Dr. Isaiah M. Blankson is a Senior Scientist/Technologist (ST) in the Research and Technology Directorate at NASA Glenn Research Center, Cleveland, Ohio.He has held this position since 1997, and serves primarily as a Hypersonics Specialist: Air-breathing Hypersonic Technologies.As an ST, he initiates and conducts research related to aeronautical and space propulsion systems, identifies research opportunities and defines research objectives, assists/advises in developing program goals, and provides leadership and teaching to staff in specialty areas.
He provides advice and guidance to NASA Glenn Administration, Center program managers, and other Government Agencies in his areas of expertise. Specialty areas include air-breathing hypersonic aerodynamics and propulsion, plasmas and electromagnetic interactions in gas dynamics, magnetic levitation systems, and advanced millimeter-wave imaging technologies for aviation safety and homeland security.
Recently, as part of NASA’s Fundamental Aeronautics Program, Dr. Blankson has formulated and instituted a research program in plasma and MHD interactions in Aerodynamics and Propulsion. He has assembled a team of six scientists and engineers to study topics in localized plasma flow control, plasma ignition and flame-holding, and alleviation of performance degradation in nozzles in the transonic regime.The team is also studying airframe/propulsion technology integration for hypersonic waveriders.
Dr. Blankson previously served as the NASA Program Manager, NASA’s Generic Hypersonics Program, NASA Office of Aeronautics (Code R), Headquarters, Washington DC(1988 -1996). The NASA-wide Generic Hypersonic research program, a $28 million per year program, was a fundamental program that addressed R&D primarily associated with air-breathing hypersonic vehicles that use highly-integrated airframe/propulsion systems.
As overall Program manager he was responsible for the planning, direction, review, and resource allocation. He also served as an Assistant Director, National Aerospace Plane Office (Code RN). In 1991, he was appointed Deputy Director of Hypersonics Research Division (Code R), NASA Headquarters. He is credited with laying the foundation for the SWERVE-PEGASUS program which eventually became the X-43.
Collaborating with military researchers (U.S. NAVY), he investigated the design of waverider cruise missiles and aircraft concepts that can travel at between four and eight times the speed of sound. He also came up with an innovative strategy to develop smart, long-range hypersonic cruise missiles powered by air-breathing, hydrocarbon-fueled engines. The U.S. NAVY’s RATTLRS program is one outgrowth of these efforts.
Dr. Blankson came to NASA from the General Electric (GE) Corporate Research Center in New York, where he probed the mysteries of hypervelocity plasma-armature projectile launchers, develop a gas-dynamic design for high-power circuit breakers, and parsed the gas-dynamics of high-temperature powder coating operations for halogen lamps.
Dr. Blankson earned all his degrees from the Department of Aeronautics and Astronautics at the Massachusetts Institute of Technology (MIT). He received the Bachelor of Science degree in Aeronautics and Astronautics in 1969, and the Master of Science Degree in Aeronautics and Astronautics in 1970. The Doctor of Philosophy (PhD) degree, also in Aeronautics and Astronautics, was awarded in 1973 for a thesis dealing with the interference-free wake of a magnetically suspended cone in hypersonic flow (Mach 6.3). At MIT, he was the recipient of the Luis de Florez Award for excellence in engineering.
Dr. Blankson’s current research is in the area of hypersonic aerodynamics and propulsion including waveriders, unmanned autonomous high speed air vehicles, weakly ionized plasma phenomena with application to drag reduction and sonic boom alleviation, and passive millimeter wave imaging applied to aviation safety problems. Specifically, Dr. Blankson is actively pursuing studies in the following areas:
MHD Energy Bypass Engine Concepts (Mach 0-7) based on conventional and exoskeletal gas turbine engines. Applications are to global-range cruise vehicles, two-Stage Space Access vehicles, and energy-on-demand hypersonic systems.
Weakly-Ionized Plasma (WIG) phenomena – aerodynamic and propulsion applications of WIG. (Electromagnetic Field interactions in hypersonic flows). Applications are to supersonic and hypersonic flow control, wave drag reduction, and sonic boom alleviation.
Airbreathing Hypersonic Cruise: WAVERIDER AIRCRAFT and CRUISE MISSILES. Airframe-integrated Mach 4-7 Hydrocarbon – fueled waverider aircraft/missiles, advanced waverider design concepts (inverse design methods). The emphasis is on unmanned autonomous high speed air vehicles: especially supersonic and hypersonic cruise missiles and UCAVS concepts using turbo ramjets.
Application of Magnetic Levitation Technologies to Propulsion, e.g. Magnetically Levitated Composite Fan as an emission-free component of an all-electric engine.
Passive Millimeter Wave Imaging: Application to aviation safety problems: Development of 35GHz and 95GHz passive cameras with the ability to see through fog, and detect concealed weapons. Application to navigational aids for aircraft landing and takeoff, and the imaging of launch vehicles through their exhaust are other areas of pursuit.
