Mark Guynn

Title: Chief Engineer

Technical Focus Area: Aerospace Systems Analysis, Advanced Concept Development

Study Topics/Expertise: Air Vehicle Sizing and Performance Analysis, Aerodynamics

Mr. Guynn has spent over 30 years working in the areas of systems analysis and concept development. Prior to becoming Chief Engineer for SACD, Mr. Guynn served as their Chief Technologist and as Assistant Branch Head of the Aeronautics Systems Analysis Branch (ASAB). Previously he was the co-lead for Systems Analysis and Integration in the Advanced Air Transport Technology Project of NASA’s Aeronautics Research Mission Directorate. Mark started his career at NASA Langley as a co-op student and through the course of his career he has contributed to a diverse range of activities spanning High Altitude Long Endurance (HALE) scientific aircraft, fighter/attack aircraft, subsonic transports, supersonic transports, and planetary exploration aircraft.
