A new research center has been funded by the AFOSR and the NASA Fundamental Aeronautics Program to study hypersonic combined cycle propulsion systems. The Center has identified three regimes of a TBCC as critical to the successful operation of the combined cycle system: the turbine to ramjet transition, the ramjet to scramjet (dual-mode) transition and the hypervelocity operating regime. Experiments will be conducted, using advanced flowfield diagnostics, in three separate Center facilities, to provide measurements to characterize these three flow regimes. Advanced models will be developed using data from the three experiments. The goal of the model development is to provide an advanced suite of computational tools for modeling the complex flow in hypersonic combined cycle propulsion systems.
