    Latest J-20 installed with WS-10B turbofan engine is a milestone

    The thrust, reliability and digital controll level of the "Taihang" WS-10B engine totally surpasses the Russian AL-31F series engine. The most critical thrust indicators: WS-10A/B thrust 13.5 tons better than 13 tons of the AL-31F thrust . And the maintenance of convenience and automation level have improved.

    This will ensure that the comprehensive performance will not decline when using domestic-made "Taihang" engines. The most important thing is that Chinese J-20's engine supply will never be controlled by the other country after using the WS-10B engines. The core aircraft technology and production capacity are firmly in Chinese hands. At the same time, the upgrading "Taihang" WS-10B engine can also accumulate flight test data for the four generations jet fighters and also can provide valuable information for further development of the WS-10 series turbofan engines.

    BEIJING, Sept. 28 (Xinhua) -- China's latest J-20 stealth fighter has been officially commissioned into military service, according to Wu Qian, spokesperson for the Ministry of National Defense on Thursday.

    The flight tests are being conducted as scheduled, Wu said at a press conference.

    The J-20 is China's fourth-generation medium and long-range fighter jet. It made its maiden flight in 2011 and was first shown to the public at the 11th Airshow China in Zhuhai, Guangdong Province, in November last year.

    True, and add to that the fact - 50% of faculty and graduate researchers in universities abroad are chinese.

    Chief Designer of J-20 turbo fan engine, Gan Xiaohua, Academician of China Engineering Academy, said :

    China's military use aviation engine is generation or even more behind the most advanced level in the world .

    China is changing this pattern, in 2016, China launched the implementation of aviation engine and gas turbine projects, direct investment of not less than RMB 100 billion, the total investment will reach RMB 300 billion yuan(USD 45.11 billion). Aviation engines R & D and manufacturing have become a national strategy.

    In the past, as not engough money and needed urgently by the defence industry, Chinese aviation engines were produced with reverse engineering and imitation for military use. Now it is not the same. doing basic research and innovation is very important. Based on the strong basic research and a variety of technological accumulation, the development of a new engine does not need to spend 10 years like before, and it will only take 2-3 years to complete. The good example is the new WS-10B based on WS-10A turbo fan engine.

    Chinese Rhenium nickel alloy single crystal blades used for turbo fan engines


    One private enterprises, called "Refining the stone in colors"

    In 2010, in Luonan County, Shaanxi Province, Huanglong, the company discovered rhenium in the molybdenum mine exploration. Reserves reached 176 tons, accounting for about 7% of global reserves, has aroused great concern at home and abroad.

    In order to find more rhenium,this private company's subordinate, the Chengdu Aerospace Super Alloy Technology Co., Ltd. and Hunan Institute of Nonferrous Metals , cooperate together for more than a year to overcome the technical problems and achieve the rhenium purification.

    However, sitting on such a scarce resource, they have found: this rare metal in the country is almost no market -since the domestic rhenium development and utilization is almost a blank!

    In desperation, they turned their attention to the international market and hope to use the model of resources exchanging for technology, and seek the cooperation with foreign companies such as alloy manufacturing.



    As the technological blockade of the other countries and the strategic importance of the aviation engine, it needs for a breakthrough. As a result, the company decided to produce its own single-crystal blades.

    The aviation industry investment is huge, period is long and return is slow, and single crystal blade is the most difficult parts in the manufacturing of turbo fan engines since the process is long, the pass rate is the lowest and the foreign blockade and monopoly is the most serious.



    With the help of government's "thousands talents plan" , the company invited a dozen foreign top experts - they have worked in several major well-known aircraft engine company, has many years experience in aircraft engine parts R & D, manufacturing, installation testing and quality control.

    But the equipment is lack of. After several twists and turns, they finally found a British single crystal furnace suppliers to solve the problem.

    So, by the end of 2013, in Chengdu, Shuangliu suburbs of the original barren land, the Chinese domestic single crystal blades start to sprout.

    July 22, 2015, Chengdu Aerospace first batch of products released, qualified rate was stunning.

    In 2016, the international authority of the third party testing organizations issued a test report shows that Chengdu Aerospace Super Alloy Technology Co., Ltd. for inspection of single crystal blades in the high temperature tensile properties, high temperature durability and other aspects of the test results are in line with European standards.

    Chengdu Aerospace has thus become the first domestic enterprise of single crystal blade mass production level .

    So far, single crystal blades into production time is just a year.

    Single crystal blades as the most core components in the turbo fan engine, the successful mass production is very important to the Chinese aviation industry.
