Suddenly appeared! The domestically produced coaxial rigid rotor high-speed helicopter, we want all the things that the United States has! China's aviation technology is "exploding".
The coaxial rigid rotor high-speed helicopter has perfectly solved the stubborn diseases and safety hazards of the previous Russian Kamov coaxial twin-rotor helicopters, which were fatal defects.
The coaxial rigid rotor has good high-speed performance, allowing the helicopter to break through the 400 km/h speed barrier, with a maximum flight speed of 450-480 km/h.
This speed exceeds China's Fuxing high-speed rail. The "Fuxing" high-speed train set independently designed and manufactured in China can reach a maximum speed of 400 km/h, and the actual operating speed is 350 km/h.
However, the disadvantage of the coaxial rigid rotor system is the extremely high noise during high-speed flight, which is several times higher than that of conventional helicopters, making it difficult to carry out covert operations in complex enemy areas, and noise reduction design is needed.
