Flutter Research and Design: Effects Upon the Designer of Some Results of Recent Flutter Research Available to Purchase

THE necessary manoeuvres of fighting aeroplanes in the present war may occasionally be expected to stress them beyond their strength. In addition to this, the increase in speed may be expected to produce unpleasant vibration. It is interesting, therefore, to consider how recent flutter investigations have influenced aeroplane design, and it is proposed in this article to review the more practical aspect of flutter research and to give a general guide to designers as to the importance of the many parameters influencing flutter speed.
