spiral mode

[Marko J.]

Hello,

i try to avoid spiral mode instabiliy, how could i achieve this?
which parameters depend on on spiral mode.

I model a flying wing and the spiral mode is either negative damped or i get only a value t2.

thank you for your thoughts in advance

What is “a value t2”?

[Marko J.]

For this simulation i get a negative damped function for the spiral mode.
But sometimes i get only a value for t2.
