Abstract:

In writing the equations for pitching motion of a submarine in submerged operation it has been customary to neglect the effect of metacentric stability. Recent operating experience at moderate speeds of the order of 10 knots has indicated, however, that this simplification does not adequately represent the behavior of the submarine for such speeds. In the present paper the equations of longitudinal motion have been written to include the effect of metacentric stability and these extended equations have been used in an analysis of the effect of metacentric stability on the pitching characteristics of a typical submarine operating at various speeds.
