Plane breaks record

2010-05-27 14:31

Washington - An experimental aircraft has set a record for hypersonic flight, flying more than three minutes at Mach 6 - six times the speed of sound.

The X-51A Waverider was released from a B-52 Stratofortress off the southern California coast on Wednesday morning, the Air Force reported on its website. Its scramjet engine accelerated the vehicle to Mach 6, and it flew autonomously for 200 seconds before losing acceleration. At that point the test was terminated.

The Air Force said the previous record for a hypersonic scramjet burn was 12 seconds.

"We are ecstatic to have accomplished many of the X-51A test points during its first hypersonic mission," said Charlie Brink, an X-51A programme manager with the Air Force Research Laboratory at Wright-Patterson Air Force Base, Ohio.

"We equate this leap in engine technology as equivalent to the post-World War II jump from propeller-driven aircraft to jet engines," Brink said.

The Waverider was built for the Air Force by Pratt & Whitney Rocketdyne and Boeing Co.

"This is a new world record and sets the foundation for several hypersonic applications, including access to space, reconnaissance, strike, global reach and commercial transportation," said Joe Vogel, Boeing's director of hypersonics.

Four X-51A cruisers have been built for the Air Force, and the remaining three will be tested this year.

"No test is perfect," Brink said. "And I'm sure we will find anomalies that we will need to address before the next flight."

    If the speed of sound is about 330 meters per second, then at Mach 6 the aircraft were covering almost 2km per second. For 200 seconds that is about 400km! That is awesome, I want one!

    That's nothing, my corsa already went that speed during the december holidays.

    please add a picture of the plane, im sure we would all like to see it

  • Record already set at Mach7 - 2010-05-27 16:23

    The NASA website says: 'On August 16, 2002, the University of Queensland in Australia completed the first successful flight of a scramjet vehicle, reaching speeds of Mach 7, or seven times the speed of sound.'
