Andrei Chang leaks again: to fly the second of four generations casting [Commentary] Maj. strongest team played East China
United States, "Aviation Week" magazine website on November 1, published its latest issue of the journal's cover article, for the first time disclosed the SR-72 reconnaissance unmanned hypersonic research project is being conducted in secret U.S. Lockheed Martin. According to reports, SR-72 hypersonic unmanned reconnaissance aircraft is mainly used to replace the 1970s developed the SR-71 "Blackbird" high-speed high-altitude reconnaissance aircraft, the maximum flight speed of Mach 6 to a staggering (that is, the speed of sound 6 times), and even the flying faster than some of the common missile, called the human-made, "the fastest aircraft." Because of its speed advantage, hypersonic aircraft air defense system to the current pressure is great, some of the famous air missile, such as the U.S. "Patriot", Russia's S-400 and China's HQ-9 can not even keep up with this aircraft, so it can not be intercepted and shot down. Some scholars have pointed out that China must be developed as soon as possible hypersonic aircraft missiles and laser anti-aircraft weapons to deal with, otherwise, casting when the SR-72 passing Chinese casting airspace, we can only "hope machine sigh." Former U.S. SR-71 high-altitude high-speed reconnaissance aircraft, known as the world's fastest aircraft to fly, but also during the Cold War was not the only military aircraft shot down. This is mainly due to the SR-71 is a type of flight altitude up to 30,000 meters, at speeds up to Mach "double 3" 3 aircraft, but it also uses the first stealth design, all of which enable it to easily escape any country's air defense system. Allegedly, it must fly higher than the existing vast majority of fighters and anti-aircraft missiles, fly faster, and out of enemy airspace, such as unhindered. It is believed that the aircraft can be completed within one hour on an area of 600,000 square casting kilometers of area optical photographic reconnaissance missions, the image that it only takes 16 minutes to get to shoot high-resolution photos covering the entire casting Chinese territory, And do not worry about being shot down by Chinese Defense Force problems. While this reconnaissance is very advanced, but its implementation mission due to maintenance costly, casting making the U.S. military had to be retired at the end of the century. In recent years, the U.S. military began to regard China as a competitor, the military had earlier heard To re-enable the SR-71, China's defense network to thwart China's "strategic refused only" for a breakthrough. However, SR-71, after all, is the old aircraft, although its speed is still amazing, but not necessarily be able to escape military service in recent casting years, the pursuit of new air defense missile, and aircraft maintenance costs are very alarming, it may not have made the U.S. do not think twice. Especially with the progress of the U.S. hypersonic aircraft technology, casting the ramjet technology has matured, which laid the foundation for the development of a new generation of U.S. military hypersonic reconnaissance aircraft. Allegedly, the support of the HTV-3X "black swallow" project, the U.S. developed a lower ignition speed (less than Mach 3) The scramjet, so, SR-72 hypersonic unmanned reconnaissance turbojet aircraft will use a combination of body and scramjet engine as power, turbojet aircraft accelerated to Mach 3, the scramjet ignition continue to accelerate to Mach 5-6. And China is currently the most advanced anti-aircraft missile is a red flag -9, this maximum speed of Mach 4.2 missile, that when the United States and SR-72 reconnaissance aircraft using hypersonic unmanned hypersonic cruise flight, China's casting air defense missiles will catch up. Meanwhile, the red flag -9 sustain 4.2 Mach speed flight time is only about 120 seconds, while the SR-72, casting you can take the whole hypersonic flight in the investigation into the airspace, so the red flag -9 hit chance SR-72 is almost zero . If these allegations are true, then it means that China's casting airspace will be nearly 20 years later, anti-aircraft again suffered humiliation. However, from the reports of view, SR-72 will be around 2018 prototype casting test, in service around 2030, so China still has the opportunity to rise sniping. It is reported that China not only has built up to nine times the speed of sound hypersonic wind tunnel, but also after the United States seeking to develop hypersonic aircraft, which also contains a high velocity air defense missile projects. The rise of China is now full field development rate, if the U.S. SR-72 will be in service around 2030, then, China should be developed after 2025 the maximum flight speed of up to 8 times the speed of sound in air defense missiles. It is safe to say that even if SR-72 served as scheduled, China to deal with it from time to stop at a antiaircraft missiles. It is said that high-energy laser weapons projects in China, but also well into the fast lane, which had been used to intercept enemy ballistic missile test. And on the speed, the vast majority of ballistic missiles at the end of more than 10 times the speed of sound are therefore used to deal with hypersonic aircraft there is no difficulty. So, as long as it dared to infringe on China's airspace, casting the Chinese secret development of advanced weapons would wait more than its arrival in 2030!
