Developing a virtual stiffness-damping system for airfoil aeroelasticity testing

Abstract

PSPB accepted the recommendations of an ad hoc committee, which reviewed the policy that had previously been revised in November 2010. The highlights of the current policy are as follows:  The policy reaffirms the principle that authors are free to post their own version of their IEEE periodical or conference articles on their personal Web sites, those of their employers, or their funding agencies for the purpose of meeting public availability requirements prescribed by their funding agencies. Authors may post their version of an article as accepted for publication in an IEEE periodical or conference proceedings. Posting of the final PDF, as published by IEEE Xplore®, continues to be prohibited, except for open-access journal articles supported by payment of an article processing charge (APC), whose authors may freely post the final version.  The policy provides that IEEE periodicals will make available to each author a preprint version of that person's article that includes the Digital Object Identifier, IEEE's copyright notice, and a notice showing the article has been accepted for publication.  The policy states that authors are allowed to post versions of their articles on approved third-party servers that are operated by not-for-profit organizations. Because IEEE policy provides that authors are free to follow public access mandates of government funding agencies, IEEE authors may follow requirements to deposit their accepted manuscripts in those government repositories.

Design of an Increased-Fidelity Aeroelastic Experiment for Wing Response to Gust Excitation

“…The platform could, in principle, also be actuated in closed-loop configuration to mimic linear or non-linear stiffness behaviour. Finally, Tang et al 17 developed a virtual stiffness-damping system to control the motion of a typical section airfoil. Instead of springs and dampers, actuators controlled in closed-loop configuration were used to provide stiffness and damping to the aeroelastic system.…”
