On December 24, 2017 (November 7, 2017 in the lunar calendar), the first domestic large amphibious aircraft "Kunlong" AG600 successfully made its maiden flight. On December 24, 2017, a large blue and white aircraft started and taxied on the runway, the nose was raised, and it flew straight into the sky. The first domestic large amphibious aircraft "Kunlong" AG600 (hereinafter referred to as "AG600") independently developed by China Aviation Industry successfully made its maiden flight at Zhuhai Jinwan Airport on the 24th. "This is a ship that can fly, and it is also an aircraft that can swim." The AG600, the world's largest amphibious aircraft under development, will today usher in its first research and development test flight at Zhuhai Jinwan Airport. In accordance with the design idea of "amphibious, one aircraft, multiple types, and series development", the AG600 meets the requirements of forest fire suppression and water rescue, while taking into account the possibility and flexibility of modification into marine environmental monitoring and protection. As one of our country's "three large aircraft", the large amphibious aircraft AG600 carries the mission of the country and the nation. It is the largest amphibious aircraft under development in the world today. It is another major achievement made by our country in the development of large aircraft. It fills the development gap of our country in the field of large amphibious aircraft and adds a strong "heavyweight player" to our country's large aircraft family. More than 95% of the finished products on board the AG600 aircraft are domestic products. The AG600 earlier carried out ground taxi tests in Zhuhai. What can the AG600 aircraft do? Shangtian forest fire extinguishing single drop 12 tons of water large fire extinguishing/water rescue amphibious aircraft AG600 is to meet the urgent needs of forest fire extinguishing and water rescue in our country. The first large-scale special-purpose civil aircraft developed is a major aviation equipment urgently needed for the construction of the national emergency rescue system. It has many characteristics such as amphibious and land use, large loading capacity, long range, moderate ceiling, wide speed range, and good ultra-low altitude flight performance. It is especially suitable for fire monitoring and forest fire suppression, maritime disaster search and rescue, marine rights and interests maintenance, marine environmental monitoring and protection, etc. In addition, it can also be used in marine monitoring, customs anti-smuggling, environmental and resource monitoring, air transportation, air tourism/sightseeing, and private business, etc., and has a very wide application prospect. The AG600 aircraft has many advantages such as rapid dispatch, fast arrival at the fire extinguishing area, large hourly water injection, high fire extinguishing efficiency, and wide coverage. It can quickly reach the fire location and extinguish the fire source as soon as possible. It is a very ideal fire extinguishing tool. After receiving the forest fire extinguishing instruction, the AG600 can fill the water tank at the land airport or glide to the waters near the fire source area to collect water and then fly to the sky above the fire area. According to the unified command of the fire extinguishing command system, depending on the size of the fire, or directly return water to extinguish the fire, or multiple machines can go back and forth to extinguish the fire. The maximum water load of the AG600 is 12 tons, and it can draw 12 tons of water at a time within 20 seconds. The single water injection area can reach more than 4,000 square meters. It can drop 12 tons of water at a single time, or it can be dropped in batches. It can also open a safe passage for trapped people and other fire extinguishers and fire extinguishing machinery to enter and exit the fire area. Going to sea: Rescuing people on the water can save 50 people at a time. In addition to being a "fire extinguishing expert", the AG600 is also a "rescue master" in the The golden time for sea rescue is 12 hours. Once the people who fall into the water in the sea accident are soaked in the sea water below 20 ° C, the life rescue time will be greatly shortened. However, the water rescue system and rescue facilities in our country are relatively backward, and they are far from adapting to the needs of water rescue work in the new era. For far-sea rescue, if the rescue is carried out by boat, it will take a very long time; the helicopter is very efficient in performing tasks, but they are "difficult to use" when the task radius distance exceeds 500 kilometers. Correspondingly, the AG600 has a fast speed, a maximum cruising speed of 500 km/h, a maximum voyage time of 12 hours; a maximum voyage of 4500 km. AG600 aircraft can carry out surface rescue operations under complex meteorological conditions of 2 meters high waves. Water emergency rescue can rescue 50 people in distress at a time, providing a guarantee for water rescue work in medium and long sea distances. AG600 aircraft has the advantage of being fast compared with ships in sea rescue, and the speed of this type of aircraft is more than ten times that of rescue ships. The maximum rescue radius of AG600 can reach 1600km, which can cover most of our country's sea areas and exclusive economic zones, especially the main sea channel where our country is prone to maritime disasters. After receiving the rescue instruction, the AG600 aircraft immediately carries the necessary rescue equipment and flies to the designated waters, visually and using the airborne search and detection equipment, conducts a hovering search, determines the position and coordinates of the ship and personnel in distress, and reports the local waters and the situation of the people in distress in a timely manner; when the weather and water conditions permit, the aircraft directly lands on the water, hits the water for rescue, and uses the airborne mobile lifeboats and other life-saving equipment to approach the people in distress, directly rescue the people in distress on the plane, and carry out necessary emergency treatment. If the surface wind and waves are too large and exceed the ability of the aircraft to take off and land on the water surface, life-saving equipment, medicine, food and water will be delivered to the victims at low or ultra-low altitudes to increase the chances of rescue of the people in distress and buy time for other rescue measures. The design and manufacture of AG600 fills the gap of large amphibious aircraft in our country and lays a solid foundation for the construction of emergency rescue system in our country. The overall technical level and performance of the aircraft AG600 flying in the middle of the sea have reached the advanced level of the current international similar aircraft. It has complete independent intellectual property rights and meets the requirements of China's civil aviation airworthiness regulations. The AG600 aircraft adopts a single-hull, single-wing cantilever and front three-point retractable landing gear layout; four domestic turboprop-6 engines are optional; the length is 37 meters, the wingspan is 38.8 meters, and the height is 12.1 meters. The external dimensions of the fuselage are comparable to those of the Boeing 737; the maximum take-off weight is 53.5 tons, the maximum cruising speed is 500 kilometers/hour, and the maximum flight time is 12 hours; the maximum flight range is 4,500 kilometers; it has the ability to perform a number of special tasks such as forest fire suppression and water rescue. After modification as needed, it can meet the multi-task needs of marine environment monitoring and protection, resource exploration, etc., especially to provide the fastest and most effective support and safety guarantee for the safety of navigation on the "Maritime Silk Road". It can take off and land on land and water, and perform multiple water-throwing and fire-fighting operations between water sources and fire sites In addition to taking off and landing on land, the AG600 can also take off and land freely in the water, "This is a ship that can fly, and it is also an aircraft that can swim." Huang Lingcai, the chief designer of the AG600, once said that the design and manufacture of the AG600 aircraft will greatly promote the development process of large amphibious aircraft, thus promoting the leap-forward development of the national emergency rescue aviation equipment system, filling the development gap of large amphibious aircraft in China, forming an amphibious aircraft design and development technology system with independent property rights, and comprehensively improving the design and manufacturing capabilities of surface aircraft (including seaplanes, amphibious aircraft, ground-effect aircraft, etc.) in our country.
