D. Working To Improve Airplane Safety

Narrator: This is Science Today. Improving flight safety is the goal of researchers at the Lawrence Livermore National Laboratory. The group, along with three other companies, are working to develop a new standard tool to assist the Federal Aviation Administration in certifying the safety of new aircraft engines. Richard Couch, a lab physicist says this tool, a computer code program, would test rare but potentially devastating events.

Couch: Essentially a loss of a blade - a fan blade or a turbine blade or some sort of catastrophic failure of the engine which might send projectiles shooting off at the aircraft.

Narrator: Researchers are working to enhance a well-known simulation tool developed at the Livermore Lab, called the DYNA3-D.

Couch: What we're trying to provide a modeling capability for is containment of fragments within the engine. Or if fragments aren't contained, trying to model the impact on fuselage and to damage that might ensue from an individual event.

Narrator: It's hoped the tool will be available nationwide by the year 2000. For Science Today, I'm Larissa Branin.
