The systems for the AS2 are complex, but not a significant departure from current technology. For example, Airbus Group’s depth of experience in major systems architecture, especially fly-by-wire technology, is put to good use. The fuel system integrates with the flight control system because fuel is transferred to maintain weight and balance when transitioning between supersonic and subsonic flight. All systems—including avionics, environmental controls, hydraulics, auxiliary power, waste and water, and electrical—are in the process of being engineered, and systems suppliers are being assessed.
Systems routing in the aft fuselage is seen without surrounding airframe structure. An integrated product team works concurrently to avoid space conflicts when laying out systems.
Through successive design studies, the Airbus team is honing an articulating landing gear configuration that retracts neatly into a compact envelope within the fuselage. This economical use of space increases useable fuel volume and helps achieve weight and stiffness objectives for the wing box.
