Lenta (citing Interfaks) says a source close to ODK General Director Vladislav Masalov says a PAK FA with the “second phase” engine will fly in 2017.
He reportedly said the “second phase” engine will replace “item 117″ and give PAK FA supercruise capability while being 15-18 percent more fuel efficient and cheaper to maintain.
New engines are further developments of AL-41f1 engines used in current Pak fa prototypes and will be able to generate afterburner thrust 176kn each.
