fox news - Rare footage of China's £5 million hypersonic wind tunnel
Chinese scientists have claimed to be able to make more discoveries than their American counterpart in developing supersonic aircraft thanks to better equipment.A secretive £5 million hypersonic wind tunnel, nicknamed 'Hyper Dragon', is helping the experts 'reveal many facts that Americans have not found out', one Chinese researcher said in a propaganda documentary.The programme also revealed that Chinese scientists are developing a commercial plane that could connect Beijing and New York in just two hours.Shrouded in secrecy, the JF12 shockwave hypersonic wind tunnel was completed in May, 2012, but has rarely been captured by media.China Central Television, the state broadcaster, showed a glimpse of the mysterious equipment in a documentary on October 8.Built by Chinese Academy of Science with 46 million Yuan (£5 million), the 2.5-metre-wide (8.2feet), 265-metre-long (869 feet) tunnel is said to be able to blow gusts of wind as fast as 10 times the speed of sound.The temperature of the gusts could reach a staggering 3,000 degrees Celsius.Jiang Zonglin, a researcher from the Chinese Academy of Science, called the 'unprecedented' wind tunnel an incubator of advanced aircraft.Mr Jiang said because planes couldn't fly during a lab experiment, they would need a wind tunnel that could generate gusts as fast as the desired speed of the aircraft to simulate a flying environment.In the case of JF12, it could simulate flying conditions between Mach 5 and Mach 9.Mr Jiang claimed that he and his team carry out one experiment every two days, and each experiment last 100 millisecond, which equals to one-tenth of a second.The researchers pointed out that China is currently developing a supersonic commercial plane that could travel as quickly as five times the speed of sound.This means the aircraft would be able to fly from Beijing to New York in two hours, compared to the current 14 hours.The TV clip apparently also shows an arrowhead-shaped model inside the Beijing-based wind tunnel.Its design looks like official Chinese mock-ups of the DF-ZF, China's 7,680mph hypersonic strike aircraft that could carry nuclear warheads past US missile defenses.Chinese officials have confirmed several test flights of hypersonic glide vehicles since 2013, but have kept the details top secret.This is likely the first time China has shown any test models linked to the project.In addition, The broadcast showed a weapon with a shape similar to the last stage of a ballistic missile, and computer generated images of a new triangular-framed glider.Raymond Wang, an expert in stopping the international spread of nuclear weapons, from the Middlebury Institute of International Studies at Monterey, California, was one of the first to spot the DF-ZF model.Writing on Twitter, he noted the programme's narrator didn't specifically refer to hypersonic boost-glide vehicles (HBGVs) or the DF-ZF at any point.'China just showed its hypersonic-BGV in a vid on 08 Oct.Probably a test design model, bu
The class of drugs that Levitra, Viagra, Stendra, and Cialis belong to are called PDE5 inhibitors. They work by relaxing tight blood vessels, allowing more blood to surge into the penis and cause an erection, says Gregory Bales, M.D., an associate professor of urology at the University of Chicago.
The little pills do the trick for more than two-thirds of men with Viagra protects the heart (ED). They also work for guys who simply need them for a short time to get their “confidence back,” says Michael Eisenberg, M.D., director of male reproductive medicine and surgery at Stanford University.
