America Journal: China’s fourth generation fighters is not as powerful as F-22, but it can consume F-22

F 22 300x220 America Journal: Chinas fourth generation fighters is not as powerful as F 22, but it can consume F 22The United States, “Aviation Week” website November 24, 2009 published entitled “China’s commitment to a new type of advanced fighters,” the article, signed from the Washington, DC David A. Fulghum and from London, England Douglas Barrie. Articles pointed out, U.S. intelligence officials believe that China has received most of the U.S. stealth fighters how to build the necessary data, but the lack of integration of China’s aviation industry may be the key to a four-generation machine skills; The article also mentioned that the younger generation of Chinese aircraft performance, not necessarily comparable with the F-22, once mass production, the number of foreign experts, to be passed by “full consumption” tactics to suppress the U.S. military’s 187 F-22, eventually will be completely “consumed” the U.S. F -22 stealth fighter unit.

The article first said that Air Force officials and intelligence officials say China has the resources and technology to build a fourth-generation fighter aircraft. But China’s aviation industry may be a lack of key skills, this skill is to create an advanced fighter-jet maker with the West comparable to the performance fighter needs.

The article said, either in Beijing or the West’s defense sector, China still is not clear whether the technicians who really have the kind of engineering systems and capacities and capabilities of such systems is to achieve mass production of advanced weapons, aircraft and achieve the needed the performance of such advanced fighters to be similar to those aging B-2 stealth bombers and F-22 stealth fighter, or similar to the relatively new ability to some of the less stealthy F-35 “Lightning II” fighter. A U.S. Air Force officer, said: “(To build a new generation of fighter) you need to the appropriate shape, mechanical design, surface coating, aerodynamic performance and flight control systems integration together, although this is not magic, but there are a lot of skills on the inside. ”

The article mentioned the fact that there is no conclusion: The PLA Air Force would have to seek an optimum design of low detectability of the fighters, or in terms of performance, maintenance, carrying capacity and delivery schedule, the Air Force What are the requirements mentioned. US Office of Naval Intellig ence in 1997, China developed a new fighter called “J-XX”, this aircraft, or would seek a more “balanced” approach to achieve the stealth effect, and perhaps to focus on the front of the fan-shaped area radar reduction in cross-sectional area, or the use of appropriate coating to achieve stealth, rather than seeking full stealth design; the twin-engine, canard-delta wing concept had previously been recommended for the general design layout of new fighters.

“Aviation Week” website article goes on to say that China is unlikely that within 10 years to create a performance similar to the F-22 fighter aircraft platforms, although the recent news that China’s new fighter under development and will soon be to first flight. A U.S. intelligence official, the Chinese air force is also a senior analyst summed up the way the Chinese access to advanced technologies, he said: “In the legal, quasi-legal and illegal transfer of technology between, I believe that China has received most of the relevant How do we build stealth fighters and other aspects of architecture and materials, data, they also made full use of our open patent system, our public universities and research institutes, engineering, and we discuss the data in the academic … … “The article also mentioned that the growing the aging F-22 fighter jets and B-2 stealth bomber design is another factor, which gives China more than 20 years researchers time to catch up with these technologies. B-2 bomber, has also experienced its first service-life-extension program.

This U.S. intelligence official also said China from the United States, Japan, South Korea, Russia and the European Union all the way to obtain the necessary data, China’s R & D types of fighters and the only restriction being invested capital, and manufacturing process engineering and integration of integration the capacity of the various subsystems, these things Americans do best, and these skills truly reflect the group culture and the learning curve, not just readily available data, although similar to ISO 9000/9001/9002 systems and the standardization of software systems let “for” processing techniques has become much easier.

