Aeroelastic stability of a cantilevered plate in yawed subsonic flow

Experimental Aeroelastic Models Design and Wind Tunnel Testing for Correlation with New Theory

“…References [12,13] focus on exploring the transition of the limit cycle oscillation (LCO) response from a small yaw angle (flapping flag response for β = 0) to a large yaw angle (wing-like response, β = 90 • ) of a cantilever plate as the angle between the clamped edge and free stream velocity changes. In particular, [37] presents a nonlinear structural model for the rotated aeroelastic system.…”

“…This could be improved by using a camera with a higher resolution. For the detail experimental measurement, see Reference [12].…”

“…Based on these models several correlation studies for flutter/LCO [6][7][8][9][10][11][12][13][14][15][16] and gust response studies [17][18][19] were performed. (3) Airfoil section with control surface freeplay.…”

Passive oscillations of inverted flags in a uniform flow

“…In these studies, it was demonstrated that some intuitional results can be obtained readily using this linear theoretical model and that the coupling modes can be predicted qualitatively. Gibbs et al (2014) and Tang et al (2015b) further applied the vortex lattice method to consider vortex shedding from the trailing edge of a conventional flag and obtained theoretical results that are in good agreement with experimental results.…”

Numerical investigation of the effects of compressibility on the flutter of a three-dimensional, cantilevered plate in an inviscid, subsonic, open flow

“…We hope that our work may be useful for those researchers in the field of aeroelasticity interested in studying the flutter instability of a plate cantilevered at the leading edge subject to a three-dimensional subsonic flow, providing some insight about the influence of different parameters, such as the compressibility, the aspect ratio and the material properties. We also expect that the numerical method developed here be useful for future studies that consider different boundary conditions -e.g., inverted flags [52], yawed flows [53], sides attached to springs [38]-and/or different shapes of the plate. Other tasks could be addressed in the future, such as the inclusion of structural nonlinearities [54], the implementation of a higher-order aerodynamic scheme, and the extension of the analysis to supersonic flow.…”
