Hi,
The limitloads (per definition in e.g. FAR part 23) relate to dynamic or static loads?
I have seen airliners being tested to ultimate design limit, but it looks like static testing.
So, hypothetically, if you experience turbulence (gust load) that exerts +3.8g and then -1.5 followed by another +3.8g, are the limits still safe?
I assume that within +3.8 and -1.5g structure is exposed only to elastic deformations. But I wonder how many such dynamic cycles (ie.g. how long can it fly in strong turbulence) can a structure withstand or did they design it so that n-number of cycles is approximatelly unlimited within these limits.
I am aware of fatigue problem etc due to other factors from environment but I wish to clear this stuff in my head
Thanks for replies!
