VSS Enterprise maiden flight

British billionaire Richard Branson's dream of space travel that thousands of people can afford took a leap toward reality with the maiden flight of the world's first commercial spacecraft over California's Mojave Desert.



Branson's company Virgin Galactic announced Monday that the VSS Enterprise had successfully completed what it called a captive carry flight attached to a carrier plane.

The spacecraft's developer called it a "momentous day."

"The captive carry flight signifies the start of what we believe will be extremely exciting and successful spaceship flight test program," said Burt Rutan, founder of Scaled Composites, which built the spacecraft.



The VSS Enterprise remained attached to its carrier aircraft for the duration of the 2-hour, 54-minute flight, reaching an altitude of 45,000 feet, according to a statement from Virgin.

Eventually, the 60-foot long rocket plane will be taken 60,000 feet above the Earth by its carrier and fire rockets to propel itself into space.

The test-flight program is expected to continue through 2011, going first to a free glide and then to a powered flight before commercial flights begin.

"Seeing the finished spaceship in December was a major day for us but watching VSS Enterprise fly for the first time really brings home what beautiful, ground-breaking vehicles Burt and his team have developed for us," Branson said.

"Today was another major step along that road and a testament to U.S. engineering and innovation," he said.

Virgin Galactic has envisioned one flight a week, with six tourists aboard. Each will pay $200,000 for the ride and train for at least three days before going. About 80,000 people have placed their names on the waiting list for seats.

"What we want to be able to do is bring space travel down to a price range where hundreds of thousands of people would be able to experience space, and they never dreamed that [they] could," Branson said last year.

He has said he hopes the technology will lead to a new form of Earth travel, jetting people across oceans and continents faster through suborbital routes.

"As far as we are concerned all pre-conditions have been met and the funds are available," said Peter Hintze, parliamentary state secretary at the ministry of economics.

His statement implied that the conditions were in line with World Trade Organisation rules.

Hintze said that "final issues" would have to be solved, notably how to divide up work between France and Germany on another project, the A30X, a potential successor to the A320.

"We want to be sure that (A30X) research and development will be done in Germany," he said.

The A30X's completion is widely expected to take place in Hamburg, northern Germany.

"We want an agreement quickly," he said. "We want to wind up the negotiations in spring."

Airbus, a division of the European aerospace giant EADS, intends to launch the A350 as a rival to Boeing's 787 Dreamliner.

The Airbus A350 XWB (extra-wide body) is described by the company as an eco-friendly passenger aircraft that can seat between 270 and 350 passengers.

Able to run on less fuel than current planes, its development is supported by four partner nations -- Britain, France, Germany and Spain.

France has announced support of 1.4 billion euros for the 12-billion-euro programme and Britain around 400 million.

The Spanish government remains in discussions with Airbus over its funding offer but reports say it could be around 300 million euros.

Hypersonic X-51 Waverider

The U.S. Air Force is gearing up for the first of four planned test flights of a hypersonic aircraft designed to operate for much longer durations and cover far greater distances than previous platforms of its type.



The maiden flight of the X-51 Waverider aircraft — the first U.S. hypersonic vehicle to fly in six years — is scheduled to take place later in March. Boeing Defense, Space & Security Systems of St. Louis has been developing the aircraft since 2003 on behalf of the Air Force Research Laboratory and Defense Advanced Research Projects Agency.

The missile-shaped X-51 will be carried aloft under the wing of a B-52 bomber, Joe Vogel, Boeing's director of hypersonics, said in a Feb. 22 interview. It will be released from the jet over the Pacific Ocean and drop for four seconds until its rocket motor ignites and accelerates it to about 5,800 kilometers per hour, just shy of the widely accepted start of hypersonic flight at Mach 5, or about 6,100 kilometers per hour. At that point, its air-breathing scramjet — or supersonic combustion ramjet — engine, built by Pratt & Whitney Rocketdyne of Canoga Park, Calif., will kick in, shooting the craft to Mach 6, or more than 7,400 kilometers per hour.

Grand plans for hypersonic vehicles have been around for decades, but their goals were often unrealistic and not matched by budgets, resulting in failure. The approach on X-51 has been to demonstrate the technologies that could one day enable things like single-stage-to-orbit vehicles.

