WHAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAT Mach 10 is in the region of 11,000km/h or 6,800mph for the altitude at which the X-43A was being flown (33km or 111,000ft). The vehicle performed "flawlessly". news.bbc.co.uk Superfast Nasa jet pushes Mach 10 Nasa has flown an unmanned experimental jet to a speed that preliminary data suggested was just short of 10 times the speed of sound - a record. The X-43A - a supersonic combustion ramjet (scramjet) - made the run over a naval test range in the Pacific Ocean. The 3.7m-long vehicle had already set a world best for an "air breathing" jet of Mach 6.83 - nearly seven times the speed of sound - on a flight in March. The latest feat is the culmination of decades of work by many researchers. Mach 10 is in the region of 11,000km/h or 6,800mph for the altitude at which the X-43A was being flown (33km or 111,000ft). The vehicle performed "flawlessly". See the X-43A scramjet vehicle in detail "It was about Mach 9.6," said engineer Randy Vorland after Tuesday's flight. "We performed pretty much like we expected. He added: "I think it's easier than people think it is. We can really do this stuff. I don't mean to make it sound too easy, but it's definitely doable." Wing trip Scramjets are being developed in a number of countries as an alternative propulsion system to rockets. Future applications could include hypersonic missiles and aeroplanes, and reusable single- or two-stage-to-orbit space launchers. Subsonic engines have rotating parts to compress air Scramjets burn hydrogen fuel in a supersonic air stream Air is compressed by fast forward movement of vehicle Rapid expansion of hot air out of exhaust produces thrust Some commentators have even speculated that scramjets could one day be used on passenger airliners, dramatically cutting long-haul journey times. "Absolutely, we're just going to have to wait a while," said Joel Sitz, the X-43A project manager. "It took a long time from the Wright brothers to the first flight across the ocean. It might take the same amount of time before this technology can be applied to commercial aircraft, but I think some day it will be there." Tuesday's flight went ahead as planned over the Naval Air Warfare Center Weapons Division Sea Range, which is just to the northwest of Los Angeles. The X-43A was positioned on the nose of a Pegasus booster rocket and attached to the underside of a B-52B aircraft's wing. The paired X-43A and booster were then lifted to an altitude of 12km (40,000ft) and released; the booster taking the scramjet higher and faster. Separation and onward flight of the scramjet occurred at an altitude of about 33.5km (111,000ft). The telemetry showed the X-43A was set free by the booster at a speed well in excess of Mach 9 but was able to maintain its cruising velocity under the thrust from its scramjet. Engineers followed the X-43A as it travelled more than 1,000km (620 miles), eventually losing speed and plunging into the Pacific. Fast flowing The advantage of scramjets becomes apparent once they have been accelerated beyond about Mach 4. They are able to burn their fuel - in this case hydrogen - without the need to carry heavy tanks of oxidiser, as rockets must. Instead, they scoop their oxygen from the air, which is naturally compressed by the forward speed of the vehicle and the shape of its inlet. A booster rocket lifted the X-43A high into the sky Conventional jet engines have rotating blades to compress the air; scramjets have no such moving parts. The fuel is ignited in a supersonic air stream - a technical challenge that has been likened to "striking a match in a hurricane". Successful combustion relies on critical control of temperature and pressure within the engine. The concept should allow for greater payload capacity at reduced cost - and finer control over a vehicle. Unlike rockets which tend to produce full thrust or nearly full thrust all the time, scramjets can be throttled back and flown more like an aeroplane. This makes them potentially safer. Future funds Tuesday's flight was the third and final mission for the Nasa vehicle, which came out of the agency's Hyper-X programme. It is not clear where the technology fits into Nasa's future plans. A proposal to develop a larger hypersonic vehicle - the X-43C - was scrapped following President Bush's announcement in January that America would revive manned missions to the Moon by 2015 and attempt an expedition to Mars. All effort is now directed at finding a suitable replacement for the space shuttle, and this is to be based on conventional rocket technology. Nasa will be reluctant, however, to give up the gains - and the successes - of the X-43A. "We'll work our way through what we think we have learnt and see what our next step might be, and talk about some foundational technologies we might want to do," said Dr Vic Lebacqz, the head of aeronautics at Nasa, after Tuesday's flight. For Joel Sitz, the vision is develop vehicles that can take off from a standing start and switch to different propulsion systems as they go faster and faster. "The next step I would like to see at Nasa is to take a turbine engine and a ram-scram-jet, combine those propulsions cycles, put some hardware together and start testing it. "Maybe in a couple of years we could then put the budget together to put an aeroplane around that technology." Outside Nasa, a group at the University of Queensland in Australia plans to conduct two Mach 8 flights and a Mach 10 flight in September 2005. The Queensland team will test three separate scramjet configurations designed by the UK's QinetiQ company, the US Defense Advanced Research Projects Agency (Darpa) and the Japanese Aerospace Exploration Agency (Jaxa). The US Air Force has a programme called HyTech, which is aimed at developing a hypersonic cruise missile.

