Dr. Song Wencong was the chief designer of the J-10 program and mentor to Yang Wei, who was in charge of both the JF-17 and the J-20. The paper I translated was a theoretical document written in 2001 discussing the aerodynamic considerations of a "future fighter". Hopefully my translation could shed some light on the role and design considerations of the J-20 fighter.
