四代重歼采用10项先进技术（The four generation of heavy fighters adopts 10 advanced technologies）

四代重歼采用10项先进技术（The four generation of heavy fighters adopts 10 advanced technologies） 四代重歼采用10项先进技术(The four generation of heavy fighters adopts 10 advanced technologies) The new generation of China heavy fighters with at least 10 of the world's most advanced technology With regard to the development of China's fourth generation advanced fighter 14, reliable information has been available for nearly 20 years. According to the latest research, the day of this fighter's debut is no longer out of reach. The main combat performance of America's fourth generation fighter F-22 and Chinese the real threat around there so 14 fighters of the tactical and technical requirements of the changing of the aircraft's avionics system and power system requirements are also gradually improve. In the face of Russian proposal provided by the Chinese Air Force leaders and military commanders were not satisfied, and China military under the current circumstances, do not want to put the secret weapon for any country to know or grasp, but do not want to be in charge of our trump card weapons procurement authority. Therefore, after the development of the new generation of main fighters in the United States F-22 and deployed around China, the development and testing of the fourth generation of new fighters in China has entered a rare fast lane. At present, our latest fighter 14 is being intensively tested. Reliable news has taken at least 10 of the most advanced technologies in our country and even in the world: One. Excellent invisibility. On the aerodynamic shape of the 14, users guess more, but most of us expected and almost F-22, but we still have many advantages in the integration, the United States and Russia, the twin vertical canard wing technology has its own characteristics. The machine in addition to the wing body fusion technology and the extensive use of composite materials such as stealth technology, docking site still the structure of the whole machine, used in stealth machine verification Jian test the success of the "sawtooth docking technology", which is no longer use the traditional straight docking mode, each large interface ("zigzag" flying glass cockpit interface, and the fuselage of aircraft landing gear hatch, large-scale structure of the junction, weapons hatch, nozzle baffle), which can greatly reduce the reflection of radar reflection beam intensity. The advantage of the front canard is that it can provide the aircraft with excellent super maneuverability, which is in our new fighter plane 10 has been proved, and I believe everyone should see it. As for the new fighter's twin tails, although we developed fighter has no actual use, but we introduce domestic technology f 11B fighter, is already a very mature technology, we have to do is to the original twin vertical tail J 11, improved double inclined vertical tail, the manufacturing company in the latest technology in China Shenyang fighter aircraft, what should not be difficult! Two. Advanced computer-controlled large thrust vectoring exhaust nozzle. Due to the strict stealth technology, so the 14 fighters used domestic large thrust vectoring engines in China and improved in an imported aircraft engine on the basis of the machine nozzle and the nozzle with round square vector, vector nozzle technology similar to Europe and Russia, according to the computer from the nozzle automatic flight control system command, automatic adjusting nozzle vector direction and nozzle diameter, so as to achieve the best effect of super maneuver flight. The jet engine is completely different from the -27 and 11 series of Su f extended body tail, but deep in the back part of the body, so that you can have easy space layout engine infrared suppression device, for aircraft infrared stealth into the best condition. Three. Wing integral fuel tank technology. The fourth generation combat aircraft with emphasis on stealth effect, therefore, must use the built-in weapons technology, built-in weapons technology will occupy the original aircraft fuel tank position, therefore, the fourth generation of new aircraft must adopt technology wing integral fuel tank. The so-called integral wing tank is a new type of modern fighter, in order to maintain its cruise and combat range, in the case of built-in weapons rack, Most of the fuel tanks are arranged in the wings of the aircraft (in this case, the aircraft has almost no wing load, so the weight of the original weapons can be converted into fuel oil). To master this technology should be proficient in computer automatic adjustment of dynamic balance wing wing fuel oil supply system, otherwise, to supply aircraft engine is not balanced, resulting in wing imbalance, is prone to major flight accident. Moreover, due to the relatively large wing area, the probability of being hit in wartime is relatively high, so the wing integral fuel tank to solve the problem of self-protection after the bullet, which involves the problem of fuel tank liner. Fortunately, this problem of our country has already solved this technology in our country's armored vehicle fuel tank, fuel tank, helicopter assault tank car was used, which can be effective flame retardant, can significantly reduce the leakage of oil tank was hit by a continuous, conducive to the protection of the safety of aircraft and pilots. Four. Built in air to air missile weapon and its launch management system. Because of the limited volume of the airframe, it is not easy for the fighter to build the weapon, especially the volume of the similar missile in our country is larger than that of the foreign ones, so it is more difficult to realize. But under the ingenious conception of our weapon experts, these problems have been solved, but our missile load may be relatively less. There is an important weapon control system, it is also a key, because the target in the fire control radar, the system will automatically select the desired bomb, bomb and timely to the selected power supply and input control parameters, then put the bomb into the launch window. Five. Technology of composite large structure parts. This is the third and fourth generation fighters have begun a large number of application technology, the technology can significantly reduce the aircraft body weight (so as to increase the payload of the aircraft and the fuel load) without reducing the flight structure strength, also is easy to realize the purpose of stealth aircraft. The United States and Japan have achieved the