Review: key technologies for wide-body aircraft

Wide-body aircraft is the key technical product in the field of civil aviation. The development of wide-body aircraft is the important reflection of national comprehensive strength, as well as the inevitable course to achieve technological autonomy. This paper provides systematic review on the current status and future trend of key technologies for wide-body aircraft in the field of aerodynamics, structure, strength, power plant and main airborne systems, based on the analysis on global wide-body aircraft development. Key technological breakthroughs for wide-body aircraft will primarily focus on areas such as aerodynamic design of high aspect ratio wing with variable camber, nonlinear static aeroelastic design with large deformation, fly-by-wire control law design with more advanced functions, large-scale application of advanced composite structure, structural health monitoring, cockpit integrated warning systems, multi-mode and multi-orbit satellite communication and closed-loop attitude control in flight control systems, etc.
