Hi There,
I already read that there has been an update of the compression rib layout on Pitts aircrafts somewhen in the past.
Now, in the Skybolt Delta drawings there is a rib shown looking quite like Curtis donated that update to the Skybolt too. The rib is called "Butt rib". Sadly my English is far from good enough to interpret that nomeclature. I tried google, turned out it could mean compression rib as well as root rib.
Can anybody tell me how I have to understand that.
And If it is meant to be compression rib, is it for the upper wing only or should I adapt it for the lower wing, too? (What would make most sense to me)
The drawing number is: 404 (2 of 2)
Cheers
Flo
