Fruits of strengthening of science and technology of China, the US and Europe are dumbfounded _ laugh look at old cow
Fruits of strengthening of science and technology of China, the Help Desk Tracking SoftwareUS and Europe are dumbfounded author: Marine Corps major Deng Xiaoping once said: "in the past, today or in the future, China must develop its own high-tech, high-tech in the world has a place in the field". This sentence has been inspiring technology in China.����Excellent Chinese, pregnant with the Chinese wisdom and wit, when mankind since the beginning of a new 21st century, keeping pace with the Chinese people in the field of high technology has finally caught up with the West, realize the aspiration of Deng. October 15, 2003, researched, and the first manned spacecraft "Shenzhou", fifth launch, the Chinese nation on the climbing World Technology Summit journey completed a great feat, is a new milestone in the history of China's space.����Major scientific and technological activities in this world to solemnly declared the world, China has become the United States, after the Soviet Union the world's third independent manned space State.����China "Tianhe first," super computer systems, to peak speed 4700 trillion times, and continues speed 2566 trillion times each seconds floating-point operations of superior performance ranked world first; China first Taiwan itself design, and independent integrated development of "Dragon," deep-sea manned diving device in world Shang with type of manned diving device in the has maximum design Xia dive depth--7000 m, this means with the diving device can in accounted for world marine area 99.8% of broad waters using, representative with deep-sea high-tech area of most frontier; Chang second, satellite smooth launched and full full established task, description has China analysis months engineering first stage smooth into finished and to second stage development,, and so on, these high-tech area of positions, China scientists a received a of conquer, China in technology Shang quickly closer and United States of distance, over has European. As a world power, to safeguard State sovereignty and territorial integrity of China, absolutely necessary to strengthen their own national defense building.����Implementation of "Science", focusing on winning the future of modern technology, especially under conditions of high-tech war, this is the 21st century, China's national defense strategy. "Science and technology" by scientific and technological innovation is the core of accelerating the pace of development of new weapons and equipment, promoting the development of weaponry, military weaponry by semi-mechanical, mechanical moving toward automation and informatization.����"Science and technology" aim high technology applied to weaponry, military combat capability, and take the road of troops with Chinese characteristics, realization of our armed forces from the number to the quality and efficiency, in terms of manpower-intensive to a fundamental change in technology-intensive. Is ASAT tests-free, anti ballistic missile test, the establishment of Beidou navigation system, anti-ship ballistic missile development, refitting "waliang" aircraft carrier, also successful maiden flight is a fifth-generation stealth fighter, space planes successful first flight, all of this shows that China's science and technology and military strength.����United States what China can and will have, this is the cattle in the field of science and technology in China. Some time ago United States test-fired the electromagnetic railgun, United States us ass jerk a jerk, high profile even claimed that electromagnetic railgun will be the future masters of war. Everyone knows China military study on early success, but I just don't want to quiet, fear of overwhelming-bashing ' China threat theory. It has been revealed: this kind of precision-guided weapon launched Hypersonic projectiles, within a few minutes rather than hours of the hundreds of kilometers of combat objectives. In search of foreign intelligence information at his disposal, it is understood that the Chinese military in re destroyer warship will include tracks for the future of artillery systems is as follows: a launch weight of projectile (including propellers and Chamber pieces) 20 kg; flying weight of 15 kg; the initial speed of 2. 5-kilometer/s; the initial kinetic energy of 63 megajoule; muzzle energy 150 megajoule, barrel length 12 m; launch speed 6~12/min; 15~30 megajoule system power demand; the projectile carried 2,560; maximum range 360-kilometer; in the objectives of the energy of 17 trillion Coke.����In combat, 15 kilograms of kinetic energy (not chemical) of anti projectile to Mach 8 times emission into the atmosphere, attack any target in the range up to 360-kilometer, no more than 3 minutes! so don't how long China high-tech cutting edge weapons make United States stunned will continue to occur, these leading-edge areas constitute a comprehensive stwrongful death attorneys floridarength of China's rapid promotion, China has the reason more confident.

