This paper contains a brief description of the water-jet propulsion system as applied to hydrofoil craft, and a discussion of the salient hydrodynamic aspects of the problem of fitting the main propulsion system to the specified thrust-versus-speed requirements. The factors that affect the overall propulsive efficiency and the weight of the system are discussed at some length; procedures for optimization of performance at the design cruising speed are outlined; finally, the processes by which the performance at off-design conditions may be evaluated are discussed and illustrated with performance curves for one specific design.

Pump Speed

Based on characteristic of water jet, there are two important factors to product the thrust. One factor is pump speed and the other is the nozzle diameter. So, The significant optimization be required in order to overcome the existing water jet propulsion problem. In this paper, the water jet propulsion system model be studied at first, and then pump and nozzle optimization be discussed. At last, the result shows that the thrust of water jet by controlling the nozzle diameter size and pump speed.

Water Tightness

Manoeuvrability is one of the essential keys in the development of improved autonomous underwater vehicles for challenging missions. In the last years, more researches were dedicated to the development of new hulls shapes and thrusters to assure more manoeuvrability. The present review explores various enabling technologies used to implement the vectorial thrusters (VT), based on water-jet or propellers. The proposals are analysed in terms of added degrees of freedom, mechanisms, number of necessary actuators, water-tightness, electromagnetomechanical complexity, feasibility, etc. The usage of magnetic coupling thrusters (conventional or reconfigurable) is analysed in details since they can assure the development of competitive full waterproof reconfigurable thrusters, which is a frictionless, flexible, safe, and low-maintenance solution. The current limitations (as for instance the use of non conductive hull) are discussed and ideas are proposed for the improvement of this new generation of underwater thrusters, as extending the magnetic coupling usage to obtain a fully contactless vector thrust transmission.
