Technologically Improved Strengh of Critical Structural Elements of High-Speed Ships

Design and production of a new type of high-speed ship, named "Gliding wing", is a demanding task, due to its desired capabilities, complex structure, and hard operational conditions. It is necessary to apply new materials and include appropriate production technologies in a shipbuilding process. This paper suggest some of materials to be used for production of thinner components resulting in an overall lighter structure. Accordingly, appropriate surface treatement technology, shot-peening, is proposed to achieve a higher strength of "critical" structural elements. It is, also, shown that same technological process can improve fatigue strength of treated elements which is of great importance due to significant fatigue problem of considered structures.
