Hi,
I have been working on a report about the stability of the Aerospatiale Puma SA330,, and shown that it has an inherent spiral instability.
I later found that this was due to coupling between the state matrix derivatives: ?aCos?, N’v and N’w for flying conditions with large bank angle.
Anyone any idea how to explain this?