PLA building satellite and radar network against us aircraft carriers _ heaven
Categories: military sources: a world made new medium-range ballistic missiles.����Chinese military counter-carrier simulation map.����United States recently published an article in the Washington Times said that invest heavily in China over the past 20 years, the PLA is modernizing. Recent fifth-generation Stealth Fighter fighter-the people's Liberation Army flight test 20 and anti-ship ballistic missiles with initial operational capability, on the United States and its allies have had a significant threat.����According to United States Pacific Command Admiral luobote��weiladehaijun, already have Chinese anti-ship ballistic missile threat to aircraft carriers.����The author of China's military modernization, lichade��feisheer also said that the fifth-generation Stealth Fighter fighter-20 is "truly profound threat." Article stated that Chinese anti-ship ballistic missile target from a moving aircraft carriers is not easy, but China has been in a positive way. China has initially developed a network of satellite and radar components, and the largest in the Western Pacific submarine fleet, and a lot of "fishing vessel" as an auxiliary in order to provide accurate location information.����In the future, maritime patrol aircraft and unmanned aerial vehicle will further enhance the positioning capabilities of these systems. Admiral Willard said the United States have not yet found any so far to anti-ship ballistic missile attack mobile targets in the test. But the Chinese are apparently making the necessary deployment, against intervention and blockade strategy to achieve them. It is unfortunate, United States on China's anti-ship ballistic missile and no clear answers.����If the people's Liberation Army succeeded in installing multiple, independent guidance in the anti-ship ballistic missile warheads, then the situation is even worse. Chinese anti-ship ballistic missile, a solution is equippHelp Desk Tracking Softwareed with the most SM-2 and SM-3 of new missiles, ABM and using new dual mode anti-ship misswrongful death attorneys floridailes. United States such warheads can be sold to Japan, and Korea and other Asian allies.����This will no doubt boost military deterrence. United States should also be a priority to upgrade F-22 "Raptor" fighter plans, so that F-22 can better than Russia, and China's fifth generation fighter aircraft.����In addition, you must also accelerate the implementation of directed-energy weaapplication business card creditpons such as laser, railgun plans. In addition, the United States unequivocally said to China, and United States think the PLA anti-ship ballistic missile deployment is "unfriendly". If the Chinese anti-ship ballistic missile used against the United States aircraft carrier, the United States would consider such attacks as attacks on United States home, and a strong response.
[Reprint] understanding J20 so shocking conclusion _ Zhou Zhongmin
Original address: understanding J20 so shocking conclusion author: vestigial Eagwrongful death attorneys floridale awareness J20 so shocking conclusion as the fighter-20 skyrocket, every angle of this aircraft has been fully revealed in front of countless camera lens, more high definition photos also appeared on the network, naHelp Desk Tracking Softwaretional military experts based on ground of a single point of analysis and evaluation of fuzzy photos made by, due to a large number of clear photos appear to have to make the amendment. body surface treatment staapplication business card creditndards of the top class-stealth capability, or Super-F-22 appears as one of the first high-definition photos, our amazing discoveries, and fuzzy photos of different previously, fuselage of fighter-20 takes on a delicate smooth, limousine-like surface of the mirror, which is unprecedented on the surface not only in the domestic fighter, is also a leading fighter in the world. This shows that flew into the manufacturing process and stealth coating application reached a very high standard. in dark blue grey camouflage coatings (valid for multiple spectrum is likely to be) under the cover, and rivet the fuselage and open edge is not entirely visible. After a series of complex processing on image, peer a few barely visible edges of the slit. Stealth technology and even Kings over the B-2 fighter-20 much, or even the notch. F-22 camouflage paint thinner is much like varnish, rivet, openings and edges of the surfaces are clearly visible. Although stealth coating is not thicker, more complex will advance, but such a thin layer of paint, showing clearly the flap, are clearly insufficient level of stealth's performance. surface treatment of F-22 stealth F-22 camouflage coatings, surface openings compared with fighter-20 has a gap, in addition to F-22 CARET inlet happens to be a standard cavity separating diaphragms of structure, strong reflection of the radar is far better than the so-called impact of canard fighter-20. Although you can use the absorbing coating mitigate, but weakness remains F-22 stealth. surface treatment-2 stealth stealth coating in overall appearance, slit processing, and deal with three major aspects of this stealth, fighter-20 clearly notch on F-22. Previously people's estimates may be biased towards conservative--the stealth fighter-20 standards are likely over the F-22, the worst level is quite--that is, positive RCS=0.1 square meters. (RCS, abbreviation