Prior to this, most of the domestic fighters of J-10, J-11, J-15, etc., used AL31FN as their aero engines. They are the fourth-generation turbofan engines with afterburners introduced by Russia. They are well-known among domestic military fans. Gao, there are many "unreasonable" military fans, who call the Russian-made AL31FN aero engine "three uncles."
"Salute" (Rulika Design Bureau) was the first to equip it with a dedicated aero engine for the Soviet Air Force's twin-engine heavy fighter Su-27. Since then, it has also been used on Su-30, Su-33 and Su-35 fighters.
AL31FN thrust 13-13.8 tons, has the characteristics of small size, large thrust, high stability, and easy maintenance. It is generally believed that the service life before the first maintenance can reach 1000 hours, and the total service life is 10 years.
As early as July 2011, Rosneft National Defense Products Export Corporation signed an agreement with China to provide China with 123 AL-31FN aircraft engines before 2013. The total contract value is more than 500 million U.S. dollars and the average unit price is more than 4 million. U.S. dollars; previously, 54 units, 100 units and 122 units were introduced respectively, a total of 349 AL31FN aircraft engines (about 600 units, 340 units for the complete machine, 250 units for the F-11A and the first batch of F-11B).
During the test of the AL31FN aeroengine, Chinese aviation scientists found that it is comparable to the Western F119-PW in terms of fan ventilation flow, inlet temperature before the turbine, and turbine cooling airflow control, including high-altitude acceleration performance and improved thrust rating. The -100 engine has a considerable technical gap, and the conclusion is that the overall performance of the AL-31FN is not ideal, and all aspects need to be developed and improved.
After entering the new era, the Air Force will realize a strategic transformation and rely solely on the introduction of a large number of "Salute" AL-31FN aero engines. This is not only not conducive to the improvement of the national aero engine development level, but also not conducive to the export of domestically developed fighter jets. In fact, The J-10 fighter has been unable to achieve zero breakthrough in export sales. The Russian-made AL-31FN aero engine is used on the aircraft, which restricts its export and has a considerable relationship.
Chinese aviation scientists and technicians have concentrated their efforts on domestically-made Taihang series aero engines, including turbofan-10A, which is an inevitable requirement for the Air Force to achieve strategic transformation and development. They are unwilling to be subject to the constraints of other countries in the field of aeroengines and can be equipped with domestically-made fighter jets. The aero engine is bound to be born.
The J-16 is a domestically-made main fighter, with very strong overall combat performance. When ground strikes are the mainstay, it can mount up to 12 tons of ammunition. It can be called an aerial "bomb truck". The choice of domestically produced aero engines has gradually matured and its performance The excellent turbofan-10A aero engine has become an inevitable choice.
The core of the turbofan WS-10A is the product of the Russian AL-31F engine and the American CFM56 engine mapping. Its overall performance is close to F110-GE-129IPE (the improved performance of F110), and its service life has been increased to 1500 hours. The 1000 hours of the Russian-made AL-31FN engine has increased by 50%. Although it is still inferior to the average service life of Western aero engines, it is a great technological advancement for the Chinese Air Force aeroengine.
The J-16 is a non-stealth third-generation semi-fighter, equipped with the fourth-generation stealth fighter’s active active electronic scanning phased array radar, and a novel photoelectric detection system. Its airborne avionics and stealth There is no big difference between fighter jets. To some extent, they have the ability to carry foreign stealth fighters.
The J-16, which can identify and attack multiple targets at the same time, has long-range over-the-horizon air combat capabilities and powerful ground (sea) strike capabilities. Currently, the three aviation brigades after the military reform have been equipped with approximately 120 equipment. Right and left, the air combat capability is second only to the J-20 fighter, and the ground (sea) strike capability is above the J-20.
The J-16, in terms of its overall combat capability, has far surpassed the Su-30MKK multi-purpose heavy fighter that was introduced from Russia in the early 21st century. It can plug various types of air combat and ground weapons in active service. After the software is upgraded, it will be enough. Launching the latest type of YJ-12 or YJ-18 heavy-duty ultra-long-range air-launched anti-ship missiles, with the ability to fight aircraft carriers at sea.
