Seeking wisdom:
I cut out these fins and then beveled them to 15° on the leading and trailing edges. I did some moderate sanding on the bevel, but there are still grooves present from the burr.
Wondering if this will significantly impact the flow over the fin at all - ie will it impact performance significantly versus if I fill in the grooves? My intuition says No, but I'm not sure what the Science would say - I did some initial googling but couldn’t find info to answer that question specifically.
This is a 3 inch minimum diameter rocket, that will likely see top exposure of Mach 1.5-2.0.
Thanks in advance.
