In subsequent years following the Challenger Disaster, I was tapped to perform failure modes and effects analyses and evaluation of malfunction procedures, as well as tracking project re-designs and Space Shuttle Robot Arm interfaces to Orbiter experiments. Provided recommendations to NASA program managers. Routinely worked with and modified very high resolution dynamic simulators to study the unique characteristics of the Shuttle carbon-composite manipulator boom and joint servo dynamics. Provided specifications, design calculations, design drawing supervision, cost and budget estimates, construction contractor bid evaluations, bid selection, and final construction quality inspections. Designed motor control centers with motors up to 250 horsepower for large process control plants.
