2018-6-1 · Blades Forced Vibration Under Aero-Elastic Excitation Modeled by Van der Pol. NASA Astrophysics Data System (ADS) Pust, Ladislav; Pesek, Ludek. This paper employs a new analytical approach to model the influence of aerodynamic excitation on the dynamics of a bladed cascade at the flutter state. The flutter is an aero-elastic phenomenon that is linked to the interaction of the flow and …
