Hydro-Structural Data-Driven MF-MDO of High-Speed Small Crafts via Multi-Loop Digital Design
Abstract
Approved for Public Release. The overall objective is to significantly extend the Cycle 1 Digital Design progress for hydro-structural data-driven MF-MDO of high-speed small craft via multi-loop Digital Design. The approach includes collaborations and progress on all aspects of the Digital Design process whereby #real world# design requirements and applications are used to demonstrate the basic research S&T developments and capabilities. The advanced concepts include novel hull forms and flexible plate slamming via collaborations with VT and UMD, respectively. The big & sparse data research feeds the ML&AI research which feeds the data driven MDO research all of which is accomplished via the integrated iterative Digital Design process. An important advancement is for the multi-loop MDO, which for a specified mission will provide options for best craft size, weight distribution and structure. A 3-loop process is envisaged. An external loop over (1) hull forms (L, B, T) with two internal loops over (2) weight distributions (LCG, VCG), and (3) structural arrangements. The process includes objectives and constraints based on the specified mission and other requirements. Design options will be selected for virtual trials. Support will be provided for Digital Design GUI development.
