Hi All,
I hope I've come to the right place. I have posted this in the rotorhead section but perhaps this is a better place! I'm a private pilot (fixed wing) and it turns out I'm writing a thesis on the static stability of helicopters. However, in my early stages of research, I'm not finding much information probably because I'm typing the wrong stuff in to search engines and looking for the wrong thing in libraries. Here's my question:
I understand that there are five characteristic modes of flight for fixed wing aircraft:
Short Period Mode
Phugoid Mode
Spiral Mode
Roll Mode
Dutch Roll Mode
There is plenty information on this and i've done research into these modes. However, my task is to find the characteristic modes for helicopters and research them deeply.
I know there is an equivalent for the dutch roll mode. What are the others? An explanation would be great, however if you can simply name them, at least I have somewhere to start with my research!
Just so my question is clear since I've written a massive post here when I only have one question:
What are the characteristic longitudinal modes of flight for a helicopter?
Thank you and look forward to hearing from you! :)
