Abstract The paper aims at investigating the non-classical aileron buzz under varying flow conditions by means of the Describing Function Technique with multiple input variables. Using high-fidelity coupled Computational Fluid Dynamics/Computational Structural Dynamics models through time marching analysis, it is possible to predict the limit cycle stability and amplitude. The approach is computationally expensive, and thus a first attempt to use a multiple input Describing Function is introduced in order to represent the aerodynamic subsystem as lumped nonlinearities to reduce the computational burden. The present work shows that limit cycles can be reasonably identified by means of the Describing Function representation.
