The future high-speed craft: New York to London as long as an hour
[abstract] the us air force test of hypersonic missiles off the coast of southern California has reached the speed of Mach 5, if used for commercial aircraft, so as long as 30 minutes from New York to Los Angeles, and general aircraft to fly 5 hours.
The U.S. air force test of hypersonic missiles off the coast of southern California has reached the speed of Mach 5, tests on Friday, X - 51 a hit, scramjet work for more than three minutes.
According to foreign media reports, the americans are being developed speed can reach more than 5 Mach of the hypersonic aircraft, according to the U.S. air force said, five years plan for hypersonic missiles into practical application.The technique may also be used for commercial, such as research and development of the hypersonic aircraft, from New York to London as long as an hour.Is currently testing a hypersonic missiles have been able to reach the speed of Mach 5.1, the U.S. air force has set up a deadline for this reason, in the five years to complete the practical application.The air force research laboratory supersonic material development director Kenneth Davidson believes the next five years we will make the technology mature gradually.
Hypersonic missile using a conventional warhead, rather than nuclear warheads, the main advantage is that use speed to win, to be able to launch in hundreds of kilometers away, the target attacking, pilots and aircraft platform can be safe and sound.Kenneth Davidson believes you can use a hypersonic missile attack high-value targets, in a very short period of time to eliminate it, because once found target reconnaissance force, if not immediately attack, it is easy to cause the loss target, lose track.The U.S. air force test of hypersonic missiles off the coast of southern California has reached the speed of Mach 5, tests on Friday, X - 51 a hit, scramjet work for more than three minutes.
The U.S. air force in the X - 51 a previous made progress gradually, spent $300 million used to study the scramjet, the hope that the technology can blow in a few hours to the earth's any one goal, found that destroyed.A top speed of Mach 5 is equivalent to 3500 miles per hour, in the tens of thousands of meters high, thin atmosphere can reduce air resistance.In addition to the U.S. air force, the department of defense advanced research projects agency (darpa) has a similar project, superior by gliding ballistic target for attack, prototype may be to 2018 or 2019 to test.
The pentagon officials with the U.S. air force research laboratory Ryan Helbach think in a foreign exhibition shows the various military research project, one of them is the advanced technology.Of course the United States is not the only country, the development of hypersonic technology as well as Russia and China have similar projects.Hypersonic blow is not only the advantages of fast speed, but also has higher precision strike, if used for commercial airliner, so as long as 30 minutes from New York to Los Angeles, and general aircraft to fly 5 hours.
