STABILITY AND MANEUVERABILITY OF A TAIL-FIN STABILIZED SUBMERSIBLE,
Abstract
An analytical investigation of the stability and maneuverability of a tail-fin stabilized submersible with sail appendage is accomplished using a linear model. The hull form used is based on the DSRV (Deep Submergence Rescue Vehicle). Configuration stability ranges are established from a Routh stability analysis in the frequency domain. The steady-state conditions of significant motion parameters for a large number of configurations within the stability ranges are calculated. The pitch and roll natural responses for various configurations is also analyzed. Vehicle motion is defined in two orthogonal maneuvering planes; the vertical and horizontal planes. The linearized equations of motion for each plane are expressed in state variable form, and discrete-time approximations of these equations are generated for computer simulation purposes. A correlation between optimum maneuverability in each plane is made, and a set of vehicle configurations for overall optimum performance is suggested. (Author)
