The newspaper went to Zhuhai Special Rapporteur Zhang Jiajun reporter Liu Yang China's self-designed and developed large-scale fire-fighting/water rescue amphibious aircraft AG600 “Nanlong†successfully completed its first flight on land on the 24th in Zhuhai (pictured). At this point, the Chinese large plane "Three Musketeers" has all been flying. As the world's largest amphibious aircraft, AG600's follow-up test and future application scenarios have received great attention. The chief designer of the AG600 project stated that this “aircraft that can swim†can achieve cruising across the entire South China Sea. China’s military expert Fu’s Outpost told the “Global Times†reporter that in the future this platform will have a very broad military-civilian integration prospect. One day he will not be surprised to see the anti-submarine patrol aircraft modified by the AG600 and the amphibious early-warning aircraft serving aircraft carriers. Can achieve full-sea cruise of the South China Sea On the 24th of the Zhuhai Airport in Zhuhai, Guangdong, more than 3,000 people gathered in a large blue-and-white aircraft. The AG600 “Begosaur†large-scale amphibious aircraft was undergoing intense first flight preparations, starting, taxiing, and aircraft. Heading high, the plane took off smoothly at 9:39 and landed smoothly after 64 minutes, returning to the rostrum through the imposing watergate. This is another milestone in the development of China’s aviation industry after the success of the first flight of Jiyun-20 “Zhenpeng†and the C919 large passenger aircraft. Huang Lingcai, deputy chief engineer of the aeronautical industry and chief engineer of the AG600 project, described the AG600 as such: it is not only a flying ship, but also an aircraft that can swim. The aircraft adopts cantilevered upper single wing, the first three retractable landing gear, single-hull amphibious aircraft layout, optional 4 domestic turboprop six engines, the maximum take-off weight of 53.5 tons, can both take off and land on the land It can also take off and land on the water. It can fire the water between the water source and the fire site several times. The forest fire extinguishing and special fire extinguishing have high efficiency. It can drown 12 tons once within 20 seconds and the maximum refueling amount is about 370. Tons, the single-fire water-saving area can reach 4,000 square meters; AG600's aircraft cruising speed can reach 460 km/h, which is more than 10 times of salvage vessels, the maximum voyage is more than 4,000 kilometers, and it can rescue 50 people in distress at one time or The airborne materials loaded with the corresponding weight can be quickly responded and arrived quickly, with good land and water take-off and landing and low-velocity low-speed characteristics. The rescue operations can be carried out under complex meteorological conditions, and the anti-wave capability of taking off and landing is not less than 2 meters. Taking off from Sanya can reach any point in the entire South China Sea and achieve full sea cruising in the South China Sea. The first flight of the AG600 was also widely reported by foreign media. However, many articles link it with the Chinese military. The British "Guardian" said on the 24th that China's new amphibious aircraft has further expanded rapidly modernizing military forces. This year, China’s first domestic aircraft carrier launched into the water and complemented the Liaoning ship. The US CNBC website commented that China is also accelerating the research and development of cutting-edge military equipment while China is increasingly strong in disputed areas such as the South China Sea. The first flight of the Chinese AG600 is the latest example of China’s military modernization. Flight test is the key to the key Due to the special nature of the amphibious aircraft, it has to make two first flights. It may be more difficult for the water test to fly and the verification course is more complicated. At the test flight site, Global Times reporters did not hear the schedule of the follow-up on-board test flights. As for the difficulty of the on-water test, the Chinese Air Force expert Fu Shouzhe expressed to the Global Times reporter on the 24th. First, the resistance of water and air is not the same. When the amphibious aircraft takes off, the resistance will change drastically during the critical period. As a result, the aerodynamic characteristics and fluid characteristics of the aircraft are greatly changed. To overcome these difficulties, it is not an easy task to fly. Secondly, the aircraft put down the landing gear in the water and it was a difficult problem to control the direction when the water was sliding. Therefore, a new control method, the water rudder, is required. The working status of this special device is an important content to be verified when it is on the water. Also, the requirements for amphibious aircraft pilots are not the same as those for shore-based test pilots. They also need to have the qualifications of landing and landing at the same time. An AG600 test pilot previously interviewed by a Global Times reporter flew over 2,000 hours on models such as the Hyun-Hyun-5 developed before China. According to the test pilot, for test flight AG600, they specifically went to Canada for a period of three months of training. In his opinion, the most difficult challenge in the future flight test of AG600 is the storm surge resistance. According to him, AG600 will fly on the water after the first flight on land. The AG600’s first flight on the water will be selected for a quieter inland lake. Experts: Great military potential According to the “Global Times†reporter, according to the design concepts of “Amphibious, Amphibious, Multi-Type, and Series Developmentâ€, in addition to the main functions of water rescue and forest extinguishing, AG600 can also be modified according to the needs of the mission and is widely used in marine environmental monitoring. , marine resources exploration, island reef transportation and other uses. Fu Senti posted that China's large aircraft Three Musketeers have the potential for military-military integration. Yun-20 may follow the exchange of engines to achieve military conversion. C919 and AG600 can also achieve “military participation.†The US Boeing 737 series can be converted to military use. Early warning aircraft and anti-submarine patrol aircraft. A platform such as the AG600 will first fly in accordance with the civil airworthiness standards. After obtaining civil airworthiness, the possibility of developing a platform as a special model will not be ruled out in the future. First, as the world’s largest amphibious aircraft, the AG600 can be fully converted into an anti-submarine patrol aircraft. A large volume inside the aircraft can be loaded with many devices. Patrol, reconnaissance, anti-submarine and anti-ship weapons can also be mounted. Followed by water rescue, this is also a dual-use military-civilian function. In this respect, it is even possible to change the military and the civilian population directly. In particular, far-reaching island reef rescue has been put into urgent relief. At present, China’s sea and air forces are increasingly and frequently trained in the remote sea. It is necessary to consider in advance what happens in the training process and what equipment to use for rescue. This amphibious aircraft is a Very good option. There is the island reef transportation and supplies. This is also a military-civilian integration project. It can either transport civilian goods or transport military supplies. Fu Sentinel also believes that AG600 can be completely replaced by amphibious early-warning aircraft. Chinese aircraft carriers can currently only be equipped with ship-based warning helicopters, which greatly limits the overall combat capability of aircraft carriers. The range of amphibious early-warning aircraft is much longer than that of helicopters and even fixed-wing aircraft. Although it can't get on an aircraft carrier, it can completely land on the aircraft carrier, and then supplies oil and water supplies near the aircraft carrier, and then cooperate with the aircraft carrier to perform its tasks. â–²
