Modelling of some stealth features for a small navy ship at the concept design stage - part II

Szulist N.

Journal of Polish CIMAC

2014

Vol. 9, no 3

101--110

In the paper a few problems associated with modelling the basic stealth features for a small ship at the concept design stage are introduced. One problem concerns the modification of the immersed ship hull using the rapid change of the ship loading condition. The second is associated with the modification of the ship boundary layer by the hull skin cover. The other stealth features of the ship are not presented in this paper. The research method is based on the risk assessment and assessment of the ship performance. The risk may be estimated according to a proposed risk model. The risk assessment can be done according to the risk matrix criteria. The ship performance assessment is based on modification of the ship hull position on the water surface and modification of the ship boundary layer. Some elements of the research method and mathematical model for estimating the ship performance are introduced in the paper. Generally, the research is associated with the interdisciplinary investigations and multi-criteria ship design. The problems presented in the paper follow from the a Ph.D. research conducted at the Faculty of Ocean Engineering and Ship Technology Gdańsk University of Technology.
