NASA partners with Rolls-Royce on braze joint technology testing

The Innovative Technology Partnerships Office or ITPO at NASA Goddard Space Flight Center in Greenbelt, Md., has announced 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 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 Rolls-Royce.”

“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.
