High-Speed Noninvasive Multi-Parameter Laser Diagnostics for High-Mach-Number Flows, Phase I

The proposed research program will develop an advanced laser-based, high-data-rate, multi-dimensional, multi-parameter, noninvasive optical diagnostic platform for NASA ground test facilities. Such diagnostic capabilities will be a major step forward in design and model validation efforts in supersonic and hypersonic ground test facilities developing next generation space vehicles and air-breathing propulsion systems. During the proposed program, we will develop these measurement tools into compact, user-friendly and mobile platforms enabling widespread implementation in ground test facilities as well as extended use in inflight test conditions. The expertise within this research team in state-of-the-art laser technologies, physics and chemistry-based diagnostic techniques, and extensive product development and implementation background in defense, propulsion and energy applications will be a critical factor in realizing the proposed diagnostic platform and toolkit. The advanced diagnostic toolkit proposed under the current program will be a significant step forward in utilizing cutting edge laser technology and spectroscopic approaches to address variety of diagnostics challenges in multiple government and industrial applications. A major beneficiary besides NASA would be DoD test facilities developing advanced weapons systems such as supersonic fighter aircrafts, hypersonic vehicles, rockets and high-Mach number reentry vehicles. In addition, fast developing commercial space industries as well as conventional aircraft manufacture's test facilities will significantly benefit by having access to such advanced diagnostic toolkits. Therefore, a wide market potential is expected in defense, industrial and commercial sectors for the proposed technologies. More »
