Unmanned US Army hypersonic aircraft fails

As per the latest reports released by the US Air Force on Wednesday, an unmanned American experimental aircraft failed in a hypersonic test flight. Later, the hypersonic aircraft fell into the Pacific Ocean.

The unmanned aircraft was named as ‘X-51A Waverider’. The unmanned aircraft failed to reach the speed of Mach 6 [about 7,300 kmph].

In a statement issued by the US Air Force, it said, “The craft successfully separated in midair from a B-52 bomber served as mother ship, and the rocket booster fired as planned.”

It is said in reports by the US officials that about 16 seconds into the test flight, a drawback was noticed with one of the curiser control fins.

Talking to media, X-51A program manager, Charlie Brink said, “It is unfortunate that a problem with this subsystem caused a termination before we could light the scramjet engine.”

In the meantime, the X-51A Waverider, also known as scramjet, was designed to fly for 300 seconds, and this was the third try by the US Air Force at getting an X-51A airframe to go hypersonic.
