J-11 fighter
The J-11 is the Chinese version of the Su-27 (in 1997 Russia signed an agreement with China, which allowed China to produce Su-27 fighters. This fighter, of China's own production, was designated J-11. The J-11A is the Su-27SK produced in China, and its main performance indicators are basically the same as the Su-27SK. The J-11B is a new type of fighter developed by China on the basis of the Su-27SK J-11A after completely understanding the Su-27SK. This airframe is almost a copy of the Su-27 in terms of style, but all kinds of functions are improved by using Chinese technology. Compared with the Su-27SK J-11A, the main equipment of the J-11B has been replaced with a domestic model, which is a reborn transformation. Improvements made by the J-11B include: the use of composite materials (mainly carbon fiber), the weight of the aircraft is reduced by more than 700 kg, and the life of the aircraft is increased by 10,000 hours;The air intakes of the engine were redesigned to reduce the radar cross-section, coupled with the use of composite materials, and the application of radar absorbing materials;The avionics equipment has been replaced with domestic standard equipment, which can be mixed with domestic precision guidance such as R-77 and Thunderbolt-12 medium-range air-to-air missiles, and has strong ground attack capabilitiesThe cockpit features four new head-up displays;Equipped with WS-10 turbofan engines;With a new domestic fire control radar, it is estimated that it can simultaneously detect 20 targets and attack 6 of them at the same time, while the Su-27SK can only attack 2 targets at the same time;A new ultraviolet missile proximity warning system was installed, with two sensors installed on the tail section on both sides;153 items of randomly developed domestic latest electronic equipment. It is claimed that the J-11B has a fuel carrying factor of 37% and a maximum range (one refueling in the air) of 5200 km. In addition, the forward-looking infrared detection system on the J-11B has a self-detection repair system project. The J-11BS is a two-seat fighter developed on the basis of the J-11B. The aircraft was originally considered a two-seat trainer version of the J-11B, but later it was generally accepted that the aircraft was a multi-role fighter similar to the F-15E.
J-16 fighter
The J-16 fighter is a third-generation half-generation two-seat twin-engine multi-role heavy fighter developed on the basis of China's domestically produced J-11BS.
The J-16 follows the large side strip and conventional layout that has been used by the "Flanker" family, and has superior aerodynamic performance. However, compared with the J-11B, which focuses on air superiority missions, in order to perform multi-purpose missions, the J-16 has made certain improvements in the fuselage structure, such as strengthening the fuselage structure in order to increase the bomb carrying capacity, and strengthening the structure around the wing outboard hardpoints for heavy-duty external hardpoints. At the same time, in order to improve the heavy-duty take-off and landing capability, the J-16 replaced the single-wheel main landing gear of the original J-11B with a reinforced two-wheel main landing gear that is more suitable for rough take-off and landing. The purpose of structural reinforcement is to reload, and it is expected that compared with the J-11B, the J-16 fighter with the PL-15 and PL-10E on the parade may increase the maximum take-off weight by at least 3 tons, and its maximum load will exceed 12 tons. The large load, one means an increase in the bomb load, and the second means a significant increase in the fuel load, and the J-16 is expected to have a range of about 4,000 kilometers, which is significantly ahead of the new "Flying Leopard" fighter-bomber. In addition, the J-16 is also equipped with a fuel receiving pipe, which can further extend its range and combat radius through air refueling.
In addition, in terms of appearance, the details of the tip of the vertical tail of the J-16 are different from those of the Su-30M K K, the former retains the conventional cut tip design, while the latter has a horizontal and flat tip. In fact, from the perspective of aerodynamic theory, the cutting of the vertical tail is conducive to preventing the stalling of the vertical tail wingtip, improving the aerodynamic efficiency of the vertical tail, and improving its heading stability and maneuverability at large angles of attack. From this point of view, the purpose of using the J-16 with a vertical tail and cutting tips is to retain the air combat maneuverability of the J-11B as much as possible;The Su-30MKK, on the other hand, is more focused on strengthening the combat capability of the opposite side, and no longer pays special attention to retaining the tradition of maneuverability of the "Flanker" series. It can be seen that although the J-16 and the Su-30MKK are both developed following similar improvement ideas, they are different in design positioning, the former can be called a multi-role fighter, while the latter is a "fighter-bomber". The J-16 fighter is an improved version of the J-11B in China, and the J-11B uses the turbofan-10A "Taihang" engine in China. At the beginning of the early batch of J-16 fighters, the turbofan-10A "Taihang" engine was directly applied, but after the installation of the J-11B domestic heavy twin-engine fighter, the turbofan-10A was continuously exposed and found various problems in use (such as broken first-stage blades, damage to the engine casing and other equipment), and at the same time, it was successively improved in subsequent production and research and development, and "high reliability" was launched Compared with the turbofan-10A, the improved turbofan-10B has a thrust that meets the design standards, but the most important thing is that its reliability and actual service life have been greatly improved, and the actual installed service time has increased from tens to hundreds of hours in the early days to hundreds of hours, and the engine first turnover period and life indicators have been significantly improved. From "Taihang" to turbofan-10b, it marks that "Taihang" has completed a major leap from being able to be installed and used to being "usable". At present, the J-16 has been replaced with a turbofan-10B engine with greater thrust, better envelope, better service and maintenance, and its performance has been further improved.
The J-11 is mainly used for air interception and close air combat missions, and is one of the main fighters of the Chinese Air Force. In air superiority combat, the J-11 can perform tasks such as intercepting enemy aircraft, protecting important areas, and performing air patrols. 2.J-16 fighter: The J-16 is an important multi-role fighter in the Chinese Air Force with strong ground attack capabilities. It can carry a wide range of missiles and precision guidance** for missions such as ground target strikes, blocking enemy ships, and long-range combat. Summary: The J-11 and J-16 are important representatives of the two generations of fighters in the Chinese Air Force, each playing an important role in different aspects. The J-11 is mainly used for air interception and close air combat, while the J-16 is a multi-role fighter with stronger ground attack capabilities and integrated combat capabilities
