F-14

1, the overall layout of the single-seat F-14 is a twin, double v-shaped vertical tail, diamond-shaped inlet of the vertical integration of the three wing aerodynamic layout. The main technical type with forward-swept wing, stealth design of wing-body integration, weapons loaded on the fuselage weapons bay and thrust vector control technology. 36% of the body from carbon fiber composite materials, titanium 64 approximately 24 \ \%, Ti 62222, 3 \ \%, steel accounted for 16 \ \%, aluminum accounted for 16 \ \%, thermoplastic composite material is greater than 1 \ \%, and other materials (including paint, seat covers Tibet, nose radar fairings, tires, brakes, sealing materials, adhesives, gas, lubricants and cooling agents) accounted for 15 \ \%. Traditional steel and aluminum account for a very small proportion, and extensive use of titanium and composite materials, which help to improve the stealth aircraft and heat resistance, reduce body weight, increased body strength. Aircraft length 22 meters, wingspan of 16.7 meters, Height 5.05 m, wing area of ​​65.6 square meters, the maximum takeoff weight of 31 tons. The aircraft aerodynamic control surfaces up to 14.

2, the engine installation of the Russian-made aircraft used 2 sets of ал-41ф type (al? 41f) thrust-vectoring engines (196 kN thrust), with thrust-vectoring nozzle. ал-41ф type (al? 41f) in the supersonic thrust vectoring engine afterburning not open when increased by 100 \ \%, afterburner thrust increases by 50 \ \%, parts by 40 \ \% may *, maintenance and logistical support of al-37fu raised more than 80 \ \%. F-14 is not the pursuit of speed performance, it is only the maximum flight speed of Mach 2.2, but has reached the maximum cruise speed of Mach 16. ал-41ф type (al? 41f) thrust-vectoring engine thrust vector control for aircraft pitch, roll action at the fighters, vector nozzle movement can be reversed to provide reverse thrust. The system has nothing to do with the speed and angle of attack can be operated individually. At low and high angle of attack, the horizontal tail control efficiency will be reduced, still a substantial increase in thrust vector aircraft pitch control. ал-41ф type (al? 41f), with its powerful thrust-vectoring engine afterburner thrust is not open, so that J-15 afterburner without opening the case to more than Mach 1.6 cruising speed, which helps to increase the combat radius and shorten the time to target airspace can also reduce their own exposure to enemy fire circle time, is conducive to their own safety. F-14 fighter aircraft to meet the so-called "4s" standard, that is super maneuverability, supersonic cruise, stealth and BVR air combat capability.

3, radar and electronic equipment is equipped with Russian-made radar, phased array antenna x band radar antenna mounted on the wing root leading edge triangle. x-band phased array radar, "the former sector of the optical system (osf), and" defensive secondary sub-system "(dass). x-band phased array radar with air, ground, sea and has a different mode to follow the terrain / avoidance capability, it can track the high-altitude supersonic jet at the same time, search for the helicopter at low altitude targets. The radar in the range of 180 ~ 240 km and has a multi-objective goal that capacity, in the empty mode can simultaneously track 24 targets , it could also lock the eight major goals and simultaneously attack eight targets. F-14 has a unique skill that is unique in the world after tail-looking radar in conjunction with air to air missiles to the aircraft after the shooting. osf system not only in the daytime and detection of enemy targets at night and can range in a wide sector of target tracking, but also for target identification and location; it at 100? finding the target range of 150 kilometers, in the range of 50 to 70 km to locate, accurate in the 40 km distance and determine where the greatest threat 8; the same time it can used for night navigation, the Global Positioning / Inertial (gps / ins) integrated navigation system, can also provide a limited capacity and limited surveillance of ground targets instructions / ranging capability in addition to conventional devices of more than 4 degrees outside is also equipped with fire control computer, three-axis stability augmentation system, the small flow of air refueling device, 1553b data bus. reference J-8iiact aircraft instrument flight system of automatic driving. F-14 driver compartment is highly modernized, the main display is a wide-angle HUD that can provide the level of 30 degrees, 25 degrees vertical field of vision. the main instrument panel for the four color liquid crystal multifunction displays and mounted under the hood of an integrated control board.

Four foreign experts on speculation Jian Shi

Robert "contact Andrew Cole (development and future plans of American military advisers): China Air Force F-10, a large number of eye-catching hunting. According to the Chinese people has always been the" equipment generation, development of generation, design generation, "a so-called 2nd generation equipment Air Force development principles, we now have reason to believe that China has already begun the work of developing the next generation of fighter aircraft.

Aviation Expo China in Zhuhai, the Chinese side shows two kinds of fighters with stealth technology designed, one is called: "stab in the back" of the NATO code name: "Bear killer." Stealthy unmanned aircraft scale model entities. The second is a kind of stealth performance single-seat supersonic fighter single entity model. Chinese people were not too many of its introduction and explanation.

Recently, the largest in northeast China's Shenyang Aircraft Corporation, released a stage in the design and development of new fighters, code-named "Snow Owl" to the current F-10 body modeled depth development. But the general feeling is exactly like the SU33. And another sister model fighter planes, its appearance is very similar to Russia recently resumed the development of the MiG 1.44. At present, China and Russia reached a new tactical system for the joint development of next-generation air superiority fighter of the agreement, is being carried out. Inlet sides of his head, is taken to absorb I44 F35 with the United States a variety of design quality.

