Abstract
The problem of calculating the Floquet transition matrix for parametric stability problems is considered. A method of calculating the transition matrix with a minimum number of time steps is described. The method is shown to be extremely efficient for a wide class of problems including flapping stability of a helicopter rotor, helicopter ground resonance with one lag clamper inoperative and dynamic stability of a column with a periodic follower force. The relationship of the method to the classical method of averaging is pointed out.
