MECHANICAL CONCEPT OF WHIRL FLUTTER AEROELASTIC DEMONSTRATOR


Abstract eng:
This paper deals with the design of the whirl flutter aeroelastic demonstrator. It gives a theoretical background of the whirl flutter phenomenon. The main part is focused on the new aeroelastic demonstrator "W-WING", designed at the VZLU. The demonstrator represents wing and engine nacelle of a twin turboprop commuter aircraft. It enables changes of the main structural parameters influencing whirl flutter stability characteristics. Moreover, it includes thrusting propeller. The demonstrator is intended for experimental investigations at the VZLU 3m-diameter low-speed wind tunnel. The results will be used for validation of analytical methods and software tools as well as in the frame of research projects.
