Zusammenfassung:
Wing rock is an uncommanded rolling motion which has been observed for slender aircraft. The interaction of vortices is at the heart of the phenomena. Computational fluid dynamics can be used to predict wing rock through time accurate simulation. However, a parametric search based on unsteady calculations is computationally costly. Different approaches to the calculation of wing rock are considered in this paper, including direct stability calculations to determine onset angles, linearised time domain simulation and reduced order modelling using proper orthogonal decomposition.