"Theoretically you can probably get there someday, but trying to do it all at once with not enough money is very, very challenging," Vogel said.

Potential applications for hypersonic technology are superfast airplanes, missiles and reusable space launch vehicles, Vogel said. While the technology is not ready to ferry passengers from New York to Los Angeles in under an hour, such a scenario is not all that far-fetched, Vogel said. The upcoming demonstrations should show that the technology could be used in a next-generation missile program, he said.

Boeing has 42 people working on the X-51 program, down from a peak of about 90 people in 2007. Pratt & Whitney Rocketdyne's team peaked around 60 people and is now down to nine people, Vogel said.

Boeing also built the United States' previous hypersonic flight demonstrator, the X-43A, on behalf of NASA. The X-43A program made two successful flights in 2004: an 11-second flight that reached Mach 7, and a 10-second flight that approached Mach 10 and set a new record for fastest flight by a jet-powered aircraft. Both vehicles were designed to plummet into the ocean and be destroyed.

Scramjet engines like those on the X-43A and X-51 must be accelerated to very high speeds to deliver compressed air to their combustion chambers. Both crafts rely on rocket propulsion to create this initial speed.

While the X-51 will not reach the top speed of its predecessor, it is intended to demonstrate more operationally realistic technologies, Vogel said. Whereas the X-43A used a highly energetic hydrogen fuel, the X-51 uses the same JP-7 fuel that powered the SR-71 surveillance aircraft, and its engine could be adapted to use other hydrocarbon-based fuels, he said. The X-51 is expected to fly about 900 kilometers under jet power in about five minutes, 30 times longer in duration than the X-43A flights.

Boeing has built four X-51 aircraft for the upcoming test campaign. Though none will be recovered after its test flight, their liquid-cooled scramjet engines have shown in ground testing to be very durable, Vogel said. The X-43A engine was not actively cooled and was not intended for reuse.

"This [the X-51] engine has been tested extensively in the laboratory, and it's come out and been reused multiple times," Vogel said. "In theory, if we had more time and more money and more space in the vehicle, we probably would have put a recovery system into it. Future vehicles could have a recovery system, and we have started looking at ways to recover the engine."

The government does not currently plan to support the X-51 program beyond the four identical flight tests, which should be complete by the fall, Vogel said. Boeing has proposed a next phase of the program to the government, but he declined to be specific.

Since 2003 the government has spent about $250 million on the X-51 program, Vogel said. Air Force Research Laboratory spokesman Derek Kaufman was unable to provide funding details by press time.

Vulture UAV

Vulture UAV by Jim Wilson/Lockheed Martin



Class: High-Altitude

Habitat: A belt of relatively calm air around 55,000 feet

Behavior: Lockheed Martin’s design for Darpa’s Vulture program can stay aloft for five years, turning lazy circles above any patch of ground that needs continuous monitoring. A suite of day-and-night cameras can scan a 600-mile swath, sending data back to handlers on the ground. The craft will have to beat out species from a Boeing-led consortium and Virginia-based Aurora Flight Sciences for a second round of funding.

Notable Feature: The craft’s semiflexible structure bends instead of breaking when winds cause the long span to oscillate violently

Embla UAV

Embla UAV by Aesir

Embla UAV

Class: Hovercraft

Habitat: Afghanistan and disaster zones, starting in June, according to British manufacturer Aesir. About the size and shape of a spare tire, the Embla lifts straight up from the ground without the need for a runway, making it more useful to combat soldiers stationed in rough terrain. Its diminutive size lets it zoom down urban canyons to find hard-to-reach enemy hideouts, and it can send video to a remote PDA-size controller, revealing potential ambushes. Loaded with explosives, it could even enter an enemy compound on a suicide mission. Yet it’s not exclusively a military breed—Embla’s maneuverability makes it a good scout in emergency scenarios too dangerous for humans to enter.

Behavior: The Embla can change direction on a dime, fly at 50 mph, and climb to 10,000 feet. It also has the ability to hover in place to, for instance, transmit encrypted HD video. Notable Feature: Whereas a ducted fan funnels air straight down to generate lift, the Embla’s turbine sucks air in through its top and forces it out through a skirt-like wing. This design bends the flow toward the ground. This makes Embla strong enough to carry cameras, weapons and sensors on its belly, oriented toward the terrain it’s watching.

