AG600 is developed with the work style of "Serving the Country by Aviation and Strengthening the Country".
The R&D team overcame multiple adverse effects such as high temperatures, the impact of the epidemic, and severe weather of typhoons, made overall planning, fine management, identified risk points in advance, scientifically scheduled production, and steadily promoted various tasks. With the perseverance of seizing the day and persevering, we have successfully defended all major nodes, and practiced the solemn commitment of "not letting the train be late at the door of the house" and the "Kunlong spirit" of "lofty aspirations, hard work and dedication, independent innovation, and dreaming of the sea and sky" with practical actions.
The AG600M aircraft demonstrated the 12-ton water dropping function at the 14th China (Zhuhai) Airshow.
On November 8, 2022, the all-new Kunlong AG600M aircraft optimized based on the technical demonstrator made a stunning appearance at the opening ceremony of the 14th China (Zhuhai) Airshow, demonstrating the 12-ton water pumping function to the public. Subsequently, the Aviation Industry Group announced to the public that the AG600M aircraft will be put into combat use after June 2023.
From 2012 to 2022, the AG600M Zhuhai Air Show was fully equipped with 12 tons of water pumping, during which the technical verification machine was born, and three first flights, the first flight of the all-state new configuration fire extinguisher and the demonstration of the water throwing function were completed. Over the past 10 years, the development of AG600 has consciously transformed the encouragement and ardent expectations of the party and the state into a strong driving force to promote various tasks, deeply implemented the innovation-driven development strategy, and experienced the shortening of the history of the development cycle of domestic large-scale new research aircraft, the filling of a number of technical gaps, and the win-win situation of "main contractor-first-class business" and "small core, big collaboration" and other innovations, the development of AG600 project has entered the fast lane of high-quality development. The development of the "Kunlong" AG600 has broken the situation that there are no new models in the ranks of amphibious special aircraft for many years.
Adhere to independent innovation
In 2008, the "5.12" Wenchuan University and the subsequent frequent occurrence of ice and snow disasters, forest fires and marine accidents in the south have exposed the small number and type of aviation equipment in the emergency rescue system.
First, the structure is unreasonable and other problems, the "National Aviation Emergency Rescue System Planning" was immediately promulgated, in order to meet the needs of forest fire fighting and water rescue - large amphibious aircraft AG600 began to be developed.
In accordance with the design idea of "amphibious, one aircraft with multiple types, and series development", the AG600 aircraft adopts a single-hull, single-wing layout on a cantilever and a retractable landing gear at the first three points, with more than 50,000 structures, more than 20,000 system parts, and more than 100,000 standard parts. The development of such a large special aircraft that can take off and land on land as well as on the water is rare in the world. With the advancement of model scientific research and flight test work, the domestic technical reserves are insufficient, the research and development funds are tight, and the development history gap makes the model have no experience to learn from, coupled with the aircraft weight, rescue radius, stall characteristics and other problems, all of which are mainly used for low-altitude and low-speed state to perform fire extinguishing tasks and search and rescue missions of the AG600 to form a challenge.
AG600M aircraft water drop.
The problems existing in the project gradually emerged, and the development team also accelerated the pace.
The scheme is designed in a round, countless large-scale tests, equipment safety tests, airworthiness review meetings, manufacturing compliance inspection procedures, first-class instructions, and the difficulties and obstacles encountered are numerous. The key technology of air-hydrodynamic layout has developed the world's tallest and most complex retractable landing gearIt solves the problems of manufacturing complex ship-type fuselage and gas-tight and watertight riveting, and preliminarily establishes a large-scale amphibious aircraft technology and manufacturing standard systemThe airworthiness verification and certification of AG600 aircraft has also greatly improved the level of airworthiness compliance verification of domestic civil aircraft, effectively promoted the soundness and perfection of the airworthiness system of civil aircraft, cultivated a professional team of appointed representatives for the civil aircraft development industry, filled the gap in the technical system of large amphibious aircraft and special airworthiness clauses, and opened a new era of AG600.
The AG600M aircraft demonstrates the emergency rescue and fire extinguishing function.
The AG600 technical verification machine has successively achieved the first flight on land, water and sea, as well as the verification test flight of the 12-ton water extinguishing function in all states.
