Bravo Delta Airbus A380-800 Virgin Livery




Better display model of the new A380-800 Airbus. Well up to Bravo Delta's normal high standard and finish this is another good size model, measuring 17" in length and with a 18" wingspan. A long lasting and sturdy model excellent for the desk top.


Calm excitement filled the ground control station. Engineers stared intently at their computer screens as the pilot, sitting next to them, flexed his fingers on the controls. Ground crew tending the aircraft finished putting away their equipment. Preparations for the first flight of the unmanned X-48B Blended Wing Body research aircraft were complete. Years of research, design, construction, wind tunnel and ground tests coalesced into this one moment of time.Radios crackled. "Tower, Skyray 48 in position, lakebed runway 23, request clearance for takeoff...""Skyray 48 roger, main base winds 220 at 6, report airborne, lakebed 23...""Wilco""Five, four, three, two, one, brakes..."Quickly, the manta ray-shaped aircraft rolled down the dry lakebed runway trailing a plume of dust as it picked up speed, its three small jet engines whining.With an excitement that only comes with an aircraft's first flight, the triangular red, white and blue X-48B leapt into the air, obviously wanting to fly."Skyray 48's airborne," Boeing pilot Norm Howell called, matter-of-factly. And with that, years of toil blossomed into the sweet fruit of success on July 20, 2007 at NASA's Dryden Flight Research Center on Edwards AFB, Calif.One of the latest cutting-edge experimental aircraft, or X-Planes, the X-48B BWB is a collaborative effort of the Boeing Co., NASA's Fundamental Aeronautics Program, and the Air Force Research Laboratory. The 21-foot wingspan, 500-pound, remotely piloted plane is designed to demonstrate the viability of the blended wing shape. And demonstrate it has.After completion of six flights, the X-48B team began a four-week maintenance and modification period during which removable leading edges with extended slats are being replaced with slatless leading edges in order to mimic a slats-retracted configuration. The change requires a software update to the flight control software. In addition, the team is removing and replacing all of the aircraft's flight control actuators for maintenance purposes.NASA is interested in the potential benefits of the aircraft - increased volume for carrying capacity, efficient aerodynamics for reduced fuel burn, and, possibly, significant reductions in noise due to propulsion integration options. In these initial flights, the principal focus is to validate prior research on the aerodynamic performance and controllability of the shape, including comparisons of flight test data with the extensive database gathered in the wind tunnels at NASA's Langley Research Center in Virginia. The Subsonic Fixed-Wing Project, part of NASA's Fundamental Aeronautics Program, has long supported the development of the blended wing body concept. It has participated in numerous collaborations with Boeing, as well as several wind tunnel tests for different speed regimes. The team is focused on researching the low-speed characteristics of the design and expanding its flight envelope beyond the limits of current capabilities.In addition to hosting the X-48B flight test and research activities, NASA Dryden is providing engineering and technical support -- expertise garnered from years of operating cutting-edge air vehicles. NASA assists with the hardware and software validation and verification process, the integration and testing of the aircraft systems, and the pilot's ground control station. NASA's range group provides critical telemetry and command and control communications during the flight, while the flight operations group provides a T-34 chase aircraft and essential flight scheduling. Photo and video support complete the effort.The composite-skinned, 8.5 percent scale vehicle can to fly up to 10,000 feet and 120 knots in its low-speed configuration. The aircraft is flown remotely from a ground control station by a pilot using conventional aircraft controls and instrumentation, while looking at a monitor fed by a forward-looking camera on the aircraft.

