Safran to Provide Electrical Systems for Boeing's X-66 Flight Demonstrator

Safran Electrical & Power has been chosen by Boeing to supply the electrical power generation system for the X-66 flight demonstrator.

This initiative is part of NASA's Sustainable Flight Demonstrator project, which aims to advance technology for reducing carbon emissions in commercial aviation.

The Sustainable Flight Demonstrator is a component of NASA's broader Sustainable Flight National Partnership, focusing on achieving net-zero CO2 emissions. Boeing's X-66 program explores the Transonic Truss-Braced Wing (TTBW) concept, potentially enhancing fuel efficiency and lowering emissions in future single-aisle aircraft.

Safran's system features a variable frequency generator and a control unit, integrating advanced technologies. Designed for integration with the Pratt & Whitney GTF engine, the system provides over 100kW of electrical power. It is noted for its efficiency and reduced weight, cutting hydro-mechanical losses by nearly 50%, leading to fuel and emission savings.

Ground and flight tests are scheduled to begin in 2028, marking an important step in the development of sustainable aviation technologies.
