Extract

The theme of flutter has not often been the subject of lectures before this Society, but the earliest of these was given as long ago as 1929 by my friend and former colleague Dr. R. A. Frazer. At that time a secure foundation for flutter theory had been laid and the principal methods for flutter prevention were already known. However, both theory and practice have developed much since 1929 and flutter has become of greater relative importance.