Guinness World Records has recognized the world speed record set by NASA's hypersonic X-43A aircraft earlier this year in an experimental flight over the Pacific Ocean. Using a scramjet engine, the unpiloted, 12 foot-long aircraft achieved Mach 6.83 -- almost seven times the speed of sound -- or nearly 5,000 mph, in a March 27 flight.The accomplishment will be included in the 2006 Guinness World Records book, set for release this time next year, as follows:"On 27 March 2004, NASA's unmanned Hyper-X (X-43A) airplane reached Mach 6.83, almost seven times the speed of sound. The X-43A was boosted to an altitude of 29,000 m (95,000 ft) by a Pegasus rocket launched from beneath a B52-B aircraft. The revolutionary 'scramjet' aircraft then burned its engine for around 11 seconds during flight over the Pacific Ocean."If NASA researchers have their way, the record won't stand long. The final flight in the Hyper-X program is scheduled to take place in October, when another X-43A aircraft will attempt to fly at Mach 10 -- ten times the speed of sound -- or 7,200 mph.The March 27 flight was part of NASA's Hyper-X program, designed to demonstrate advanced high-speed propulsion system concepts to overcome one of the greatest aeronautical research challenges -- air-breathing hypersonic flight. The advantage of air-breathing flight is that the vehicle, whether it is aircraft or spacecraft, scoops the air its engines need from the atmosphere rather than carrying heavy, bulky tanks, as rockets do.The challenge is to introduce fuel, ignite it and produce positive thrust while highly compressed air rushes through the engine in mere milliseconds -- roughly analogous to lighting a match and keeping it burning in a hurricane-force wind.Compared to rocket-powered vehicles like the Space Shuttle, scramjets promise more airplane-like operations for increased affordability, flexibility and safety in ultra high-speed flights within the atmosphere and into Earth orbit.The X-43A flight easily set a world speed record for an air-breathing engine aircraft. The previous known record was held by a ramjet-powered missile, which achieved slightly more than Mach 5. A ramjet operates by subsonic combustion of fuel in a stream of air compressed by the forward speed of the aircraft itself, as opposed to a normal jet engine, in which the compressor section (the fan blades) compresses the air. A scramjet (supersonic-combustion ramjet) is a ramjet engine in which the airflow through the whole engine remains supersonic.The highest speed attained by a rocket-powered airplane, NASA's X-15 aircraft, was Mach 6.7. The fastest air-breathing, manned vehicle, the SR-71, achieved slightly more than Mach 3. The X-43A more than doubled the top speed of the jet-powered SR-71.Guinness World Records' science editor David Hawksett has already expressed an interest in attending the fall flight."Operating an atmospheric vehicle at almost Mach 7 is impressive enough, but to be able to use oxygen from the air, instead of a fuel tank, as it screams into the engine intakes at 5,000 mph is a mind-boggling technical achievement. It's wonderful to see scramjet technology finally begin to take off," said Hawksett.The Hyper-X program is conducted by NASA's Aeronautics Research Mission Directorate with the NASA Langley Research Center, Hampton, Va., as lead center with responsibility for hypersonic technology development and the NASA Dryden Flight Research Center, Edwards, Calif., responsible for flight research and testing.




2010 Toyota Camry

The unexpected reveal of the 2010 Toyota Camry and 2010 Toyota Camry Hybrid at the Detroit Auto Show has left many of us speechless. Speechless as in, we weren't really that surprised to see the next version of the number one selling car in America. The 2010 Camry is expected to go on sale in March.

2008 Lamborghini Gallardo
The 2008 Gallardo is a 2-door, 2-passenger luxury sports car, or convertible sports car, available in 3 trims,..


Adrenaline describes the Murtaya as an everyday supercar, and it certainly lives up to that tagline, thanks to 911 GT3-humbling pace combined with decent practicality and reliable Subaru underpinnings. There are few cars which can match its all round capability and even fewer at the same sort of price.The Murtaya demonstrator, based on a near-standard Impreza WRX, has been officially timed at 3.5 seconds to 60mph. From a standstill it will hit 100mph in 7.5 seconds (around the same time as a Koenigsegg CXX) and top speed ranges from 145mph to well over 170 depending on the gearing.PerformanceSo it's fast, but what's truly addictive is the way in which that performance is delivered. Initially it seems modest, a little tame even, but then suddenly the turbo reaches full boost and the Murtaya is catapulted down the road at a ferociously rapid pace.One AMS customer also has a tuned Porsche 911 GT3 and claims the Murtaya is faster. It's not hard to believe. The abrupt delivery takes some getting used to. You have to be wary of accelerating mid-corner, but once you learn to work with it, the turbocharged rush becomes highly addictive.
