Dr. John Lytle, chief of the Computing and Interdisciplinary Systems Office at NASA's Glenn Research Center, Cleveland, was recently honored for his outstanding leadership in the development of advanced software that is dramatically improving the engineering productivity in the design of propulsion systems for military and civil applications.

The American Institute of Aeronautics and Astronautics (AIAA) 2003 Information Systems Award was presented to Lytle for his personal leadership in the development of software such as the Numerical Propulsion Simulation System, which has enabled major changes in the modeling and simulation of aerospace propulsion and power systems.

The award was presented to Lytle during the awards luncheon of the AIAA Digital Avionics Conference in Indianapolis, Indiana. AIAA has been the principal organization for aerospace engineers and scientists for more than 70 years.

"Dr. Lytle is a valuable member of our aeronautics management team here at Glenn, and I am proud to see him honored," said Dr. Arun Sehra, director of Aeronautics at Glenn. Sehra added, "John's contributions will help to greatly reduce time and cost in developing propulsion systems for aeronautics and space."

In 1987, Lytle began his career at Glenn working for Sverdrup Technology, Inc. developing and validating computational fluid dynamics codes for hypersonic propulsion systems. He joined NASA in 1989 as a civil servant in the Turbomachinery Branch of the Internal Fluids Mechanics Division. In 1990, he was selected as Chief of the Methods Development Branch in the Aerospace Analysis Office.

Lytle received his bachelor's and master's degrees in mechanical engineering from The University of Dayton and his doctorate in aeronautics and astronautics from The Massachusetts Institute of Technology.

Currently, in addition to managing NASA's power and propulsion work under the Computing, Information and Communications Program, Lytle also manages the Engineering for Complex Systems Program to carry out research for reducing the risk of developing and operating complex systems through the use of advanced information technologies.
