SF.60.21.B10047: Development of the Aero-Optic Measurements for Hypersonic Ground Testing: Methodologies and Characterization

McManamen, Brianne - 301-294-2019

EDC Hypervelocity Wind Tunnel 9* provides unique ground test capability that is currently in high demand for development of next generation advanced hypersonic interceptors. An effort to renew the capability of making aero-optical measurements in relevant environments for hypersonic interceptor seekers at Tunnel 9 is currently underway. Previous aero-optic measurements were performed in early 2000s at Tunnel 9 in a Mach 7 environment, references (1-4). Since then, significant advancements in high speed imaging, high speed laser sources, and understanding of aero-optic effects have been made. The goal of this renewed effort is to build an aero-optic measurement system that will allow for high resolution wave-front imaging and analysis, which can be deployed at Mach numbers ranging 7-18 for various advanced geometries and line-of-sight or look angles approaching zero, which incorporates the recent advancements in the aero-optic field. The desired research program would investigate new techniques for aero-optic measurements and data analysis that meet the unique challenges of the Tunnel 9 facility and NDS priority goals, which could include:
• Investigation of sources that can generate low look angles and how these can be implemented into tunnel 9 facility (laser induced breakdown, FLEET, fiber optics)
• Development of wave front analysis methodologies to address the decoupling of measured aero-optic effects into the facility generated effects and the quantities of interest for seeker development
• Investigation of aero-optic measurement techniques and best practices that improve wave front data obtained in ground test facilities such as Tunnel 9
• Characterization/calibration of aero-optic measurement system

*This research will be completed onsite at Wind Tunnel 9 located at White Oak Operating Location; Silver Spring, Maryland.