,,,,,,,WBSK .0052 Round 2 (NEWS) WebSky, Inc. and Argentinean Partner to Launch Initial Project in Buenos Aires Province This Month Wednesday February 2, 9:01 am ET SAN FRANCISCO--(BUSINESS WIRE)--Feb. 2, 2005--WebSky, Inc. (Pink Sheets:WBSK - News) announced today that its joint venture wireless broadband project in the Province of Buenos Aires, Argentina will begin revenue operations prior to the end of February, 2005. The necessary agreements and orders to assure that launch are being executed today in San Francisco and Buenos Aires. Under the terms of the frequency license agreement of its Argentine partner, commencement of revenue service is required to occur before March 5, 2005, and with today's announcement WebSky and its local partner confirm that the required time frame for deployment will be met. Initially, wireless, broadband, non-line-of-sight services will be offered to business and residential customers in the city of La Plata, the capital of the Province of Buenos Aires, some 35 miles southeast of downtown Buenos Aires. Shortly after the launch of the initial service in La Plata, it will be expanded to cover all of that city using the most advanced wireless systems currently available. Thereafter, the joint venture will, over the next twenty-four months, expand its service area to cover the entire Province of Buenos Aires and beyond, covering more than 16 million people and the vast majority of Argentina's business, government, and educational sectors. La Plata is a significant and an attractive market for wireless broadband service in its own right. It is the fifth largest metropolitan area in Argentina, with a population in excess of 675,000. The site of a major university and the nation's principal port and duty free zone, La Plata also has a large number of provincial governmental offices and is a prosperous, progressive, and modern city. The joint venture selected La Plata as the site of its initial operations because the city fit all the criteria WebSky has set up for its international expansion including: (1) it is a market underserved by pre-existing broadband providers, (2) the basic infrastructure to allow connectivity to the internet backbone is already in existence, and (3) there is significant pent up demand for broadband services together with positive demographics. As in all emerging markets in which WebSky is developing wireless broadband projects, Argentina's relatively underdeveloped wireline telecommunications system leaves the country with no other alternative for deploying a high speed broadband network than next generation wireless systems. "We are very pleased to be able to confirm that the joint venture will be launching its initial operations in La Plata on schedule, later this month," noted Douglas Haffer, President and Chief Executive Officer of WebSky. "The potential for WebSky in the greater Buenos Aires market is enormous and it is appropriate that this market will be the first one commercially launched by WebSky," he concluded. As previously reported, WebSky expects that within three years, and based upon current schedules for construction and deployment, annual revenue for the Buenos Aires market alone will exceed $US40 million. About WebSky, Inc. WebSky, Inc. is a San Francisco based company that currently controls licensed radio frequencies in the MMDS-band -- 2.5GHz to 2.7GHz -- in seven small and medium sized cities in the United States in Key West, Florida; Ukiah, California; La Crosse, Wisconsin; Grand Rapids, Michigan; Hilo, Hawaii; Aspen, Colorado; and Vail Colorado. The Company will be constructing high speed, wireless broadband Internet systems. In addition, WebSky has entered into agreements with local telecommunications companies in India, Thailand, and Indonesia, to developed wireless broadband systems in those countries.
