More flexible trapezoidal shapes for fins #223
Description
Is your feature request related to a problem? Please describe.
Again something that we got from discord server report.
RocketPy should be able to deal with trapezoidal fins even when they don't have trailing edge perpendicular to the rockets axis
Additional context
And then we have the comment from @MateusStano : "Unfortunately, RocketPy only simulates fins with perpendicular trailing edge. Having a non perpendicular trailing edge does make a difference in the static margin but it is very very small, your simulation shouldn't have major changes because of this"