The article said that China’s F -10 fighter, performance similar to the US-made F-16, F -10 fighter plane engines, avionics systems, and aerodynamic performance is considered the best fighter on behalf of independent R & D efforts in China, this fighter in 2006 began a large-scale service. China spare parts for Boeing aircraft manufacturing and aviation materials and gain knowledge and skills development of China’s military aircraft have been helpful. The initial F -10 fighter R & D from Israel’s “lion” type fighter program benefits, but also by the Russian support.

The article also mentioned that China has also used from the Russian-made Su -27 “Flanker” fighter developed from the F-11B fighters, the F-11B as a platform for the introduction of Chinese self-developed avionics, fire control radar, weapons systems and power systems, and further repeated these subsystems for the F production appears to be-11B, may be intended for a specific J-XX project. F-11B fighter aircraft designed to be equipped with PL-12-type mid-range active radar-guided air to air missiles, rather than imported Russian-made R-77 (NATO called the AA-12 “Viper”). PL-12 air to air missiles, guided weapons development reflect China’s technology base has been fully upgrade, although the project was of great help in Russia.

U.S. intelligence officials said today, China’s real target is the face of an arms race in India, and in this process, the Chinese are winning. Although this competition has no direct impact to the U.S., but at least some of the Pentagon’s decision-makers believe that this will accelerate the pace of China’s strong military and war-making capacity, while the U.S. has been to focus on a limited response to the conflict of war and rebellion in military spending and technological development above. “In my view, we in the low-altitude low-speed MC-12 reconnaissance aircraft, MQ-1 / 9 unmanned aerial vehicles, C-27J transport aircraft and F-35 light fighter in billions of dollars in wasted costs,” that this intelligence Officials say so.

The United States, “Aviation Week” website article also quoted one pairs of F-22 fighter project has in-depth insight into the veteran fighter pilot as saying, (China) to build an advanced fighter aircraft, even though its performance can not be with the F-22 and F – 35 comparable, but if this aircraft has been substantial and sufficiently produced by complete consumption of tactics to suppress (the United States and) when the allied forces, then it will remain on the United States pose a serious threat to the stealth fighter unit. While an American aviation industry officials said, when those four-generation fighter with great quantity (advantage) trapped 187 U.S. F-22 was difficult, they will eventually be completely “consumed” the United States F-22 stealth fighter Force; if (China) them to the number of F-35 fighter planes to create an advanced, they do not have to be with the “Raptor” comparable to the performance.

The article also concluded that, for China, in 10 years leap forward in technology, creating a similar F-35 fighter is not impossible. And a U.S. Air Force senior officer said: “They (China) will be invested in something like that a lot of resources.”

U.S. experts say China may have obtained some of the F-22 and F-35 fighter planes technical

F-35 fighter jetsU.S. Global strategic networks on the 17th reported that the Chinese Air Force claimed that it will be within one year flight test performance, comparable to the U.S. military’s most advanced fighters of the new F-22 fighter planes, saying this new aircraft will be fitted out within a decade. In this regard, although the U.S. intelligence agencies believe China is still far unable to obtain this ability, but also that China may have obtained the construction of F-22 and F-35 fighter part of the performance of advanced technologies.

The article quoted U.S. intelligence experts as saying that China’s space technology, whether design or production capacity can not be independently developed F-22 or F-35 fighter levels, but China’s current self-designed two planes (J-10 and JF-17 ), it seems that China may have been capable of producing F-22 or F-35 fighter parts of the level of advanced technology.

The article said China’s development of an advanced fighter jet is one of the greatest difficulty in engine technology. 20 years China has been committed to the independent development of aircraft engines – any high-performance aircraft, a key component – of the production technology. Up to now, China has not received its most advanced fighter engines must produce all the production techniques and skills. For example, China is Russia’s RD93 engines (originally designed to provide the impetus for the MiG fighter -29) and an important customer, has purchased hundreds of which engine. At present, RD93 engine priced at approximately 2.5 million U.S. dollars.

