Modeling, analysis, and uncertainty quantification of a lightweight torpedo design

In designing a lightweight torpedo, multiple performance criteria from many disciplines, including structures, acoustics, controls, and hydrodynamics, have to be satisfied in order to maintain a high probability of success for the mission. These criteria could conflict with each other as design requirements, in which case the final design will be the configuration that minimizes conflicts. Performance criteria depend on various design parameters that constitute the configuration of the torpedo and these are usually assigned deterministic values. However, in reality, the parameters would exhibit variations, and thus the design criteria could potentially violate the feasible design space. Therefore, this paper presents a robust torpedo design strategy that provides the designer insight into the safety of the final configuration, subject to variations in design parameters. In this paper a torpedo is modeled using finite elements and its static and dynamic characteristics are analyzed subject to variations in the design parameters structural problem.