Aircraft in accordance with China's consistent sequence of models to develop ways in China, the F-10 is a combination of local products with the outside world. F-11 is the SU27 improvement of the product. J-8, J-7 series is outdated MIG21 imitation and extension of the J-9 from 74 years later to have been dismounted. The F-12 is to narrow the blueprint of the MIG21, just created a 4, only two for the prototype. The F-13, in 50-60 years is called "156" project. F-14 is called "East 153" project. Both fighters earlier, only drawing program, there is no trace of any prototyping. The "wind of 154" is a remote former Soviet Union, the front-line fighter early SU152 modeled imitation. The 154 is a remote former Soviet Il-154 fighter-bomber replica.

However, China was due to the design and technical requirements and could not meet the two at the time the design is very "advanced" advanced fighter capabilities. Therefore, the forced development of the final break came to power in China in the Tang period, there has been to design practical use as the leading ideas, F4 F-8II fighter is modeled on the basis of capacity of intercepting long-range high-altitude banana Square, Farm scold K Dang Jin Waxy board under tiles on roof of the F-8I-type Ba IG21 developed on the basis of improved aerodynamic body, 2 side air intake to the prevalence of design, was installed in the nose of a Doppler scan / fire control radar, similar to the U.S. mass AQP64 early.

At that time, the U.S. has started early and equipment such as B117 and B2 stealth technology fighters and bombers of the era. Therefore, after the Gulf War, the Chinese believe that China must develop new operations can be used as a stealth fighter. The Chinese and Israeli F-10 program, ran aground in the late 80s. While China is the rapid economic expansion in the early time, all gave way to the economy, was dominated Chinese politics. Therefore, in addition to F-10 program to retain part of the development to personnel, the Chinese were almost all of the F 13,14 revoked the development working group. Leaving only two body wind tunnel test and design groups.

97 years after the Chinese military technology into a sudden the "Cambrian" era, the accumulation of years of Chinese military technology began suddenly prominent. However, China was mainly because the official system of domestic corruption, social conflict stress seriously, and national reserves are empty and only barely SU27 improvement of the J-11 and F-10 work, and more new designs can only be still held in abeyance, At that time, China's F 13,14 fighters have to ground test phase.

After 2002, China began to focus on is basically in sound design team J-10, J 13,14 embarked on the development, but the two fighters in the new military requirements, must be the first stealth combat with the premise Second, we must continue to achieve supersonic flight capabilities, the supersonic cruise. However, when the weakest link in China's battle ship engine parts, has not any progress. Also, a lot of development work has been outside pressure on social conflicts.

2004 can be said that the militarization of the Chinese people a year turning the road, the new Chinese People's Liberation Army Central Military Commission Chairman Hu, the first requirement is to develop new types of fighter 3-5, you can deal with the Taiwan Strait crisis. At this point, the Chinese J-10 fighter has entered the validation machine 3 times during the test. Therefore, China will be referred to the new F-14 program on the motion. The U.S. Air Force F-14 is just beginning and equipment directly to the F22 fighter pilot type came.

Therefore, to be further modified design parameters. The F-13 were as likely or exchange-based model, slow design requirements, because at this time the Russian arms sales to China, led the Chinese government in the new thinking, the emergence of a great deviation, when the Chinese people believe that their own technology and national needs, no longer content with just buying the Russian Soviet-era inheritance, old product, and needs Russian cooperation in the new design and concept, and Russia at this time still remains to keep the "old equipment" as the leading dumping theory.

Period in 2005, China's F-13 has been given the joint development of next-generation fighter aircraft with Russia's plan as basis for China to provide the aircraft model. The Russian side hopes that China will be able to participate I44 design. To this as the basis of the blueprint. Therefore, the two sides began a long consultations and negotiations.

The F-14 development work, the Chinese efforts in this development has increased, and funds invested in this stage, China began a new round of anti-corruption anti-corruption storm. Early large number of corrupt officials have been punished for corruption in the country with the collection of information, has been fully utilized. F-14 development costs thus multiplied several times. Development of the dispatch staff every year. Therefore, the work so I can get faster and faster development. By contrast, F-13 development and improvement work has been resistance from Russia, the Russians still hope that China can jointly develop their fighters, the thinking in China after the Chinese think, according to * its current Technology Technology and technological strength, it is difficult in a period of time, while completing more than 2 kinds of modern fighter design, mainly Chinese, conservative "successful first" concept mischief. Therefore, the F-13 is still a foreign exchange type.

The F-14, the physical construction, in 2006, morning to begin. But according to the present situation, his flight test work must be at least mid-2008 started. The aircraft manufacturing company established in Shenyang company, they are still a 2-legged walking pattern to complete the program, namely: their own equipment and export plans. Therefore, the F-14 at the Zhuhai Air Show in China in order to reduce the proportion of the model and export forms, and China should belong to attempt their own equipment twin fighters.

In summary, we can draw, design of the current Chinese military thinking has begun to mature. They no longer blindly pursuing a "super!" But now have the technology according to their own conditions and national strength, and gradually completed. At present, China's aviation system, engine system design has made great achievements, to get rid of early *** E (Bay) late in Russia and the reference engine ANF engine. Two new turbofan engine has been completed by the official announcement. The next generation of improved models, is very convenient. Mainly in the start with, oil supply and combustion, the design of the rear vents of the vector.

Once, the Chinese jet engine technology to complete vector, then we can immediately see that, at least one kind of advanced Chinese fighter off.