Reported that China had developed a similar engine with the RD93 that WS-13, but Chinese sources said the engine will soon put into use. This engine in the development period, China received help from Russia, the latter providing the former with a key part of the engine to produce the required technology. Reported that China’s recent re-ordered an additional 100 units RD93 engines. The construction of high-performance military jet engines is not easy, the Chinese in this area have already experienced a number of difficult issues. This is not to say China can not get to build high-performance military jet engine technology, but access to this technology before they will inevitably need to Russian RD93 engines. According to Chinese official said that the reason for China to buy more units RD93 engines because they can not produce enough of the WS-13 engine.

Reported that the Chinese engineers have mastered the manufacture of Chinese version of Russian-made AL31F engine production technology, and research and development for the F -10 fighter and was put into operation two years ago is the Chinese version of the WS10A engine AL31F engines. However, the Chinese Air Force WS10A engine reliability and performance and not satisfied, from Russia ordered an additional 100 units AL31F engines coming off the production line as F -10 fighter’s heart. At the same time, Russia is also trying its rival with a new F-22 fighter planes to improve AL31 engine, but has encountered a number of serious problems. So, China can overnight beyond Russia?

F -10 fighter is China’s first independently developed an advanced fighter. The aircraft is to build planes that can compete with foreign made an attempt in modern fighter aircraft. F -10 fighter R & D work began more than 20 years ago, aims to develop a Russian-made MiG-with -27 or -29 and Su-US-made F-16 fighter jets comparable. However, up until 1998, when the prototype aircraft which began to conduct test flights. Until 2000 when the Chinese to solve the in-flight testing, we found some of the basic design flaw. To 2002, China built a nine prototype, but in subsequent flight tests also found hundreds of small problem.

Reported that the Chinese engineers, is this an excellent learning opportunity, but could not contend with the Russian-made fighter F -10 fighter Su -27/30 is also an indisputable fact. In fact, the F -10 fighter looks a bit like the US-made F-16 fighter jets, and the two planes is almost the same weight, is 19 tons. Different from Su -27, -10 F and F-16 fighter planes, like all single-engine.

Weighing 13 tons of the JF-17 fighter jets equipped with RD93 engines, is developed by US-made F-16 fighter planes low-cost alternative. Which aircraft jointly developed by China and Pakistan. Although the JF-17 fighters and early models of F-16 fighter capability rather, it is only equivalent to the effectiveness of the new F-16 fighter planes to 80%. Which fighters of the Russian Mig -33 aircraft aborted the project R & D base, equipped with electronic equipment manufacturers, mostly Western countries, while the Italian company is the main supplier.

JF-17 fighter jets capable of carrying weight of 3.6 tons of weapons systems, the use of radar-guided and heat guided missiles. Its maximum speed of about nearly 2,000 kilometers, a range of 1,300 km, service ceiling of 55,000 feet. So far, China still has not installed on its own whether it set out a decision FC-1/JF-17 fighter. Obviously, this is because China believes that the F -10 (autonomous R & D) and J -11 (built under license in Russia, the Chinese version of Su–27) fighters have been sufficient to meet their needs. However, with the JF-17 fighter similar to F -10 fighter’s performance and not achieved the desired results.

China L-15 advanced trainer aircraft and the F-22 has been on display together – Attracted international media attention

L 15 300x199 China L 15 advanced trainer aircraft and the F 22 has been on display together   Attracted international media attentionNovember 15, at the 11th Dubai International Airshow, a new generation of China’s own R & D L15 advanced trainer aircraft made an excellent flight performance, causing a strong reaction. This is the L15 following the 2008 Zhuhai air show to air show again in the form of public appearances, but also the first time in foreign countries L15 for flight performances, and became the only one of China’s aviation industry in-kind exhibition of aircraft.

14:48 local time, from two Chinese super test pilot Mr Yeung, ZOU Jian-guo driving L15 advanced trainer aircraft to accelerate the pace of take-off roll to the ground from the ground and began to show in a foreign-made models of higher education to performance.

