Prior to these special assignments, Dr. Stewart was Project Manager from 1986 to 1994 for several major projects at Dryden. He originated the F-15 Advance Control Technology for Integrated Vehicles (ACTIVE) Project, which included Pitch-Yaw Thrust Vectoring Control and Adaptive Intelligent Control Research. Prior to this, he was Project Manager for the F-15 Highly Integrated Digital Electronic Control Project (HIDEC), which included Adaptive Digital Engine Control (ADEC), Performance-Seeking Control (PSC), Propulsion Controlled Aircraft (PCA), and Self-Repairing Flight Control System (SRFC) Projects.
Dr. Stewart was the Project Engineer at NASA for the X-29 vehicle from 1982-1985, in which he was responsible for all engineering and flight test of the X-29 vehicle. Prior to 1982, he was Principal Investigator for the F-8 Digital Fly-by-Wire Projects at NASA including international research activities.