Ion Tiger UAV

Ion Tiger UAV by Naval Research Laboratory, Washington, D.C.

Ion Tiger UAV

Class: Endurance

Habitat: European airfields, potentially, from which it could reach the Middle East, once the Navy perfects the fuel-cell technology inside. It could fly as low as 1,000 feet without being heard on the ground, or as high as 14,000 feet.

Behavior: Its ability to stay aloft for 24 hours allows the Ion Tiger to encroach on the terrain of much bigger birds, such as the Predator, and its small size lets it get closer to a target to shoot footage with its lighter, cheaper camera.

Notable Feature: Its carbon-wrapped aluminum hydrogen tanks weigh only about nine pounds each, which helps this UAV stay airborne longer.

Excalibur UAV

Excalibur UAV by McArdle Productions

Excalibur UAV

Class: Hunt-and-kill

Habitat: Future war zones, on land and at sea. If Aurora Flight Sciences can scale up the prototype, Excalibur could be deployed on the battlefield within five years.

Behavior: Unlike Air Force drones, which are flown by operators stateside and are in short supply, the Excalibur can be remotely operated from wherever it’s deployed—the mountains of Afghanistan or the helipad of a ship—providing immediate tactical support to Army, Navy and Marine troops. It can take off and land without a runway and flies at 30,000 feet. Fitted with 400 pounds of laser-guided munitions, including Hellfire missiles, the hybrid turbine-electric Excalibur strikes enemy targets up to 600 miles away from its handler. It can loiter and inspect the damage with a suite of infrared or electro-optical surveillance cameras and follow anyone who gets away.

Notable Feature: After takeoff, the jet engine pivots in-line with the fuselage, and the lift turbines retract inside the wing section for forward flight. It travels at a brisk 530 mph—twice as fast as a helicopter.

RQ-4 Global Hawk  UAV

Habitat: High above Iraq, Afghanistan and Pakistan—or anywhere else the U.S. Central Command wants to keep under watch.

Behavior: Soaring at 65,000 feet with an endurance of 36 hours, the Global Hawk can keep watch over 40,000 nautical square miles per mission. Carrying a full suite of electro-optical, infrared and synthetic aperture radar sensors, it can operate day and night in all weather conditions. The larger variation has a 130-foot wingspan.

Notable Feature: The fact that it can take off and land autonomously greatly reduces the potential for crashes, which have handicapped the Predator and Reaper.

Mantis UAV

Mantis UAV from Ronen Nadir/Bluebird Aero Systems


Class: Autonomous

Habitat: Up to 40,000 feet above any battlefield, disaster site or border, relaying intelligence data back to controllers on the ground

Behavior: All a soldier will have to do to send the self-piloted Mantis on a mission is push a button. From there, it can calculate flight plans, fly around obstacles, and check in with ground controllers when it spots something interesting, like smoke or troop movement. At the end of the mission, it flies home and lands itself. Mantis’s maiden flight went off without a hitch in Australia last October, an astoundingly fast development—it didn’t even exist in 2007. BAE Systems expects it to be ready for sale within two years and hopes to use it as a proving ground for systems in its forthcoming automated stealth bomber, the Taranis.

Notable Feature: Mantis is the first in a new breed of smart drones. A craft that can hone its searches requires less bandwidth than those that constantly stream images. Mantis can also monitor itself for damage—a sputtering engine, for example—and adjust its electronics to complete a mission. It can fly up to 345 miles an hour and operate for up to 36 hours.

Samarai UAV

Samarai UAV from Lockheed Martin

Samarai UAV

Class:
Biomimetic

Size:
150 grams, 12-inch wingspan

Habitat:
Lockheed Martin’s Advanced Tech Laboratories in Bethesda, Maryland

Behavior:
Like the spiraling maple-leaf seedlings—more commonly known as whirlybirds—that inspired it, the single wing spins around a central hub to create lift. A miniature jet engine provides thrust. A tiny flap on the trailing edge of the wing, its only moving part, controls direction. If engineers can shrink it to three inches and 15 grams, the autonomous device could be used to spy indoors.

Notable Feature: In the future, a camera mounted on the central hub that snaps a picture once every rotation will collect enough images to stitch together full-motion video. Diet: Today, batteries; but engineers plan to feed the next version propane, which is light and readily available in the military supply chain.