aircraft wing integral composite technology, and other smaller parts is a large number, and its use has exceeded half the weight of the aircraft. China has realized the composite vertical tail rudder, rudder, etc. a large non composite technology key pieces of the structure, the proportion of application of composite materials in military aircraft are more and more, we have reason to believe that the application of composite parts f 14 aircraft will have new improvement. Six. Ion plating metal reflective film technology in glass cabin. This technology is mainly to prevent aircraft pilots and equipment in the cockpit reflect electromagnetic waves, so as to be detected by the enemy. If driving this metal reflective film coated on the glass in the aircraft cabin, the aircraft cabin driving electromagnetic signal cannot be reflected to the plane wave emitted by the enemy, but can not enter the cockpit can reflect electromagnetic echo, thereby greatly reducing the probability of being found. In addition, all the joints of the cabin are treated specially, and the electromagnetic wave reflection ability is reduced to the minimum. Seven. High temperature stealth coating technology for engine inlet and engine intake fan. As the aircraft engine inlet and the turbine fan engine blade is a reflection of radar wave source is larger, and the former major department of radar detection of aircraft back to the source, therefore, the new aircraft stealth to also focus on solving this problem. In order to reduce the radar echo intensity, the inlet channel is often designed in a curved shape, and air inlet lip is arc, and the turbine fan blade because can not easily change the shape, therefore, the turbine blades are usually coated with a layer of different from the body of the special stealth coatings. Eight. Long range phased array multi-target fire control radar. China's fighter borne fire control radar technology has made great progress after drawing on the technology of France and russia. On this basis, the new phased array airborne radar developed by our country has been finalized. It is said that the prototype is first mounted on the 11B to carry out the experiment, and when the destroyer 14 formally finalized the service, it will be formally equipped with this type of radar. The radar has the capability of multi target processing, and the actual detection range reaches * * km, It can detect and control targets at the same time and attack the targets at the same time. But stealth aircraft because it needs to focus on hiding themselves, generally can not arbitrarily open their own airborne fire control radar, so as not to expose themselves too early. The United States F-22 fighters to enter the combat zone, generally rely on the ground detection and early warning satellite sky radar, air warning aircraft and the detected information, to realize information sharing by using real-time data chain. Our 14 fighters in service, is expected to rely mainly on ground-based radar to obtain the target information, the estimated future Chinese in addition to the development of airborne early warning aircraft, radar warning satellite will also be included in the development of military Chinese. Nine. Polymer surface wave absorbing composites technology. In recent years, the polymer absorbing microwave material technology in our country gradually reveals the mysterious veil. I believe that in our memory, all types of fighters in China are silvery appearance (aluminum skin color), if the distance is close enough, you can see the wide body gap and a lot of hot rivets. And these places are exactly where the radar wave reflection is most concentrated, the reason why our military aircraft is easy to detect and identify, from this. This is not only the problem of aircraft manufacturing technology, but also the long-term drawbacks of aircraft design in our country. Now, these things have changed greatly, from this we can see the f-10. In the 14, the tenon joint gap has been greatly reduced, the heat rivet traces almost invisible, in bridging and spraying developed our own polymer microwave absorbing materials, new fighter China's appearance is uniform and smooth, combined with the original stealth design, the stealth effect is almost incomparable. These stealth materials have been developed and improved from the first 1 to now, and now 2, 3 and 4 are coming out at the same time. Ten. Automatic flight control management evaluation system. China's active driving the aircraft, because the flight control system of our country are relatively backward (mainly by manpower control), the vast majority rely on individual pilots flying qualities to control, therefore, flight work is so hard and exhausting. Remember that a material has said, the United States and Europe aviation aerobatic team flying out difficult stunts, the distance between the aircraft fleet is automatically controlled by the automatic flight control system, and China's "women" aerobatic team to fly out of the same level, is to rely on their excellent quality and training to achieve the! Therefore, the long time flight work of foreign advanced fighter pilots is very easy, while our pilots have long flight time, the physical strength will consume a lot. Therefore, our country in the field of automatic control of flight, spare no effort to catch up at the end of last century, it initially reached the advanced level in the world. Some models have been developed successfully in China, has been officially equipped with the most advanced fighter, the J-10 fighters, such as 11, leopard and other models. In the F - 14 equipment is more advanced in computer models, can be scheduled flight tactical action, automatic completion of a variety of difficult training subjects, and greatly reduce the work intensity of pilots. The 14 advanced fourth generation combat aircraft, aviation industry of China in the new century about work, is also our country to catch up with the world advanced level as a representative fighter. The 14 fighter aircraft built in service, not only can greatly reduce the technology gap between China and advanced countries in flight, the reform and opening up economic results can also be effective protection of our country, and can fully meet the many countries purchased advanced level fighter needs! It is expected that the aircraft will soon become China's new "killer" after starting its small batch service in 2010. It will shoulder the important task of fighting against the newest fighter aircraft of the United States and its Asian allies!