of RadarCross-Section, Chinese interpretation of radar cross section area. ) took off less than 200 m? short takeoff capability stunning 2008 Pearl Navy show, canard fighter-10 shows the superior short takeoff capability, it took off running distance less than 280 metres, this used to be fans of the Chinese army was once exciting topics. According to witnesses at the scene description and spread online video measurement, the maiden flight of fighter-20 running only about 230 metres skyrocket--it is still prudent safety first, extremely conservative first flight. obviously, if you let go of what hands to play, Jian-20, within 200 metres off the ground it is entirely possible. Fighter-20 are shown here at the side of powerful engines, and duck wing under the combined action of the extreme effects of the rise. is can to carrier ship contains machine? since fighter-20 has excellent of short from takes off capacity, that is can like some Army fans of envisaged, fighter-20 can adapted for powerful of heavy ship contains machine, so members sea days does? needs note of is, fighter-20 overall select has high-speed configuration, especially which small exhibition string than of high-speed wing type, may makes its low altitude speed flight performance has lacks, for in complex sea conditions Xia into near landing in small of carrier deck Shang of needs,, aircraft with ship speed may partial fast, difficulty partial high. fighter-20 if you want to be converted into a carrier on the carrier, as envisaged by the F-22 Navy as required, airfoils in the aspect ratio of the high speed to the F-14 variable of type folding wings; or, as if it were F-35 Navy, and increase the wing. China and the next-generation fighters review we spent a lot of above coverage to elaborate on the various views of modern air combat, seem to digress too far away. But this is needed to understand fourth-generation fighter indispensable background for performance and capacity. after the insight into demand in air combat, we will be able to fourth-generation fighter "4S" sort of made more realistic and its weight. Order: supersonic flight capabilities, information acquisition capabilities, stealth and tactical combat performance. Finally, we, 40%, 20%, weights made of one generation fighters, United States and Russia of the integrated scores table. It is clear that here only the final conclusions, specific evaluation of the demonstration we will start in the next topic stealth techniques actually being touted as the United States Air Force stealth technologyBoasting to the point where the mystery of mysteries, and marvelous, as well as in hot pursuit of the public, media, stealth properties to hide the truth anymore. before analyzing the operational value of stealth aircraft, it is necessary to first review the stealth technology concepts. Stealth but a relative of the argument, is nothing more than weaken, inhibition, absorption, deflection of radar echo intensity targets, aircraft and radar system previously in force in the RCS value relative fall to a lower value, enabling one-way transparent, unidirectional battlefield combat. however, Spears and shields were racing each other and improve each other. Radar system in rapid progress, and because of its inherent advantages, radar system will be able to soon surpass stealth technology and stealth technology will encounter invisible walls, tread water. stealth aircraft to reduce the radar range, but limited according to the theory of radar, radar detection range and effectively target RCS's four-square (RCS open four times square) is proportional to the relationship. This theorem shows that to make the other radar detection range reduced to one-second, then your target RCS will be reduced to one-sixteenth. for fighters, RCS was reduced from more than 10 m to 1 square meters was relatively easy to do things (such as F/A-18E/F "Super Hornet" improved), we will continue to fall to 0.1 square meters, it takes a lot of stealth optimization tools (such as F-22 and numerous approaches fighter-20), to be reduced from 0.1 sq m went on, need more unconventional means, and difficult to further optimize (for example, B-2 bomber). in other words, the stealth, and in the struggle against stealth, the ultimate winner is radar. revolutionary onboard active phased array radar of third-generation fighters equipped with machinery is the first scan of pulse Doppler radar, then such as the MiG-31 fighter go equipped with passive phased array radar (PESA), or a passive phased array radar, whose main characteristic is through an electronic array antennas, enables electronic distribution and control of the radar waves, realizing a truly multi-targeted search and tracking capabilities. active phased array radar (AESA) or also known as active phased array radar is the emergence of a revolutionary step forward on the technology. It cancels the traditional Center of high power radar transmitters, and transmit/receive antenna (T/R) devices are combined, antenna every element is made up of GaAs microwave integrated circuits small modules, including the entire radar beam manufacture, launch, receive functions, is a miniature of the full radar. phased array radar, especially for active phased array (AESA) radar as compared to traditional mechanical scanning radar, function and performance are worlds apart, benefits to jinshu too far. For aircraft performance, and 2.1 of the most important is the ability to achieve