"the kun can turn into feathers and hang down from the sky, and can blow up the wind with ninety thousand blows; the dragon can shake up its scales across the sea, and hit the water with three thousand blows."
this is the legend of "kunlong" passed down from generation to generation. thousands of years later, it was transformed from imagination into an important weapon of the country.
the "kunlong" ag600 is a large amphibious aircraft independently developed by my country. this "behemoth", which is about the same size as a boeing 737, is full of innovations, and its research and development process continues to challenge people's imagination.
how does this plane fly from drawings to the blue sky? xinhua interview launches the "chief engineer of a great power" series of interviews, exclusively interviewing huang lingcai, the chief designer of the large amphibious aircraft "kunlong" ag600, telling everyone the story of his "two-way journey" with this large aircraft.

it's not that easy to take off from the water
the upper body is an airplane and the lower body is a ship. the "kunlong" ag600 itself is a contradictory body. huang ling, who has rich experience in aircraft design, encountered difficulties when he just started designing.
amphibious aircraft must take into account both hydrodynamic and aerodynamic characteristics, and must also consider issues such as resistance to wind and waves and resistance to seawater corrosion. regardless of the overall design layout or process and material requirements, seaplanes are much more difficult to develop than land-based aircraft.
the layout of aerodynamics, hydrodynamics and landing gear are the three "stumbling blocks" in front of huang lingcai. in particular, how to stabilize, fly and land on a special runway like the water is the development of the "kunlong" ag600. the technical difficulties of
"to design an aircraft that can 'swim', we must integrate many contradictions and find the best balance point." in the face of many difficulties, huang lingcai led the team to repeatedly verify and improve, and finally broke through on the "track" of amphibious aircraft. a road
huang lingcai couldn't hide his excitement when he saw the photos of the "kunlong" ag600 test flight at the zhanghe reservoir. he recalled it and said emotionally, "the ag600 is not only the world's largest seaplane with the largest takeoff weight under development, but also the most advanced system configuration and performance." airplane."

how strong is the rescue capability of the "kunlong" ag600?
the "kunlong" ag600 has the function of performing multiple special tasks such as emergency rescue, forest firefighting, and ocean patrol, and will become the "all-rounder" of my country's air rescue.
"after receiving the mission, it can fly to the sea area 1,000 kilometers away in 2 hours." huang lingcai introduced that the flying speed of the "kunlong" ag600 is more than 10 times that of the rescue ship. in addition to searching at low altitude on the water surface, it can also fly within 2 meters. rescue operations carried out under complex meteorological conditions with high waves can rescue 50 people in distress at one time
huang lingcai said that the advent of the "kunlong" ag600 has provided my country with an effective means to carry out cosco maritime rescue and ocean navigation safety patrols, and is of great significance to promoting the construction of my country's emergency rescue aviation equipment system and boosting the construction of a maritime power.
in terms of forest fire extinguishing, the "kunlong" ag600 is even more of a "sharp weapon". the "kunlong" ag600 can pour water back and forth multiple times between the water source and the fire scene to extinguish fires. it can draw 12 tons of water in 20 seconds and can fight fires with a single pouring of water. the effective fire extinguishing area of more than 4,000 square meters is at least twice that of similar foreign aircraft.
regarding the issue of fire extinguishing and water extraction, huang lingcai also said that "some external guarantees will be needed in future application scenarios." however, judging from the current radius of the aircraft's mission, water sources that meet the take-off and landing conditions can be found within a one-hour flight of 400 kilometers. land

aim at a new goal and set off
from project establishment to research and development, manufacturing, final assembly, and soaring into the blue sky, huang lingcai has personally experienced and witnessed every growth of "kunlong". according to the plan, the aircraft will complete the airworthiness certification within this year.
huang lingcai said, "after the aircraft is certified, we will also expand various mission capabilities according to user needs, so that 'kunlong' will form a series of products." looking back on the past, huang lingcai was filled with emotion: "this this aircraft is the expectation of generations of aviation people and reflects our country’s technological level and industrial strength. all efforts and efforts are worth it.”
however, what huang lingcai is most proud of is that the "kunlong" ag600 uses a domestic engine "with our chinese heart". he expects that with the breakthrough of core technology, domestic aircraft will lead the world.
as the chief designer of the "kunlong" ag600, huang lingcai believes that the aircraft completely exceeded expectations but did not give it full marks because they wanted higher wave resistance. now, huang lingcai is leading the team to research related technologies.
