GREENBELT, Md., May 20, 2014 /PRNewswire-USNewswire/ -- The Innovative
Technology Partnerships Office or ITPO at NASA Goddard Space Flight Center in
Greenbelt, Maryland is pleased to announce the signing of a Reimbursable Space
Act Agreement between Rolls-Royce, Indianapolis, Ind., to collaborate on the
development of braze joint performance prediction methods for critical
structures subjected to complex loading conditions.

Through this partnership Rolls-Royce will establish a braze Failure Assessment
Diagram (FAD) that can be used to define acceptable stress combinations and
margins of safety of braze joints and braze repair structures. NASA will
receive verification of its FAD methodology for failure prediction of
structural brazed joints on real industrial applications.

Rolls-Royce will use the "Methodology of Evaluating Margins of Safety in
Critical Brazed Joints," developed at Goddard by Dr. Yury Flom to help in the
performance prediction of brazed joints at NASA Goddard.

"I hope that recognition of this methodology by one of the leading aerospace
companies such as Rolls-Royce will help to improve our ability to design and
build more reliable critical brazing structures," stated Dr. Flom. "Critical
brazed structures are structural components in spacecraft, jet engines, power
generators, nuclear power generation systems, automobiles, medical devices
such as implants, pace makers, etc. Failure of such components could cause
multimillion dollar losses of equipment and possibly human lives."

The automotive and aircraft industry may benefit from this technology as it
could be used to design and manufacture components for use in automobile
radiators and space radiators, aluminum engine blocks and pistons, heat
exchangers for gas-turbine applications, all-metal honeycomb sandwich panels
for fabrication of aircraft structures, jet engines in commercial and military
aircrafts, thrust chambers in rocket engines; and for other electronic
components, probes and thermionic devices, space vehicle assemblies and
various miscellaneous applications.

"This fundamental research between Rolls-Royce and NASA will further enhance
the brazing technology for the joining and repair of gas turbine engine
components in aerospace applications," says Dr. Ray Xu, Senior Specialist at

"This agreement with Rolls-Royce offers a fantastic opportunity for NASA
Goddard to partner with an organization that has a wide-range of unique
research and development activities," said Dennis Small, Technology Transfer
Manager in NASA Goddard's ITPO.
