Specialty: Hypersonics/Aerodynamics and Propulsion
Email | Phone: (216) 433-5823

Dr. Blankson 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. In addition, as part of NASA’s Fundamental Aeronautics Program, has formulated and instituted a research program in plasma and MHD interactions in Aerodynamics and Propulsion.

Dr. Isaiah M. BlanksonDr. Christopher DellaCorte
Specialty: Tribology and Rotating Machinery
Email | Phone: (216) 433-6056

Dr. DellaCorte has applied expertise to lead complex root cause failure investigations with a successful, proven track record. Significant problem-solving accomplishments include deciphering the International Space Station (ISS) Solar Alpha Rotary Joint (SARJ) failure mechanism and recovery, guiding the rotordynamic analyses of the Mars Science Laboratory Surface Analysis on Mars vacuum pump bearing failure phenomena, understanding and advocating for re-lubrication of the Canadian Arm-Latching End Effector mechanism, and contributing to the Advanced Stirling Converter power fluctuation anomaly Red Team.

Dr. James A. DiCarloDr. James A. DiCarlo
Specialty: High Temperature Ceramics and Composites
Email | Phone: (216) 433-5514

Dr. DiCarlo has worked for over 35 years on the deformation and fracture mechanisms of structural materials. He has gained national and international recognition in the area of understanding and modeling the properties and time/temperature mechanical behavior of ceramic fibers and metal and ceramic matrix composites.

Dr. Marvin E. GoldsteinDr. Marvin E. Goldstein
Specialty: Aeronautics/Unsteady Fluid Mechanics/Turbulence
Email | Phone: (216) 433-5825
Dr. Goldstein served as the Chief Scientist at the NASA Glenn Research Center from 1980 to 2004. His technical accomplishments include a long list of “firsts,” including the development of an explanation for boundary layer receptivity to free stream disturbances, a rational analysis of oblique wave model interactions in shear layers, the theory for the so-called Klebanoff modes that are observed in boundary layers at high to moderate levels of free steam turbulence levels and an analytical solution for the problem of flutter in a cascade with strong in passage shock waves

Robert C. HendricksRobert C. Hendricks
Specialty: Seals/Fuels/Fluid Dynamics
Email | Phone: (216) 433-7505

Mr. Hendricks successful operation of the liquid oxygen (LOX) ammonia manned rated rocket engine turned to providing critical heat transfer design data for fluid hydrogen, now used in all LOX-hydrogen engines including the Space Shuttle Main Engine (SSME) and crew and cargo vehicle (J2 X,S) engines. For this work he received the NASA Medal for Exceptional Scientific Research. Work with cryogens hydrogen and oxygen led to the development of widely used thermo physical property codes GASP and WASP. Throughout the period, this work provided fundamental understanding to boiling, two-phase flows, supercritical and near-critical fluid behavior.

Dr. Meng-Sing LiouDr. Meng-Sing Liou
Specialty: Computational Fluid Dynamics, Multipahse Flow, Multidisciplinary Design Analysis and Optimization
Email | Phone: (216) 433-5855
Dr. Liou’s research has been primarily in fields related to fluid dynamics including his Master’s study in biomechanics at National Taiwan University and followed by the Ph.D. study in gas dynamics at the University of Michigan; both heavily involved methods of asymptotic analysis. His career in Computational Fluid Dynamics (CFD) has flourished in the enriching environment of the NASA Glenn Research Center.

Michael J. PattersonMichael J. Patterson
Specialty: Electric Thrusters & Propulsion Systems, Cathode and Plasma Sources, Plasma Physics Email | Phone: (216) 977-7481
Mr. Patterson has worked for over 25 years in the areas of electric propulsion thrusters and systems, and in development of cathodes and plasma sources for spaceflight and ground-based applications. His broad technical knowledge of propulsion system technologies and ability to implement and direct complex programs has lead to flight applications – from conception to on-orbit operations. His projects have included development of the Deep Space 1 thruster, the development of cathode technology for the International Space Station plasma contactor charge-control system, and development of the Next Generation Evolutionary Xenon Thruster (NEXT) ion propulsion system.

Dr. Louis A. PovinelliDr. Louis A. Povinelli
Specialty: Propulsion Systems
Email | Phone: (216) 433-5818

Dr.Povinelli’s professional accomplishments have contributed to the advancement of aeronautics and astronautics in several areas including air breathing propulsion, scramjet propulsion, rocket propulsion and pulse detonation engines. His activities at NASA Glenn involved research on turbine aerodynamics, inlets, diffusers, mixers and nozzles, turbomachinery, CFD validation, scramjet fuel injection, hypersonic propulsion systems and rocket combustion instability and real gas effects in pulse detonation cycles.
