Here is an image of the X-59’s 13-foot General Electric F414 engine as the team prepares for a fit check. Making sure components, like the aircraft’s hydraulic lines, which help control functions like brakes or landing gear, and wiring of the engine, fit properly is essential to the aircraft’s safety. Once complete, the X-59 aircraft will demonstrate the ability to fly supersonic while reducing the loud sonic boom to a quiet sonic thump and help enable commercial supersonic air travel over land.
