Farnborough, July 23, 2024:
Safran Electrical & Power has been selected by Boeing to provide the electrical power generation system for the X-66 flight demonstrator, part of NASA’s Sustainable Flight Demonstrator project. Safran Electrical & Power will also support ground and flight tests, slated to start in 2028.
The Sustainable Flight Demonstrator is part of NASA’s broader Sustainable Flight National Partnership, which is dedicated to developing the technologies needed to achieve net-zero CO2 emissions for commercial aviation. Boeing’s X-66 program is focused on developing the Transonic Truss-Braced Wing (TTBW) concept, which could enable significant improvements in fuel efficiency and reduced emissions for future single-aisle aircraft.
This electrical power generation system consists of a variable frequency generator and its associated control unit, integrating the most advanced technologies developed by Safran Electrical & Power. It has been adapted to integrate directly on the Pratt & Whitney GTF engine and provides more than 100kW of electrical power. This modern system features an unmatched weight and efficiency, and enables a reduction in hydro-mechanical losses of close to 50%, resulting in significant fuel burn and carbon emission savings.
“We are very honored to further expand our thriving partnership with Boeing under this NASA program, and to develop breakthrough technologies for the Sustainable Flight Demonstrator. Safran Electrical & Power is thrilled to be collaborating with Boeing, NASA and other industry partners to drive innovations and to embrace latest advancements in technologies aiming to achieve our industry-wide goal of zero-emissions,” said Bruno Bellanger, executive vice president of Power division at Safran Electrical & Power.
