Last night, the aviation giants in Europe and America must have worked overtime all night! Because China Aero Engine Corporation directly threw out a king bomb! "This technological breakthrough is simply breaking the physical ceiling!" In the early morning of March 2, my country Aero Engine Corporation announced a major breakthrough in the CJ2000 turbofan engine on its official blog. The thrust has reached 35 tons. This engine has completed 3,000 hours of endurance testing, which is equivalent to a fully loaded C929 passenger plane flying in the eye of a typhoon for 125 days. The fuel efficiency of this engine is 15% higher than that of the GEnx engine on the Boeing 787, which means that for the same range, we can add 15% less fuel than them, and even sell 15% more tickets. The world's largest single-crystal turbine blade produced in the workshop in Jiangsu has also reduced its scrap rate to 7.8%, and its temperature resistance has reached 1,700°C. The carbon ceramic brake disc of Xi'an Institute of Aeronautical Materials is also very good. The 3D printed combustion chamber has reduced its weight by 12% and its life has increased by 1 to 2 times. Behind this inspiring blog post by AECC are the unremitting efforts and hard work of countless engineers. It is because of them that our country with thousands of years of history has risen in the field of modern aviation. It is also because of them that we see the strength of our country.
The CJ2000 engine is a strong "Chinese heart" independently developed by AECC. It is equipped with a dual-channel long-range wide-body aircraft. The circular air intake is arranged in a circle of neat fan blades with a diameter of more than 3 meters. The take-off thrust exceeds 35,000 kgf. It has the product technical characteristics of low fuel consumption, low emissions, low noise, high reliability, long service life and low maintenance cost. Many indicators are better than similar products in service abroad. It is a "national heavy weapon" leading in innovation. In December 2020, the "CJ-2000AX verification machine bottom component telemetry system hardware configuration" was launched for bidding, which means that my country's CJ-2000 engine may enter the verification machine test stage. The CJ-2000 engine is a new type of high bypass ratio turbofan engine developed by my country for the new generation wide-body passenger aircraft CR-929, with a designed maximum thrust of 35 tons, which is the same thrust level as the Trent 1000, Trent XWB and GEnx engines used by Boeing 787 and Airbus A350.
