Unit Cases to Investigate Hypersonic Fluid Structure Interaction
Abstract
We will design a new group of unit cases for hypersonic fluid structure interaction (FSI) and use these to perform new, first of kind experiments to measure complex fluid structure interaction in hypersonic flows on fundamental configurations of relevance to hypersonic vehicles. We will use this data to assess and improve advanced numerical simulation tools, and make these experimental data sets available to the wider FSI community. This experimental and numerical data will in turn be used to reveal the underlying physics of the fluid structure interactions and establish the relative significance of the driving parameters. Accurate prediction of the behavior and lifetime of structural components subject to these fluid structural interactions, in which the deformation of the structure induced by the local flow field, can in turn influence this flow field, is critical. This coupling can result in damage to a hypersonic vehicle or even catastrophic structural failure and thus robust design tools must be developed to avoid this while maintaining efficiency of structural mass. This work will contribute to the improvement of the accuracy of simulation tools that are urgently required to aid industry in the design of more structurally efficient and robust high speed vehicles. Robust designs are necessary to ensure the safe, optimal and economic operation of these vehicles for applications from strike and intercept to high speed transport, to space access.
