NASA Glenn Hosts Engine Technology Workshop

Researchers from around the country, as well as local designers of industrial equipment, are meeting today to describe recent developments in turbine engine seals technology and to discuss the problems and issues that remain.

NASA's Glenn Research Center, Cleveland, Ohio, is hosting the two-day Seals and Secondary Airflow Workshop, which for each of the last nine years has brought more than fifty specialists to the Cleveland area.

Pushing the development of new turbine engine technologies is the desire for higher speed, greater fuel economy and lower noise. Whether those desires can be met in part depends on the effectiveness of the seals which separate one air flow passage from another inside the engine.

"Some people are surprised to learn that an improvement in aircraft or rocket engines could also be useful in industrial equipment," said Bruce Steinetz, Glenn researcher and workshop chair. "but seals and secondary flow management problems are pervasive and occur in pumps, compressors and other machinery with rotating parts, as well as in aircraft turbine and rocket engines."

In addition to aircraft and industrial turbine seals, the workshop will cover the computational analyses and computer programs that are being used to design seals, the seals development programs for space vehicles, and recent work at Glenn on aircraft materials and advanced sensors.
