Bob's Résumé


California State Polytechnic College, BSME, 1959. 

San Diego State University, MSME, 1971. 


1978 to 2006 - Technical Staff Engineer, Mechanical Engineering Laboratory, Motorola GED & General Dynamics C4S. Consulted with project personnel in the areas of mechanical design, analysis, instrumentation and test.  Able to focus a wide range of interdisciplinary skills on a systems solution and get things done with a hands-on approach. Conversant with solid modeling, kinematic synthesis and finite element computer tools, and able to program custom numerical simulations that exceed the scope of canned routines.

1971 to 1978 - Mechanical Engineer, Richland Energy Laboratory, McDonnell Douglas.  Designed and developed hydraulic actuator and control sub-modules employed in artificial heart energy conversion systems.

1965 to 1971 - Mechanical Engineer, Design Section, Douglas Aerophysics Laboratory, McDonnell Douglas.  Designed custom fast-response/acceleration-insensitive force and pressure measurement transducers.

1965 to 1965 - Contract Engineer on assignment to Douglas Aircraft, Frank Mayer Engineering.  Performed heat transfer analysis of the Saturn S-IVB engine chill down process.

1963 to 1964 - Teaching Assistant and Research Assistant, San Diego State University.  Taught engineering graphics. Designed and fabricated a mechanical fluid-sloshing analog.

1962 to 1964 - Mechanical Engineer, Advanced Design Group, Rocketdyne Space Engines Division.  Researched and designed small liquid propellant propulsion systems.

1960 to 1962 - Design Engineer, University of Southern California Engineering Center.  Designed wind tunnel facility hardware, model support systems and force balances.

1959 to 1960 - Combat Engineer, U. S. Army Reserve.  Active duty training.
