Overview The overall goal of this project is a challenge presented by NASA; the challenge is to design an ultra efficient commercial transport for 2045 with the potential to surpass 30%-60% reduction of energy. The basis for comparison of the X-JAB is a 2005 best-in-class aircraft, we have chosen the Boeing 747 -400 as the basis for our aircraft. The overall task of this challenge is to achieve a dramatic reduction in energy consumption through innovative airframe and propulsion systems, new approaches to integration of the airframe and propulsion systems, and new operational paradigms.
