    USAF's hypersonic plane fails in second test flight

    EDWARDS AIR FORCE BASE, CALIFORNIA (BNS): The second test flight of US Air Force’s experimental hypersonic aircraft, X-51 WaveRider, has ended in failure, the US media reported Friday.

    The mission involved a B-52 bomber which was to release the aircraft at an altitude of 50,000 feet off the Pacific coast.

    The B-52 bomber carrying the WaveRider took off from the Edwards Air Force Base in California on June 13 Monday.

    Once the bomber reached the height of 50,000 feet near Point Mugu, it released the hypersonic plane “and it fell like a bomb for about four seconds before its booster rocket engine ignited and propelled the aircraft,” the Los Angeles Times reported.

    The aircraft was supposed to get separated from the bomber and speed across the sky, powered by an air-breathing combustion engine, but that didn’t happen.

    “A momentary lapse in airflow to the engine caused a shutdown and the X-51 plunged into the ocean within the test range,” the news report said.

    Engineers are evaluating the data collected during the test flight to identify the cause of the problem, it said quoting the Air Force.

    “Obviously we're disappointed and expected better results,” Charlie Brink, the Air Force X-51 programme manager, said in a statement. “But we are very pleased with the data collected on this flight.”

    The USAF had conducted the first test flight of the X-51 WaveRider on May 26, 2010. The maiden flight had lasted for over 200 seconds, the longest ever hypersonic flight powered by scramjet propulsion.

    The WaveRider, built by Boeing and Pratt and Whitney Rocketdyne, reached an altitude of 70,000 feet and a top speed of Mach 6. However, a vehicle anomaly led to the termination of the flight after 200 seconds.

    The hypersonic plane is being designed to hit distant targets anywhere in the world within few minutes. It could also substitute for a ballistic missile armed with conventional warhead.

    US to test third X-51 hypersonic cruise missile

    [​IMG]

    ==


    A third Boeing X-51 hypersonic test vehicle will fly shortly, a senior company official says.

    "We're planning to fly another vehicle shortly," says Joe Vogel, Boeing's hypersonics director. The test vehicle will fly as soon as the government gives its assent. "It'll be this year."

    That would be the missile-like test vehicle's third flight. Two earlier tests successfully demonstrated hypersonic flight, but the air vehicles did not fly for as long a duration as was expected.

    "I consider it successful," Vogel says of the truncated previous flights.

    Vogel notes that the first flight set a world record for duration at hypersonic speed while the second flight ended with a controlled landing into the ocean.

    There is also a fourth test vehicle available to the programme. If the third flight proves to be completely successful, that remaining test article could be used for materials testing or testing different flight profiles, Vogel says.

    Boeing is working on the supersonic combustion ram jet, or scramjet, with the Defense Advanced Research Projects Agency (DARPA), US Air Force Research Laboratory and Pratt and Whitney Rocketdyne.

    If successful, the endeavor could yield new missiles, aircraft and space-launch vehicles, Vogel says. A flight from New York to Los Angeles could take less 39 minutes at Mach 5, he adds.

    The US has been struggling with the X51 for some time now, but Bramhos corp is confident of inducting the missile by 2015/16. And we have not even started testing yet. Quite strange. DRDO must have learnt a thing or two with the Shaurya.

    fzaq, here is a video.

    Re: US to test third X-51 hypersonic cruise missile

    X-51 is not a cruise missile but a test vehicle, More like a test bed for upcoming missiles or vehicles.


    A lot of things are not unvield about X-51 like its max range and duration time.

    India's hypersonic vehicle (HSTDV) looks similar to it.

    US hypersonic aircraft crashes seconds into military test flight

    LOS ANGELES: An unmanned experimental aircraft designed to fly six times the speed of sound broke apart over the Pacific Ocean seconds into a military test flight due to a faulty control fin, the US air force said on Wednesday.

    The problem with the fin on the craft known as the Waverider or X-51A was identified in a test flight on Tuesday, 16 seconds after a rocket booster on the remotely monitored craft was ignited to propel it forward, the air force said in a statement.

    Fifteen seconds later, when the X-51A separated from the rocket booster, it lost control due to a "faulty control fin," the statement said. The 31 seconds of flight fell far short of the military's goal for the X-51A to fly for five minutes.

    The aircraft broke apart immediately and fell into the Pacific Ocean near Point Mugu northwest of Los Angeles, said Daryl Mayer, a spokesman for the 88th Air Base Wing at Wright-Patterson air force Base in Ohio.

    Even if the test had been a success, the aircraft would have crashed at the end of the flight in any case and was not considered retrievable.

    The Waverider was designed to reach speeds of Mach 6 or above, six times the speed of sound and fast enough to zoom from New York to London in less than an hour. The military has its eye on using the Waverider program to develop missiles with non-nuclear explosives that could strike anywhere in the world within an hour, analysts said.

    The cost of the experimental aircraft, which military officials said was dropped from a B-52 bomber before its rocket booster was ignited, has not been disclosed because many details of the program are classified.

    The aircraft is known as the Waverider because it stays airborne, in part, with lift generated by the shock waves of its own flight. The Boeing Co's Phantom Works division performed design and assembly on the craft, the military said.

    The fins on the rocket booster kept the aircraft on-course during the initial phase of the flight, despite the problem with the control fin on the X-51A itself, Mayer said.

    A Boeing spokeswoman declined to comment on the test flight, citing an air force request to have all public communication come from the military.

    Future X-51A flight

    This was the third of four X-51A aircraft built for the military, one of which flew for over three minutes at nearly five times the speed of sound during a 2010 test flight, the air force said in a statement.

    The air force, which is analyzing data from Tuesday's test flight, said one X-51A aircraft remains and that a decision has not been made "when or if that vehicle will fly at this time."

    The Waverider is part of efforts by the US military to develop a prompt global strike capability to hit targets anywhere in the world within an hour, said Guy Ben-Ari, senior fellow with the Center for Strategic and International Studies.

    Over the years, the global strike program will likely eat up billions of dollars in development costs, Ben-Ari said. If the program becomes operational, targets could include conventional military sites or militants, he added.

    A missile would likely not be fired from a vehicle like the X-51A, but the craft itself would be the missile, he said.

    "The differences between what's an aircraft and what's a missile and what you would call a drone or a remotely piloted vehicle are becoming very fuzzy," Ben-Ari said.

    That the test flight crashed early due to a problem with a fin would likely be frustrating for the military because that part was relatively easy to build, unlike the largely untested Scramjet engine, said John Pike, director of GlobalSecurity.org, a website for military policy research.

    "The only way that you can develop this stuff is to actually take it out and fire it, and so the problem is they've got computer models but not much data," Pike said.

    Pratt & Whitney Rocketdyne designed the X-51A's "Scramjet" engine, which uses the forward motion of the craft to compress air for fuel combustion, according to a description of the project from the military.

    "It is unfortunate that a problem with this subsystem caused a termination before we could light the Scramjet engine," Charlie Brink, X-51A program manager for the air force research laboratory, said in a statement.

    "All our data showed we had created the right conditions for engine ignition and we were very hopeful to meet our test objectives," Brink said.
