Boeing has chosen Safran Electrical & Power to provide the electrical power generation system for the X-66 flight demonstrator it is manufacturing as part of NASA’s Sustainable Flight Demonstrator project. Announcing the selection on Tuesday, the company said it will also support ground and test flights for the transonic truss-braced wing concept aircraft due to begin in 2028.

The X-66 program is intended to pave the path toward possible next-generation single-aisle airliners to deliver technology leaps in fuel efficiency and reductions in emissions.
