2 hours of calculations and all I proved is that ‘I know nothing’
My new area of fascination ‘computational fluid dynamics’ and what have I learnt ‘I know nothing’
This is way more complex than ballistics relating to firearms, closest I have found after hours of trawling the net is that a broadhead will behave more like a wind turbine than anything else I have found.
What I have learnt is that no matter what the broadhead will do you also have to consider all other components the biggest variable will be fletchings and that makes most of what I was trying to do worthless.
Homer is correct in quoting Doc Ashby, modeling a bradheads flight bears very little relationship to what happens when it contacts meat and bone.
