get straight tubes fixed!For reasons not entirely clear to me, OR doesn't support canted tube fins. However, if you just enter them as regular tube fins, you should get a sim that's pretty close. The cant isn't that steep.
Can you say that again? I’m completely lost.roll coupling going that causes coning.
Thanks for that btw!!Because I was happy to just get straight tubes fixed!

You’re looking at this all wrong. The canted fins won’t make a difference in performance (flat fins canted 10 degrees only shave a couple of percent off of altitude). You’re experimenting with canted tube fins since OR doesn’t handle that.It was a big oops!
As programers say “it’s not a bug! It’s a feature!”You’re looking at this all wrong. The canted fins won’t make a difference in performance (flat fins canted 10 degrees only shave a couple of percent off of altitude). You’re experimenting with canted tube fins since OR doesn’t handle that.
It’s not an error, it’s science!
That was a little helpful, I found out what coning is still confused about roll coupling (it sounds like some sort of Bering)
My (very limited) understanding is that roll coupling happens when an object starts off rotating about one axis and then due to the magic of 6-degree-of-freedom dynamics transitions into rotating about other axes. AFAIK, that's typically only an issue in hobby rocketry on either very high (say >50K feet) or very high performance (say >Mach 2-3) flights.That was a little helpful, I found out what coning is still confused about roll coupling (it sounds like some sort of Bering)
Well then I’ll ignore it then as a cyclotron is not what you’d call a performance rocket.My (very limited) understanding is that roll coupling happens when an object starts off rotating about one axis and then due to the magic of 6-degree-of-freedom dynamics transitions into rotating about other axes.

THANK YOU FOR ALL YOUR WORK. I know the Tubefins, were a hiccup when at the 11th hour it fell apart somewhere in the rewrite process a few versions ago.Because I was happy to just get straight tubes fixed!