First, going through a horizontal “8″ fly. Aircraft from the ground, direct access to up turns to adjust the position, and began the next horizontal “8″ flight to demonstrate their excellent vertical mobility. Suddenly, L15 height has risen sharply and the aircraft rose to peak altitude of about 900 meters, and then roll out a 180-degree inverted dive changed to accelerate the decline in aircraft dropped a beautiful arc and change to re-enter up gesture, the following will be in the opposite direction to complete the next horizontal “8″ moves the second half.

Subsequently, the aircraft straight and level flight at about 200 kmh-pass field, showing a good low-speed flight characteristics. Thereafter, L15 smooth completion of a full two weeks in a row roll-pass field flying, inverted pass field, rolling a 180-degree turn to inverted flight, vertical rise in motor as well as in reduced vertical height of 200 meters after the increase in flight demonstrations.

L15 advanced trainer aircraft circled low from time to time, sometimes suddenly straight, in the vertical flight, L15 as if the train has already left pierce straight into the sky, reaching an altitude of 900 meters, fully demonstrate its superior vertical mobility. Last L15 landing a small airline based flight show a perfect curtain call. The audience responded with warm applause to celebrate L15 advanced trainer wonderful success of the flight performance.

The flight performances also fully demonstrated the excellent L15 vertical mobility, horizontal mobility, high angle of attack characteristics and low-speed flight characteristics and so on, tens of thousands of spectators from around the world witnessed the L15 machine Excellence grace of higher education, and Dubai air show flight performances added touch of beautiful scenery.

L15 flight performances came in the United States F-16 aircraft, after performances, behind in Italy before the M346 advanced trainer aircraft, which is in this Air Show to compete directly with the L15 an advanced trainer aircraft. Since then, the world’s most advanced F-22 aircraft flight demonstrations. L15 is the mainstream media to become the current Dubai Airshow Air Show, one of the three stars, they are the U.S. F-22, Europe’s “Typhoon (Typhoon)” China’s L15.

L15 advanced trainer aircraft for the Air Industrial Hongdu independently developed a new generation of advanced jet trainer, a successful maiden flight in March 2006, 2008 and 2009, respectively, to achieve 03 and 05 prototype first flight. Participated in the Dubai Air Show, the L15 advanced trainer for advanced trainer (AJT) state test prototype, equipped with an AI-222K-25 non-afterburning turbofan engine. After hundreds of sorties were flown to adjust flight tests, AJT state theory of the flight envelope has reached the boundary, the system works normal and stable, and has been transferred to flight test phase of the design identified. At present, the aircraft industry Hongdu are actively engaged in fighting L15 induction training (LIFT) the state trial work, the status of aircraft will be equipped with AI-222K-25F afterburning turbofan engines, to further enhance the L15 motor characteristics.

L15 advanced trainer aircraft in order to ensure the smooth progress of the Dubai air show performances, as early as the beginning of the Industrial Air division will be organized in defense aircraft industry Hongdu other units to actively start the preparatory work of exhibitors, from the air show profiles, transitions route to ground maintenance, technical support, pilot training and other aspects to develop a detailed program. In October, L15 off a new round of flight height, according to the Dubai air show air show program, completed in China in more than 20 flight drills, constantly optimize the flight parameters during the flight to ensure that each action is done precisely in place to so that flight profile can be both a very strong view of the safety requirements to meet the airshow scene. In addition, the transitions in Dubai for the mission requirements of the transition function test flight, the aircraft successfully laid a solid foundation for participating.

It is learned, L15 flight test stage in the research and actively participated in major exhibitions at home and abroad. 2008 Zhuhai Airshow, L15 for the first time in an open air show in the form of a new appearance, and flying 13 sorties a row, becoming the Zhuhai Airshow, one of the most dazzling star. Subsequently in this year’s model and flight simulator in the form of participation in the Paris Air Show, Moscow, exhibitions and so on, causing a strong reaction.
