    A Tribute to Mac by Herm RediessAerospace Control and Guidance Systems CommitteeMeeting 99Boulder, CoFebruary 27 March 2, 2007

  • Duane T. McRuer, Mac, an entrepreneur, scholar, humanitarian, conservationist, educator, author, and engineer who was instrumental in the development of aircraft flight control technology and the understanding of how people control vehicles of all types.

    Mentor and technical advisor to many of us in the aerospace business.

    My personal friend as he was to many others.

    Born October 25, 1925 in Bakersfield, California

    Died of prostate cancer January 24, 2007 at his home in Manhattan Beach, California.

    Survived by his wife Betty and daughter Lara.

  • Brief Professional BiographyServed as a Navy Lieutenant, JG, in WW II, developing anti-submarine technology1945 BS, 1948 - MSEE degree from CalTech1948 - Joined Northrop Aircraft, quickly became Chief of Flight ControlsLed flight control development of many aircraft, including the Northrop flying wing, F-89 and othersAmong the first to introduce artificial stability augmentation to aircraft - necessary for high-speed flightCoined the term Stability Augmentation System (SAS) when working on the flying wing (originally stability derivative augmentation system, but would not fit in the drawing box)First yaw damper SAS on the flying wing (as I recall)Leader of mathematical analysis of automatic and manual flight controlAuthored series of reference books sponsored by the Navy Bureau of Aeronautics, which later evolved to become the popular text Aircraft Dynamics and Automatic Control co-authored with Dunstan Graham and Irv AshkenasCo-authored Analysis of Nonlinear Control Systems with Dunstan GrahamHeld four patents in flight control

  • Brief Professional Biography (continued)1957 - Co-founded Systems Technology, Inc. (STI) with Irv AshkenasPresident and Technical Director until 1993, remained as Chairman of the BoardWorked directly or as consultant on many of the AF and Navy fighter aircraft and many commercial transportsBroadest knowledge of flight dynamics, pilot-in-the-loop,and automatic flight controls Principal contributor to theory of human operator control of vehicles (land, sea, under-sea and air) and mathematical modeling of man-machine systems STI documented the stability and control characteristics of many high-performance aircraft for NASA DrydenPioneer in Pilot Induced Oscillations (PIO) phenomenonFirst to understand and analyze X-15 later-directional PIO at high angle-of-attackAnalyzed PIOs on many aerospace vehicles, including the Space ShuttleAfter downturn in aerospace after the Apollo, broadened STI interests to vehicles, including cars, trucks, trailers, airships, submarines and tanksSTI researched and developed a remotely piloted, free-flying Pterodactyl for Smithsonian InstituteServed on the NASA Advisory Council and Chaired several Advisory Committees and SubcommitteesAdvisor on the Space Shuttle Flight Readiness Review Board
