Abstract
The AVT-331 Research Task Group studied the potential benefits of Multi-Fidelity (MF) methods in vehicle design and documented the relative strengths and weaknesses of different MF methods using a common benchmark suite developed by the team. Benchmarks were established at three levels of complexity for air and sea vehicles and two levels of complexity for a space vehicle configuration. The use of benchmarks at different levels of complexity enabled broad collaboration and knowledge exchange while critically testing method practicality. MF methods were generally found to provide cost benefit for tasks related to the exploration of vehicle parameter spaces or in the optimization of vehicle designs. Cost decrease of one order of magnitude was observed for the sea benchmarks and the intermediate-complexity air benchmark. Numerous opportunities exist for larger and more reliable cost savings through further method development, e.g., improved dimensionality reduction and gradient-based methods. Studies were conducted by 21 appointed team members from nine countries, along with several additional collaborators. The strong collaboration within AVT-331 and the research relevance of the task group’s activities are reflected by over 50 peer-reviewed articles, conference papers, and theses, many of which involve partnerships between AVT-331 members.