It can be used, easy to use, and used early
With the goal of developing a usable, easy-to-use, and early-use aircraft, the R&D team carried out in-depth research on the market and user fire extinguishing and rescue use modes, and carried out the improvement and optimization technology demonstration work in combination with the problems existing in the early development.
On the one hand, it follows the forward design process, comprehensively sorts out the top-level design inputs, and identifies key design requirements such as aircraft maneuverability based on mission use scenarios and operational technical characteristics. In the midsummer of 2018, the marketing team of South China Company endured extremely cold weather and strong altitude sickness, and traveled all over southwest China, collecting environmental data on the use of plateaus and lakes, capturing special mission requirements, and providing effective support for the future use of AG600 aircraft in the plateau. A few months later, together with a team of designers, they traveled to Liangshan Prefecture, Sichuan Province. The forest area is high altitude, surrounded by mountains, rugged and changeable, aviation fire extinguishing is the fastest and most effective means to fight fires here, they and the research team, carefully visited various areas of the forest area in a few days, and handed over an AG600 aircraft for the plateau fire fighting capacity demand research report.

Over the course of a year, the team traveled more than 180 days away. They handed over stacks of market research results to the designers of the R&D team. This is the first step in positive design driven by demand.
On the other hand, combined with the major scientific and technological achievements made by the technical verification aircraft in independent innovation, on the basis of inheriting the overall layout form of the "upper single wing, T-tail, front three-point landing gear, large aspect ratio single-step hull, landing gear system and power system", the potential of the existing aircraft platform is fully tapped, and the optimization design of the overall, aerodynamic, hydrodynamic, structural strength, various systems and five characteristics is carried out.
The team made improvements and optimized the design.
In the early stage of aircraft improvement and optimization design, "whether to change", "how to change", and "big or small" are the problems that plague the team. The contradiction between the big and small problems exposed by the various tests of the technical verification machine and the initial design indicators and the design goal of "usable, easy to use, and early use" has gradually found a balance point.
In round after round of demonstration, the improvement plan of the pressurized cabin has been increased from the addition of a pressurized cabin in the nose of the aircraft, the addition of a pressurized cabin in front of the 32 frames to the pressurized cabin of the whole aircraft, and the team overcame the impact of zero industry-related experience, expert doubts, financial pressure, and the impact of the epidemic, and finally effectively ensured the design indicators. In this way, the R&D team overcame many challenges one by one, such as the new airfoil, the key technology of the water-by-water fire extinguishing mission control system, the new fly-by-wire flight control system and the integrated avionics system.
The tremendous pressure did not break the team, but ignited their fighting spirit. Within one year after the improvement and optimization, the R&D team withstood great pressure, integrated resources, collaborated, united, took responsibility, riveted full strength, and continued to overcome key technical problems such as multi-engine propeller aircraft wing stall separation control, excessive water resistance peak, and large load coefficient hull design through theoretical design and test verification.
AG600M (1003 aircraft)** off the shelves.
In 2020, the development of the whole line worked day and night, so that the new AG600M aircraft completed the preliminary design and detailed design work in only 8 months, AG600M (1003 aircraft) completed the production of parts and the delivery of large components in 8 months, completed the ** and commissioning in 6 months, completed the ground test before the first flight in 5 months to achieve the first flight, and immediately completed the first flight on the water and the 12-ton water test in the full state after the first flight. The R&D team continues to interpret the "Kunlong Spirit" with practical actions, and refreshes the history of the development cycle of large-scale new domestic aircraft again and again.
After the improvement and optimization, the maximum take-off weight of the AG600M aircraft has been increased to 60 tons, the maximum water has reached 12 tons, the cruising altitude has been increased to 7600 meters, the pressurized cabin is set, and the fly-by-wire flight control and integrated avionics system are adopted. The improved and optimized AG600M aircraft safety, mission execution ability, comfort and economy have been significantly improved and enhanced, with a wider range of applications and higher mission efficiency, realizing a real "full state" and "new configuration".
This is the fruitful achievement of the R&D team to overcome difficulties and overcome difficulties, and it is one step closer to the goal of AG600 aircraft playing an important role in the construction of emergency rescue system and natural disaster prevention and control system as soon as possible.
