Hypersonic X-43A aircraft is the fastest airplane in the world. Apparatus X-43A has recently set a new speed record - 11 230 km / h, thus exceeding the speed of sound in 9.6 times. For comparison, the jet fighters flying at a speed of sound or above only twice.
Wingspan X-43A is 1.5 meters, length - 3.6 meters. Mounted on the engine it scramjet (Supersonic Combustion Ramjet) is an experimental supersonic combustion ramjet engine. Its peculiarity is that there are no moving parts, and used as a fuel mixture of hydrogen and oxygen. Moreover, oxygen is not stored in special tanks, and is taken directly from the ambient atmosphere, which can significantly reduce the weight of the machine. In no engine exhaust emissions, it is a common steam.
For this development the space agency NASA has been issued a certificate from Guinness World Records, which produces the famous Guinness Book of Records, confirming that this machine is the fastest airplane in the world.
The purpose of developing aircraft X-43A is a test of new technology, which is an alternative to hypersonic turbojet engines. According to scientists in the future hypersonic aircraft will be able to reach anywhere in the world for three to four hours.
