Adamczyk Garners Awards for Aircraft Engine work

John J. Adamczyk, senior research scientist at the NASA Glenn Research Center, Cleveland, OH, has received recognition from three engineering societies for his work to improve aircraft engine design and performance.

The American Institute of Aeronautics and Astronautics announced that Adamczyk has won the Institute of Aeronautics and Astronautics Air Breathing Propulsion Award for 2001. The society cited him for outstanding contributions in the use of turbomachinery flow modeling for turbine engine design, which have resulted in major reductions in turbine engine development time and cost.

The American Society of Mechanical Engineers announced in its ASME News that Adamczyk has been elected to the member status of fellow, the highest grade of membership in the society. The society bestows this status on those who have made exceptional engineering contributions to the profession.

The International Gas Turbine Institute selected Adamczyk to receive the 2001 IGTI Aircraft Engine Technology Award for his sustained contributions to aircraft gas turbine engine technology. In 1999 he earned the institute's Scholar Award.

The AIAA award will be presented on July 11th at the Joint Propulsion Conference in Salt Lake City, UT. The ASME and IGTI awards were presented on June 4 at the ASME's Turbo Expo conference in New Orleans, LA.

Adamczyk has been actively involved in the analysis and mathematical modeling of turbomachinery (the rows of turbine blades inside a jet engine) flows since 1966. Two of his analyses from his early work are widely used within NASA and in industry. Since 1984, he has focused his work on the analysis of the flow within multistage engines and the development of his Average Passage model. The model is being incorporated into the design systems of several gas turbine engine manufacturers, and its use has resulted in significant performance improvements in the engines designed with it.

Adamczyk, of North Olmsted, OH, holds a Ph. D. in applied mechanics from the University of Connecticut and has been a member of the Glenn staff since 1975.
