Recently, a development of supersonic air vehicles using supersonic airbreathing propulsion system is active. In case of supersonic air vehicles, aerodynamic and thermal loads are caused by flight condition. To predict structure deformation caused by aerodynamic/thermal loads, necessity of fluid-thermal-structural analysis tool has been raised. However, at the initial design process, high-fidelity analysis tools have difficulties such as computing time and detail configuration.
In this study, based on supersonic vehicle with SCRAMjet propulsion system, development of low-fidelity aerodynamic analysis tool and verification with high-fidelity analysis tool establishes middle-fidelity and high fidelity aerodynamic analysis tool.
Using low-fidelity thermal analysis tool, structural analysis tool and structural optimization tool develops analysis process and tool for supersonic /hypersonic air vehicle. Then, derived the structural design using the analysis tool to verification analysis process.
