Abstract: The bifurcation points of airfoil flutter system in incompressible flow are investigated in this paper. The theory of centre manifold is first used to reduce the flutter system to a two-dimensional one. Then the type and stability of the bifurcation points are analyzed by utilizing the method of succeeding function.

Key words: bifurcation, flutter system, centre manifold, succeeding function
