Concerned about China's future development of aircraft carriers at the same time, Western military experts have begun to focus on China's next generation of fighter jets.

Canada, "Han Defense Review," in March 2006 an article published in number, said China's next generation fighter has been exposed, which means that China's fourth-generation fighter project has begun to project research.

The article said that the network has recently appeared on the so-called Chinese Air Force J-14 (F -14) fourth-generation fighter image, of course, just from their appearance can be known as "strange" character. "Han and the Defense Review," has been reported by the Zhuhai Air Show in recent years, aircraft on display in the video can be seen that the first group, China has launched a fourth-generation stealth fighter development program. At least two different aerodynamic shape of the model being tested. Sources have also stressed that in Shenyang is currently engaged in a preliminary study of next-generation heavy fighter. Han and analysis, development seems to remain stuck in the wind tunnel experimental stage, whether it has produced a full-size model to be seen. In Chengdu, since the J-10A's development has been completed, based on the design of a new stealth fighter or a modified single-shot J-10 program of course, exist.

"Han and the Defense Review," that, in order to develop the next generation of fighter aircraft, China's two major problems still need to tackle key problems, first of all is the engine, followed by the radar.

First, from the engine, the United States the use of the F/A-22 two WP-F119-PW100 turbofan engine, a single post-combustion afterburner thrust of 156 kN / 15907kgf (1kN = 101.97kgf). The F-22A's air weighs 14.062 tons, good thrust to weight ratio makes F-22 high-altitude supersonic cruise speed of up to M1.82.

Look at Russia, to tie in the fifth-generation (West, 4th generation) stealth fighter plane, Russia has begun development of a new generation of engines. The next stage of transformation is to AL-31F afterburning thrust of up to 14.5 thousand kilograms, and the installation of a new digital automatic flight control system, the same time the system integrated into the aircraft control system. More next-generation AL-41F turbofan engine, a single thrust of 196 kN (19986kgf), high-temperature gas turbine inlet temperature than the Chinese Air Force to use AL-31F higher than 250 degrees, up to 1700 degrees.

For China, the development of next-generation supersonic cruising ability with high-power engine remains a major technical obstacles. Concrete expression to date, is the third generation of the engine has not yet used in the actual combat phase. Therefore, to immediately put WS-10A modified to 15,000 kg afterburner thrust level, it takes time, the key is the performance must be stable and reliable. For this reason, J-10A is still using the AL-31FN, 2005 年 11 月开始 delivery of a new batch of AL-31FN, while the WS-10A may also need a number of years of service.

Therefore, Han and assumptions, China's fourth-generation fighter engine needed, especially in the pilot phase, it may still need to cooperate with Russia, even after the import of AL-31FN improved.

Second, from the radar system perspective, the next generation of stealth fighter's radar systems into an active phased array radar era. F/A-22A use AN/APG77 multi-function radar. AN/APG77 of 1 square meter multi-function radar, known as aerial targets with a search distance of 200 km or more, in the latest in a simulated aerial combat, an F-22A shot down five F-15C and the latter found little F-22A's位置.

Russia Phazotron Design Bureau designed ZHUK active airborne phased array radar in a number of technology has matured. ZHUK right hemisphere before the fighter target distance as the search has reached 200 km, scan angle of plus or minus 70 degrees. You can track-while-scan 30 aerial targets, and attacks on them 8.

"Han and the Defense Review," that they understand the situation is that China's fighter airborne active phased array radar development work has just project. But also in the passive airborne phased array radar in R & D is also seeking cooperation with Russia. However, the Russian side believes that China's airborne radar scanning the field of mechanical progress has been very fast, close to the world advanced level. Thus, for the fourth-generation fighters of the active phased array radar research and development, has accumulated rich experience in the basis, if supported by the Russian technical support, and then 10-year period, there will be significant gains.

Finally from the weapons systems, China's open two kinds of stealth fighter model is also designed with the U.S. F-22 fighter jets to bomb a similar built-in compartment, therefore, the design of next-generation fighter, the United States and Russia in the built-in weapons, increase stealth the idea of performance is the same. Currently open PL-12, SD-10 air to air missiles, the stability of the wings, tail diameter ratio of the early AIM-120A even greater, therefore, for the PL-12 bombs placed in a built cabin, but also as the AIM - 120C, as re-stabilizing wing design, so that miniaturization.

Satellite-induced bomb would be essential for the next generation of fighter-ground attack weapons. Russia has also been developed for this bomb GLONASS-induced, J-14 using the satellite-induced bomb in two directions, first choose a Russian GLONASS systems, which Russia is willing to provide military standards of GLONASS to China will depend on the two sides political relations and China's battle. The other path is China's self-developed Proactive Beidou satellite positioning system, is currently being planned, said that there is 9, 11 layout of the program. That China is likely to develop "Dipper positioning weapons."

"Han and the Defense Review," The conclusion is that "people are concerned about J-14 fighter jets have already started, but the road still seemed remote." vinit mundhra (talk) 18:32, 17 November 2009 (UTC)[reply]
