Dr. Richard G. Cobb
Professor Emeritus of Aerospace Engineering
Dr. Richard G. Cobb is a Professor Emeritus of Aerospace Engineering in the Department of Aeronautical and Astronautical Engineering with over 35 years of aerospace experience. Over the past, 18 years at AFIT, he has taught graduate level courses in satellite design, optimal control, trajectory optimization, system identification and spacecraft control systems. He teaches courses on classical, robust, and optimal control theory, trajectory optimization, and satellite design. His research focuses on dynamics and control of aerospace systems, including control of aircraft, spacecraft, large flexible structures, and optical systems. Recent work includes developing optimal trajectory plans for Global Strike missions, optimal aircraft air and ground collision avoidance algorithms for manned and unmanned systems, active buffet alleviation using piezoelectric actuators for F-16 aircraft, maneuver planning for satellite proximity operations, dynamics and control techniques for lightweight space optics and optimal/novel sensor systems and architectures for enhancing Space Situational Awareness.
While on active duty, Dr Cobb served as the technical advisor for AFRL’s Space Vehicles Technology Branch, and has led several space flight experiment programs, including the Vibration Isolation and Suppression System sponsored by BMDO, and the Satellite Ultra-quiet Isolation Technology Experiment. Dr. Cobb also served as a launch operations officer at Cape Canaveral AFS on the Global Positioning System program, responsible for the integration and launch of the GPS Block II satellite constellation.
