NEW CONCEPTS IN SHIP DIRECTIONAL CONTROL

A new propulsion system for ships has been discussed in Sheets (1978). This propulsion system provides a source of pressurized water between the pump and the turbine of the hydraulic transmission turbine. The water jet leaving the transmission turbine can be vectored by means of discharge vanes so that it is possible to greatly improve the directional controllability of ships. Several configurations are possible for the proposed control system, but at this time, only a single configuration is presented. The thrust force of the jet leaving the hydraulic transmission can be adjusted and modulated to meet requirements. For maximum ship control, the quantity of flow and power into the transmission can be increased compared to power transmitted to the propeller. This new control system should make it possible to reduce the size or eliminate ship control surfaces entirely, resulting in a small reduction of total drag and increase of ship speed.
