Experts NASA, MicroCraft Inc, Orbital Sciences Corporation created a hypersonic unmanned aircraft X-43A, which is today recognized as the fastest aircraft in the world. During testing, he showed fantastic speed - 11 230 km / h, which is almost ten times the speed of sound.
Wonder technique appeared after 10 years of rigorous research on supersonic ramjet engines that could accelerate aircraft to hypersonic speeds. And it spent about a quarter of a billion U.S. dollars, according to newsland.ru.
The fastest aircraft in the world is large. Wingspan - 1.5 m and a length of 3.6 meters. It installed an experimental supersonic combustion ram engine SCRamjet (Supersonic Combustion Ramjet). The main feature of this engine is the lack of moving parts. The fuel for the fastest aircraft used a mixture of hydrogen and oxygen. And as a result of using a mixture of hydrogen and oxygen, the result of normal engine operation is water vapor.
Scientists believe in the future hypersonic aircraft can reach any point on the globe in just three to four hours.
