NASA signs agreement with Rolls-Royce on braze joint technology testing

21 May 2014

The innovative technology partnerships office at NASA Goddard Space Flight Center in Greenbelt, Maryland said it has signed 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.

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.
