Interesting HLD bow explosion (Pic heavy)

--- Quote from: simk on November 20, 2018, 01:35:07 am ---would it be wrong to argue that a HLD profile in general needs less wood/mass to generate same strain/draw weight than other common cross-section designs and therefore should be more competitive? just asking...

It appears that concave belly would make wider portion of crowned back work in storing energy. For small diameter staves, this might be a better way to make the whole back work than de-crowning the back, by making the narrow limb work like a much wider one. I don't think the concave belly cross-section is more effective than the flat one. It would be more intuitive for the concave back cross-section as in Bhutanese bamboo bows should work better.

bradsmith2010:
if the concave belly was superior in perfromance, I think we would see more test results,,they are beautiful,, but I doubt they are superior in performance,, I am just guessing,,  :NN

bownarra:
I think these bows may store a little energy by trying to 'split' the belly in half. Interesting to think what the poisson effect is doing here ;)
I highly doubt they will work out faster than an optimised flat belly.

BowEd:
The age old proven process of keeping the majority of the mass on the inner limbs wide enough for less set with power and speed on wood bows I think holds true for any design.
These HLD bows are very interesting.Never devoted the time into one though.I feel they could get the best out of a highly concave sapling bow from less dense second string wood avoiding any decrowning to keep their width.
