Evolutionary optimization of ship propulsion systems

The concept of a linear jet yields the potential to play a decisive role in modern ship propulsion systems technology. A linear jet consists of multiple components, namely a rotor, a stator, and a nozzle. The optimization of a complete linear jet is a complex and challenging task, which requires a couple of comprehensive simulation tools to work together. All required analysis and simulation issues are subject to ongoing research. The aspired optimization algorithm is already available and can be tested on the different components that can already be analyzed. In this way, the optimization is first limited to the propeller blade to determine good parameterizations for the optimization method. The results are analyzed in detail performing deeper investigations with additional optimization runs. Furthermore, one parameterization identified to perform best results is incorporated for the optimization of a complete propulsion system featuring rotor, hub, and nozzle.
