Hi,
Is there a standard that people have used for sizing hardpoints in their monocoque? I've used the ECSS-E-HB-32-22A (European Cooperation for Space Standardization) but have realised this doesn't capture the effects of the insert being inserted between the inner and outer skin rather than the 'through-thickness' layout considered in this standard. There is very little literature on the aforementioned hardpoint design, so just wanted to know if there are any standards other people have used to size their hardpoints.
I understand that analytical models won't ever entirely capture the behaviour you would see in testing. I just want some kind of ballpark estimation for sizing so that I can then make test panels rather than just having a stab in the dark or blindly following what has been done in the past.
