Boeing's X-51A WaveRider — a jet-fueled, air-breathing hypersonic rocket — is one step closer to reality. In tests over Edwards Air Force Base in California, a B-52 bomber carried the X-51A WaveRider aloft for the first time, announced manufacturer Boeing Corp. The test was a key milestone in preparation for the X-51A to light its supersonic "ramjet" engine and propel the WaverRider at hypersonic speed for about 5 minutes, before plunging into the Pacific Ocean

In its first flight attempt, the X-51A WaveRider Wednesday completed the longest supersonic combustion ramjet-powered flight in history, flying nearly three and a half minutes at a top speed of Mach 5, although it fell short of its target duration and speed, according to Boeing. The unmanned aerial vehicle was released from a U.S. Air Force B-52H bomber off the southern California coast around 10 a.m. and flew autonomously for more than 200 seconds, powered by its Pratt & Whitney Rocketdyne supersonic combustion ramjet motor, transmitting telemetry data to ground stations, Boeing said in a news release. "Something then occurred...

LOS ANGELES (AP) — An unmanned experimental aircraft failed during an attempt to fly at six times the speed of sound in the latest setback for hypersonic flight. The X-51A Waverider was designed to reach Mach 6, or 3,600 mph, after being dropped by a B-52 bomber off the Southern California coast on Tuesday. Engineers hoped it would sustain its top speed for five minutes, twice as long as an X-51A has gone before. But the Air Force said Wednesday that a faulty control fin prevented it from starting its exotic scramjet engine and it was lost.

Here are the top five aerial weapons that one day could change the face of modern warfare. Relying on the most advanced technology in the world, these hyper-advanced projectiles may outmaneuver, outrun, and outmatch America’s foes around the globe, whenever the need arises. 1) The Mach-5 Cruise Missile If a cruise-missile at supersonic speed is a full-throttle Ford Mustang, then a missile that hits Mach 5 is a Formula 1 racer going all out. The problem is, that hypersonic Mach 5 pace — clocking in at five times the speed of sound– has yet to be reached by munitions. Until...

Boeing's HyFly hypersonic missile fails in bid for Mach 6 By Graham Warwick An attempt to fly a hypersonic cruise missile demonstrator at Mach 6 has failed, after the scramjet engine powering Boeing's HyFly malfunctioned and the air-launched vehicle plunged into the Pacific Ocean. The January 16 flight was the last under the HyFly programme, which was designed to demonstrate a missile-like vehicle with a range of 400nm (740km) and a maximum cruise speed exceeding Mach 6. The previous flight, in September 2007, failed to meet its objectives. The HyFly is powered by a dual-combustion ramjet (DCR) built by Aerojet....

coondoggie writes "The aspiration that jets may someday fly at over six times the speed of sound took a very real step toward reality recently, as the US Air Force said it successfully married the test aircraft, known as the X-51A WaveRider, to a B-52 in preparation for a Dec. 2 flight test. The X-51A flight tests are intended to demonstrate that the engines can achieve their desired speed without disintegrating. While the X-51 looks like a large rocket now, its applications could change the way aircraft or spaceships are designed, fly into space, support reconnaissance missions and handle long-distance...

The Space Shuttle may be dead, but the Air Force is looking to pick up the slack. Last month they launched their secret space plane, the X-37B, from a base from Florida. The spacecraft is currently on the first part of a top secret nine month mission that will end with a soft landing in California. So is the X-37B the Air Force's first foray into creating the world's first starfighter? Absolutely, not says the Air Force. Gary E. Payton, under secretary of the Air Force for space programs says that the plane carries "no offensive capabilities." He states, "The...

Sustained hypersonic flight above speeds of Mach 5 by vehicles using air-breathing, jet-fuel-powered engines could become achievable within the next dozen years. Successful recent ground tests of jet-fueled, ramjet/scramjet demonstrator engines by Pratt & Whitney Rocketdyne and Aerojet represent important progress toward flight-testing of three separate hypersonic-vehicle programs. In September, Pratt & Whitney Rocketdyne (PWR) completed 10 months' testing of a sub-scale combustor for a hydrocarbon-powered, dual-mode ramjet engine designed to operate over a wide range of Mach-number speeds -- that is, multiples of the speed of sound. Using JP-7 jet fuel, PWR ran the combustor successfully at a variety...

Hypersonic missiles Speed is the new stealth Hypersonic weapons: Building vehicles that fly at five times the speed of sound is amazingly hard, but researchers are trying ON AUGUST 20th 1998 Bill Clinton ordered American warships in the Arabian Sea to fire a volley of more than 60 Tomahawk cruise missiles at suspected terrorist training camps near the town of Khost in eastern Afghanistan. The missiles, flying north at about 880kph (550mph), took two hours to reach their target. Several people were killed, but the main target of the attack, Osama bin Laden, left the area shortly before the missiles...