a real goal, the second is the power to enhance. because AESA radar with transmitting/receiving element for efficient microwave integrated circuits (hereinafter referred to T/R module), the microwave energy loss is negligible for the same installation space (the same power and radome), AESA radar as of the effective radiated power of 10 times larger than the mechanical radar, detection range far 75%. advantages of AESA radar: part of module failures do not affect the overall performance, reliability of radar get leap; multiobjective multitasking features highlights, you can assign a different module combinations to perform different tasks, and so on. AESA of success application is on traditional airborne radar of once revolution, she on like computer from backward of DOS upgrade to colorful of Windows system, great to extended has radar of application area and improve has radar of work performance, turn improve and rich has combat aircraft implementation task of capacity and combat mode as long as radar power large, stealth fighter so obediently appareo fourth generation stealth fighter is can once made technology advantage of nature, is because previously of third generation fighter is equipped with of are is traditional of machinery scan radar, this radar General can in 70 km around distance detection to typical of 3-5 m RCS fighter target. RCS down to 0.5 0.1 square even stealth fighter, discovery of the radar distance down to about 20 km, distance is close Visual contact--and in practice long before the two sides close to this distance. Behind third-generation fighters are advanced four-generation warplanes launch long-range air-to-air missile shot down. however, in the presence of high power AESA radar, stealth fighter played no go, this type of radar on 3-5 RCS warplanes target discovery over distances of up to 160 or 200 kilometres, even stealth fighter RCS reduced to one-one hundredth, the radar detection range of 30 percent, there are still 6, 70 km, adequate guiding long-range air-to-air missile launch needs. stealth technology and relationships is a spear and shield, at which time they would form both sides are beyond effective range and found capable of in each other's abilities, the battlefield became "the bi-directional transparent" then stealth technology itself tactical significance of depreciation. ���ԣ���In stressed and rely on stealth fighter, like shaking wise, Maoni, playing for a while, play not go long. speed determine the outcome of important chips above says, after the fighters RCS down to the original 10%, discovery of the radar distance is reduced to only the original 56%. Even if the RCS is reduced to the original 1%, radar distances are reduced only to the original 32%. And improving radar performance easily, reducing the RCS, with the rapid development of radar technology, stealth aircraft's stealth ability became less and less reliable, so the estimated effects on the stealth technology should not be too high. if, in four generations of machines on three generations of air combat, can be obtained by virtue of the information is peer advantage takes up the opportunity, and calmly deal with privileges, then, four generations of fighters with advanced AESA radar is equipped with a three-generation fighters or when four generations of fighters fight, speed will determine the outcome of important chips. Energy principle is to maximize its speed of air combat (kinetic energy) and height (potential energy) and the rational use of this energy advantage, cutting height and speed advantage of competitors. [More] beyond visual range combat effectiveness is closely related to landing speed of margin is to launch the first landing speed is essential when you stop shooting missiles, air-to-air missiles of the effective range is not a constant, which at that time two machine height, speed, angle, location, target long on large level of tactical actions, and performance of the missile itself has to do. first of all, the dynamic range of the missile is capable to fly is closely related to landing speed, with a dynamic range of AIM-120 to reach 80 km/h, which launches landing speed to at least $ 1.4-1.6M, if when in subsonic launch, missile range is only about 65 km. Secondly, air-to-air missile launches the missile on the engine-driven after flight, but the missile engines generally only a dozen seconds, then glide missile depends entirely on the inertia, flying over the slowest. missile to hit the enemy must remain very strong for high speed mobile mobility. While working in rocket engines, missile power boost, their mobility is the strongest. When the missile is late when you coast, missiles with kinetic energy, but non-powered, missile to maneuver to pursue goals at this time, remaining kinetic energy missile will be quickly reduced mobility is greatly reduced. Air-to-air missile at the maximum range is usually unable to hit the target, even fighter-7 this type of aircraft can be able to avoid the AIM-120C of this type of advanced missile attack (of course also depends on the pilot's level). error: modern air combat missile is simple on the radio? air-to-air missile appeared, because some incorrect information, to create a lot of misunderstanding. That has now entered the era of extended range air combat, as long as the pilot pressed buttons, arrow of missiles such as takeoff automatically go straight to target hundreds of kilometers, the pilot turned calm body and back, called home.
