Iowa State alum Stephen Paris (BSAerE’75, MSAerE’77), technical fellow with Boeing’s research and technology division in Seattle, Washington, joins an elite group of engineers and scientists as the recipient of a 2009 R&D 100 Award. The awards, presented by R&D magazine annually since 1963, salute the 100 most technologically significant products introduced into the marketplace over the past year. Paris, along with team members from NASA Glenn Research Center, developed the software tool, Optimal Trajectories by Implicit Simulation, version 4 (OTIS4). It can be used to perform trajectory optimization and performance studies for a wide variety of vehicles including aircraft, rockets, satellites, and interplanetary vehicles. The team also won the 2008 NASA Software of the Year Award, which was presented in February 2009.
