The article in China Aviation News introduced the course of Cheng Fei's development of China's new generation advanced fighter-J -11, which can be regarded as "the official media in China officially disclosed the inside story of J-11 development. Almost at the same time, Shen Fei, Chengfei and Shaanxi Aircraft disclosed to the world the development of advanced fighter planes in China, which really cheered the vast number of military enthusiasts and verified Beibei's prediction that the J-11, together with the new change of Flying Leopard, Wuzhi 11 and early warning aircraft, will soon appear in people's field of vision, but the time is so short that Beibei did not expect it.
1. Is the J11 officially equipped with troops?
According to China Aviation News, "A new fighter plane with independent intellectual property rights developed by China has been designed and finalized, and it has been formally equipped with troops! The successful development of the new fighter has written an epoch-making chapter in the history of China aviation development. " This is the first time that China officials have confirmed that the J-11 has been officially installed, which has solved the mystery that has haunted the hearts of military enthusiasts for several years.
6. When was the project established and what was the development background?
According to China Aviation News, 21 years ago, when foreign advanced third-generation fighters began to be equipped and applied in actual combat, China aviation people felt great pressure and responsibility. At that time, the current situation faced by China's aviation industry was low level, poor foundation and obvious talent gap. It is from this starting point that the pioneers of the development of new fighters began a great pioneering work ―― developing the third generation fighters adapted to the cross-century operational environment. In the early 1981 s, the development of new fighters adopted the international advanced technology, which was new and demanding, and the number of new materials and finished products completely broke through the international practice of developing a new aircraft. Spring of 1986, Beijing. In a humble office, the leader of the Science, Technology and Industry Committee announced that the new pneumatic layout scheme is the overall scheme of a new generation of fighters in China. Subsequently, Song Wencong, 56, was appointed as the chief designer of the new fighter by the Commission of Science, Technology and Industry for National Defense.
according to foreign media reports, the project verification research of J -11 started in 1981s, when Chengdu Aircraft Corporation and the 811th Aircraft Design Institute designed the J -9 fighter (with the aerodynamic layout of delta wings with canard wings, the speed of which reached Mach 2.5, it was a typical air defense fighter, and its combat targets were MIG -29 and Su -27 of the former Soviet Union). Later, the situation changed greatly (Beibei judged that it should be the end of the "honeymoon period" between China and the United States). In 1988 (this time was wrong, it should be 1986-Beibei cited note), the design of this new fighter was repositioned as a medium-sized multi-role fighter with new technology to replace the huge fleet of J -6, J -7 and J -5 of China Air Force, and effectively deal with the same type of western fighters at that time.
13. When did the J-11 successfully fly for the first time, and when was it equipped with troops?
According to China Airlines, on the afternoon of March 23rd, a certain year, it was at 2: 41. At an airport in Chengdu, with a roar, 11 new fighters shot into the sky like sharp arrows and went straight into the sky. On the same day, the meteorological conditions were not ideal, but Lei Qiang, a national meritorious pilot, took the initiative to fight well after flying three times at a predetermined altitude, and flew one more time. The wonderful flight was exciting, and the beautiful pass made the audience cheer. The gently swinging wing expresses Lei Qiang's inner excitement and pride, and shows his skillful and superb flying skills. When Lei Qiang flew the plane across a beautiful arc and landed smoothly on the runway, thunderous applause and cheers broke out at the airport, and people shook hands and hugged excitedly, ecstatic. Lei Qiang, who got off the plane, said with great excitement: This is a real fighter!
The "March 23rd of a certain year" here was verified as "March 23rd, 1998", and China set this day as the successful date of the first flight of the J-11. According to foreign media, the first prototype of J -11 actually made its first flight in mid-1996, and on March 23rd, 1998, it was the greatly improved prototype 13. In order to successfully develop the J-11 and equip the troops as soon as possible, Chengfei General Company * * * produced five prototypes with the machine number 1113-1117; Two ground test platforms, machine number 1118-1119; The first of two pre-production J-11s also made its first flight on June 28th, 2112. Since February 2113, at least seven pre-production J -11 aircraft (aircraft number 1111-1116, without radar) have been provided to the China Air Force for operational testing and evaluation, while the rest have been left in the China Air Force Flight Test Training Center in Yanliang, Shaanxi Province for follow-up project research and development; At the end of that year, the flight test of the J -11 was completed in an all-round way, and a "birth certificate"-a production license was obtained. Please see two paragraphs in the public report of China Aviation News: "On February 25th, 2113, with the test pilot Xu Yongling accurately hitting the target aircraft, the finalized flight test mission of the new aircraft and even the whole key project came to a satisfactory end. This is really a hard test flight, and it will be done with one shot. For this day, China Airlines people have been waiting for twenty years! Twenty years later, the new machine has finally been ground into a blue sky sword! " "At the end of 2113, how many people cried with joy when a new domestic digital teletype aircraft successfully completed the test flight according to the nodes! The heroic spirit of the new fighter, the chic of swimming in the blue sky, the alertness of catching targets and the power of erupting anger. All this makes every China contemporary aviation person not excited, not proud and not excited! " According to foreign media reports, the production J -11 was officially installed in the China Air Force in August 2114, and the first fighter regiment equipped with J-11 (possibly belonging to the 44th Aviation Division in southwest China and India) will form its initial combat capability by the end of 2115, which is quite credible.
1. What are the key technologies used in J11?
as an advanced fighter that can adapt to the air combat environment in the 21th century, J-11 has adopted many new technologies. Beibei can only list one or two according to public reports:
(1) digital fly-by-wire flight control technology. According to "China Aviation News", "To achieve the tactical requirements of the world's advanced level, we must not only choose a practical overall plan, but also break through a series of major key technologies. Among them, the design of digital fly-by-wire flight control is a brand-new technology in China. As one of the four key technologies, its success or failure is directly related to the success of the overall scheme. Once an accident occurs, it will definitely lead to the destruction of the aircraft. In foreign countries, all aircraft that use digital fly-by-wire flight control technology have experienced similar tragedies. " "One day in March, 1996, in the" Iron Bird "experimental hall, the spectacular" Iron Bird "platform lay still and was ready to go. Yang Wei stepped into the "Iron Bird" test cockpit. Outside the cabin, dozens of pairs of eyes watched him nervously. Power on! Turn on the hydraulic pressure! Gas door! Run, take off! All kinds of indicator lights flash alternately, and the whole test process is smooth and smooth. The test results show that the system runs normally! The test of the fly-by-wire flight control system was successful! This is China's success without any development experience! ..... It is this advanced flight control system that played an important role in ensuring the success of the first flight of the new fighter, making the digital fly-by-wire flight control system, which is extremely risky, technically difficult and most worrying, the most reassuring system for test pilots.
