Statement of work (SOW) - task title: hypervelocity mixing project 1.0 introduction/background: the propulsion discipline of the NASA hypersonics project has initiated a new research project to investigate the injection and mixing of fuel and air for scramjet engines at hypervelocity flight speeds (generally considered mach 10 and greater). This research project will enhance our understanding of scramjet injection and mixing devices and will provide a controlled test environment to evaluate innovative ideas. One of the milestones for the hypersonics project is to develop an air-breathing combined cycle space launch vehicle. To achieve this milestone, a scramjet engine which can operate at hypervelocity flight speeds is critical. Since the scramjet mixing and combustion processes are known to have the greatest potential for improving scramjet engine performance and efficiency, this research project is intended to provide a major step towards reaching the hypersonics project milestone. The hypervelocity mixing project, which is scheduled to begin in FY12, will involve ground-based experiments in the NASA langley research center (larc) ARC-heated scramjet test facility (ahstf). Candidate injector concepts will be fabricated at langley using the selective laser melting process and will be mounted to a common plate in the test facility. Flowfield measurements will be made using laser-based optical diagnostics and with in-stream pressure and gas sampling rakes positioned downstream of the injector hardware. The expected outcome of the hypervelocity mixing project is high-speed injectors that significantly improve scramjet performance (i.e., faster mixing with decreased drag) in the hypervelocity speed range. This task order is intended to provide design and fabrication support of the major hardware components necessary to successfully complete the goals of this project. 2.0 scope / objective(s): the scope of this task order is to obtain the design, analysis, fabrication, and manufacturing schedules of the hardware necessary to test and evaluate various fuel injection devices that will be tested in the langley ahstf. The objectives of this task order are to: 1) obtain detailed engineering designs, analysis, and engineering drawings of the test hardware. 2) delivery of test hardware.
