Shocked! .Ultimate weapon the United States over China's third appearance at first glance _zhangna0710.

The U.S. military recently a successful test flight in the California desert has a "Global Observer," the new form of unmanned reconnaissance aircraft. .Reportedly, the "Global Observer" size is very large, with a wingspan equivalent to a Boeing 747; flight level equivalent of two Mount Everest. .The Pentagon noted that the "global observer" would completely change the military space of the "rules of the game." .(ABC, United States, "Defense News", "Defense Industry Daily", "Aviation Week"), called "Global Observer" aircraft from the United States, California, "Environmental Air" (AeroVironment), Inc, a volume ratio of a .bigger Boeing 767 aircraft can be up to 65,000 feet (19,812 meters) in the stratosphere, which is equivalent to an altitude of Mount Everest two, beyond the range of most anti-aircraft missiles and a range of observations. .It can see the radius of 600 miles (about 960 kilometers, an area that is seen is 289 million square kilometers, equivalent to about 1 / 3 of China) range of features, enough to cover the whole of Afghanistan. .Research and Engineering Services is responsible for the U.S. Assistant Secretary of Defense Lyme Munoz described on the ABC: "This will change our view of aviation. It will carry out a new future." Precedent for creating liquid hydrogen fuel, "Global .Observer "relies entirely on liquid hydrogen fuels, so that it can continue flying for one week longer than any and all aircraft are currently enduring. ."Environmental Air" CEO Confer Edwards Air Force Base in California hangar said in an interview: "It is the hydrogen fuel, its energy density is 3 times of gasoline, it can fly at a lower cost more .long, and is zero emissions. "It is understood that" global observer "will only emit water vapor. ."Environmental Air" Deputy Stephen. .Gitlin said liquid hydrogen as the fuel chosen, because "it is two times higher density than other fuels." .In other words, a pound of hydrogen fuel to provide the flight length, twice as many than in the general fuel. .However, at least so far, storage of liquid hydrogen has always been a major obstacle. .It requires a heavy, insulated containers, which appears to the requirements of light aircraft and unmanned long-endurance are not compatible. .But the "environmental air," said the company has resolved the problem. .Gitlin said: "We have developed into an innovative way to solve the problem of heavy container. At present, the problem is not the container." Hydrogen enter the internal combustion engine, the hydrogen internal combustion engine combined with oxygen from the air. .Gitlin said that to do so is difficult, because the 65,000-foot altitude, the air is very thin. .Details of the internal combustion engine, including weight, power production and manufacturing materials, are company secrets, but is known that the internal combustion engine generator will provide power to drive the propeller. .Generator will also produce 2.8 kilowatts of electricity for communications equipment, cameras and other sensors used. ."Global Observer" not high-speed flight. .But can be accelerated to 65,000 feet in the air to meet strong wind. ."Global Observer" with strong, lightweight synthetic material to cause such a structure is to facilitate disassembly, put into transport aircraft to deploy to a distant area of operations. .Gitlin said, "Global Observer" to the ordinary American aircraft runways, its weight and large SUV, just as it can carry 380 pounds of equipment. .Cheap to replace the satellite "global observer" can be more cheaply to the effectiveness of the satellite, the cost of only $ 30,000,000, while the cost of the satellite need to be hundreds of millions or even one billion U.S. dollars. .However, and satellite different is that this plane can act within hours and can be readily converted position. ."Global Observer" along the top of each can target orbit in a week, similar unmanned reconnaissance aircraft can only stay for 30 hours. .Machines in addition to ongoing monitoring of the camera lens, as well as in the same wireless telephone, television and broadband Internet access and other telecommunications equipment and services. .U.S. forces will be able to lower the cost of any region in the world to shoot and communications. .Refueling aircraft, there will be another airplane instead of its location. .Military aircraft will be a weekly rotation to carry out continuous surveillance. ."Environmental Air" just one of many attempts to solve the problem of height and one of the long voyage. .In July, Boeing announced a new production of the company's high-flying, long endurance, unmanned aircraft, hydrogen fuel, called "Phantom of the eye." ."Phantom of the eye" wings 150 feet in length, can carry 450 pounds of weight, but only about 4 days of sustained flight. .Seeing over a third of China "/>.
