Fish Locomotion for Innovative Marine Propulsion Systems
There is an essential need for obtaining the mathematical representation of fish body undulations, which can be used for designing and building new innovative types of marine propulsion systems with less environmental impact. This research work presents a case study to derive the mathematical model for fish body movement. Observation and capturing image methods were used in this study in order ...
متن کاملMathematical Modelling of Diesel-Electric Propulsion Systems for Marine Vessels
This article presents a mathematical model of a complete diesel-electric propulsion system, including components as diesel generators, distribution network, variable speed thruster-drives, and conventional motor loads. The model is split into two parts: One power generating part where the load is speci®ed with an aggregated active and reactive power load demand. Secondly, a power consumption pa...
متن کاملResistance of Idle Propellers in Marine Multi-propeller Propulsion Systems
The configuration of a marine propulsion system is selected with regard to the maximum power resulting from its maximum design speed and displacement. The propulsion systems of high speed vessels use three or even four propellers, and each propulsion unit may be multi-engine. High speed vessels are designed for maximum speeds, but their factual exploitation speed parameters are usually consider...
متن کاملScreening of Slow Speed Marine Diesel Propulsion Shafting Design Space
Original scientific paper In this paper a systematic exploration of a typical two-stroke slow speed marine diesel propulsion shafting design space is performed. First, a set of the four most influential design parameters is defined, consisting of shafting stiffness, propeller, turning wheel and tuning wheel mass moments of inertia. Then, a full set of 625 design points is defined. For each desi...
متن کاملDesign Methodology Based on H∞ Control Theory for Marine Propulsion System with Bumpless Transfer Function
In this paper we propose a control system design methodology which has two main objectives: the first one is to achieve control system specifications for a local H∞ controller designed for a given operation condition, and the second objective is to provide a procedure for bumpless transfer (BLT) when the controller is switched to another one, due to change in the operation condition, or when th...
