I'm looking for reliable data on maximum instantaneous turn rates for jet fighters, something coming from reliable sources, ideally official flight manuals or specifications. I can't seem to find anything. I've seen reports of turn rates around 35°/s for some fighters (F-22, Typhoon, Rafale) but I don't know whether those can be trusted: https://defenseissues.wordpress.com/2014/01/11/comparing-modern-western-fighters/
If possible I'd like to have data on fighters with exceptionally high maximum turn rates, but really, anything would be welcome. Even information on old, retired fighters would be nice, and I guess that's more likely to be declassified. Failing that, a lower bound would be useful.
I don't know if turn rates make much sense for helicopters, but that information would also have some value.
