Whirl Flutter Predictions for Distributed Propulsion Tiltrotor Congurations
Journal of the American Helicopter SocietyA family of generic hingeless hub distributed propulsion tiltrotor configurations was modeled in RCAS and studied for whirl flutter along with a baseline conventional configuration for comparison. A sensitivity study was carried out using the baseline model to provide a fundamental understanding.

Effectiveness of Direct and Hybrid Piezoelectric Control for Whirl Flutter
AIAA JournalWhirl flutter plays an important role in the current aeronautical scenario. Due to the advent of modern air mobility, more efficient propeller-driven aircraft have been sought. This type of aircraft is susceptible to such a phenomenon, as it can influence performance and operational life, cause undesirable behaviors and failures, and affect the design ...

Uncertainty Estimation in Experimental Whirl Flutter Modes Identification
Proceedings of the Vertical Flight Society 81st Annual Forum and Technology DisplayThis paper deals with the uncertainty estimation of identified frequency and damping trends of whirl flutter modes, obtained by applying system identification methods on experimental data. In particular, two different identification approaches are considered, namely the free-decay analysis by using Matrix Pencil algorithm and the Data-Driven Stochastic
