What is it about?
The most common technique for predicting aircraft flutter is by solution of a set of algebraic equations which are linear in the generalized coordinate amplitudes. These equations are nonlinear functions of several other parameters, opening the possibility of the nonlinear phenomenon bifurcation.

Why is it important?
Continuation methods have proven to be the most efficient and flexible way to solve flutter equations. The fact that flutter equations can exhibit bifurcation means it is important to be able to detect and treat bifurcation when using continuation methods.
Perspectives
This paper shows that detection of bifurcation in continuation solutions of flutter equations, though rare, is cheap and easy.
