Supersonic combustion is a vital, application-driven field of research, occurring in supersonic ramjets (scramjets) and rocket engine devices. The extreme operating conditions of these applications, such as Mach 4 through 7 for scramjets, and ambient vacuum, for rocket engine ignition, make ground-based experimental measurements very expensive and difficult. The use of computational fluid dynamics (CFD) could potentially play a vital role as an important complement or a substitute for experiments. Therefore, TTC''''s proposed high fidelity scramjet combustion software will add significant value to realistic scramjet design and performance analysis, with high accuracy and fast turnaround time. Moreover, the nature of the proposed software is such that its marketing synergizes with that of TTCs other software products, including its flagship CFD tool, AEROFLO. Both government and private sectors will find the proposed software to be very valuable. DOD and the National Aeronautics and Space Administration (NASA) will find it beneficial for their various projects on hypersonic air vehicle concept screening. The expected accuracy and robustness of the procedure also assures reduced time, risk and cost for commercial development of hypersonic propulsion capability for access to space using hydrocarbon fuels. The software modules could be licensed or sold to providers of analysis tools.
