A Scramjet/Ramjet Heat Exchanger Analysis Tool (SRHEAT™) has been developed for rapid analyses of complex thermal cooling systems. Thermal management is critical to the development of dual-mode scramjets for hypersonic aerospace propulsion, which have high thermal loading with limited availability of heat sink sources. It is necessary that rapid trade studies of the thermal management system be accomplished to optimize the system for weight and cooling efficiency. To meet this need, SPIRITECH has developed a scramjet/ramjet heat exchanger design and optimization tool that performs a thermal analysis of the heat exchanger, assesses its structural strength, and optimizes the heat exchanger design to minimize the cooling flow requirement and the heat exchanger weight. FuelDev™ has been developed as an add-on to SRHEAT™ to provide a system level tool allowing fuels developers to experiment with fuel databases and to perform “what if” scenarios to determine the system level impacts of changes in fuel properties. FuelDev™ provides a tool to compare and contrast existing fuels for use in hypersonic vehicle thermal management systems. This tool provides the user with the ability to quantify the sensitivity of the thermal management system to changes in fuel properties afforded by new fuel technologies. The detailed heat exchanger design features included in the tools (i.e. geometry, material properties, fuel/coolant properties, etc.) make SRHEAT™ and FuelDev™ a valuable suite of tools in scramjet and hypersonic vehicle development, providing the low cost analytical capabilities that make possible the efficient development of aerospace components and fuels. |