Phantom Ray will pick up where the UCAS program left off in 2006 by further demonstrating Boeing’s unmanned systems development capabilities in a fighter-sized, state-of-the-art aerospace system. The Boeing UCAS program began with the X-45A, which successfully flew 64 times from 2002 to 2005. Those flights included a demonstration exercise with two X-45A aircraft that marked the first unmanned, autonomous multivehicle flight under the control of a single pilot...] ...Currently planned Dec. 2, the Air Force Flight Test Center’s B-52 will carry the X-51A to 50,000 feet over the Pacific Ocean then release it. A solid rocket booster from an...

Boeing's X-51 WaveRider has made aviation history by completing the longest ever supersonic* combustion ramjet-powered flight. The unmanned aerial vehicle (UAV) flew for almost three and a half minutes in the skies off the southern California coast on Wednesday, reaching an altitude of about 70,000 feet and hitting hypersonic (Mach 5) speeds. The X-51 WaveRider scramjet (supersonic combustion ramjet) is being developed for the Air Force Research Laboratory and the Defense Advanced Research Projects Agency (DARPA) by Boeing and Pratt & Whitney Rocketdyne. The goal of the program is to create a free-flying, scramjet-powered vehicle capable of operating continuously on...

PALMDALE - The next step in hypersonic flight test is under development in a hangar at The Boeing Co.'s facility at Air Force Plant 42. The unmanned X-51A "Wave­Rider" is a scramjet engine flight demonstrator, expected to provide flight test data at speeds beyond Mach 6 - about one mile per second - using its unique engine design. In a scramjet - or supersonic combustion ramjet - engine, air is scooped into the engine duct, then forced through a combustion chamber, where fuel is mixed in and ignited. This produces energy, which is forced out the rear of the engine...

I've had sources ask to meet me in some pretty odd places. But there was one meeting last year that had to be just about the strangest request yet. It wasn't just that this very-recently retired Defense Department strategist wanted to meet at the Pentagon City Mall -- that's a pretty common place to grab an off-the-record cup o' joe. It was where in the mall he had in mind: at the Nordstrom's coffee shop, tucked all the way in the far reaches of the store, just past the little kid's clothes section. So I walk past the rows of...

The dreams of being able to fly from New York to London in under an hour are once again put on hold, as the latest effort to fly at over five times the speed of sound has ended in failure. A US Air Force test of a missile that is supposed to travel at six times the speed of sound has ended in failure when the vehicle went out of control and crashed in the Pacific Ocean. It is still unclear what went wrong with the test flight. However, it joins a long list of failed hypersonic flights that shows...

Winnipeg Free Press - PRINT EDITION Hypersonic missile threat 'Carrier killers' could destroy U.S. Navy's supremacy at sea By: Tom Simko Posted: 01/8/2011 1:00 AM | Comments: 0 In a replay of cold war rivalries, a new missile race is shaping up but this time America and Russia are joined by India and China. All of these countries are rushing to develop hypersonic anti-ship missiles that threaten to reshape naval warfare and alter global balances of power. It's all about who can design the fastest missiles with the latest engine technology. American Tomahawk cruise missiles are powered by conventional turbofans,...

What's faster than a speeding bullet, doesn't require a cape and isn't deterred by kryptonite? It's called the X-51 Waverider...and is the latest creation of Boeing and Pratt and Whitney Rocketdyne. This past May it completed the longest hypersonic combustion (scramjet) powered flight in aviation history, reaching a speed of about Mach five, or five times the speed of sound. A scramjet engine is often likened to an air-breathing engine...it has no moving parts, and sucks in air from the atmosphere, rather than using oxidizers or additional fuel. It is new technology engineers say will allow aircraft to fly faster...

A recent United States Air Force scramjet test has hinted at a future where hypersonic vehicles streak through the sky at many times the speed of sound around the world, and perhaps even open up access to space. The experimental X-51A Waverider used a rocket booster and an air-breathing scramjet to reach a speed of Mach 5 and achieve the longest hypersonic flight ever powered by such an engine on May 26. That technology might not only deliver cargo quickly to different parts of the globe, but could also transform the space industry and spawn true space planes that take...

Following the longest flight yet by an air-breathing scramjet engine, the X-51A Waverider team is waiting to see whether the largely successful first launch of the hypersonic demonstrator will unlock funding for further development of the ­technology. The X-51A was launched over the Pacific on May 26, achieving scramjet ignition and acceleration, but the engine ran for only 200 sec. rather than the 300 sec. planned, and the vehicle reached around Mach 5 instead of accelerating beyond Mach 6. When it began to slow down and telemetry was lost, the flight was terminated and the vehicle destroyed, says Charles Brink,...

An aircraft resembling a large bodyboard detached from a flying B-52 bomber and then shot across the Pacific on Wednesday at more than 3,500 mph, shattering aviation records and reigniting decades-long efforts to develop a vehicle that could travel faster than a speeding bullet. The unmanned X-51 WaveRider, powered by an air-breathing hypersonic engine that has virtually no moving parts, was launched midair off the coast near Point Mugu. It sped westward for 200 seconds before plunging into the ocean as planned. Previous attempts at hypersonic flights lasted no more than 10 seconds. "Everything went very well for a first...
