What is so great about AG600M
(1) One-in-a-million new airfoil design: the AG600 aircraft is a large subsonic aircraft. Due to the particularity of its mission, it must have good high-altitude cruise economy and excellent low-altitude and low-speed performance. For the high-lift and stall safety design goals of the aircraft, water take-off and landing performance improvement and reduce water landing load and other requirements, through comprehensive aerodynamic design optimization, the team achieved the stall characteristic control goal, shortened the take-off and landing distance of the aircraft, significantly improved the low-altitude and low-speed capability, and ensured aerodynamic safety.
Airfoil design is a key technology that needs to be broken through in aerodynamic optimization design. Based on the previous research, the design requirements of the airfoil were forwardly sorted, and at the same time, the advantages of the airfoil of similar models were absorbed, and a set of airfoil forward design process was established for the aerodynamic design requirements of large amphibious aircraft.
(2) Unique seaplane pressurized cabin: Adding a pressurized cabin to an amphibious aircraft is like putting the fuselage of a large airliner on a boat. In order to organically combine the upper pressurized fuselage section and the lower hull, the research and development team continued to tackle key problems and carry out program demonstrations, and finally determined a pressurized cabin solution suitable for large amphibious aircraft. The stress and complexity of the pressurized end frame of the AG600M aircraft is far more complex than that of civil aviation airliners of the same level, and the special-shaped pressurized cabin also faces the challenge of complex and changeable usage environments: Air-dropped water on the fire scenario, water rescue under severe sea conditions, fatigue damage under salt spray corrosion, etc. In order to ensure that the pressurized cabin scheme can stand the test, the development team repeatedly verified and carried out a lot of research and experiments, in order to pursue the design of "easy to use and effective" Kunlong.
(3) Advanced and safe fly-by-wire flight control system: AG600M adopts an advanced fly-by-wire flight control system, adopts a redundant architecture design, and adds functions such as control stability enhancement and flight envelope protection, established ground, water surface and airborne flight control rule. The flight control system can realize safe and worry-free flight under various environmental conditions and mission profiles, improve the flight quality of the aircraft, optimize the man-machine control interface, and greatly added to the systemic performance.
(4) Integrated avionics system with high system scalability: The avionics system of AG600M has undergone a system architecture upgrade and cockpit display man-machine control interface optimization, a domestically produced integrated modular avionics system was adopted, in addition to improvement of network topology and transmission bandwidth have also brought weight reduction of the wiring system, and the reconfigurable display screen specially designed for fire fighting missions and three-person crews has significantly improved the ergonomics of the aircraft during mission execution.
