FLUTTER OF A RING OF PANELS,

Pagination or Media Count:
A theoretical investigation was made on the flutter of a grid of panels in a supersonic flow. The problem is formulated by considering this structure as a limiting case of a more general configuration composed of a ring of panels i.e. an axially stiffened cylindrical shell whose outer surface is exposed to a supersonic flow parallel to its axis. It is shown that the flutter analysis of this more general configuration can be reduced to the analysis of an equivalent single panel using the circulant matrix idea. The reduction procedure, applicable to most cyclic configurations, allows for all types of inter-element panel coupling and is subject to the sole restriction that the dynamic phenomenon be satisfactorily described by linear theory.
