Preliminary Investigation of Self-Excited Vibrations of Single Planing Surfaces. Technical Note 3698.

摘要

A preliminay investigation was made of self-excited vibration of single planing surfaces.A self-excited oscillation freedom in the rise but not in trim occurred with high aspect ration (order of 10) of the wetted portion. This vibration could be controlled most successfully by methods (such as the use of dead rise) which limited the wetted aspect ratio.
