NASA's primary installation for flight research. NASA receives official recognition from Guinness World Records. NASA's third and last X-43A hypersonic scramjet research vehicle took to the skies today for a captive-carry flight. NASA Researcher Involved in X-43A Flight Program Since its Beginning NASA Dryden's Laurie Marshall explores hypersonic flight. NASA's Hyper-X Program is ready for its greatest challenge - flying the "scramjet"-powered X-43A at nearly 10 times the speed of sound.Įnthusiasm for flight propels researcher's interest in X-43A X-43A Scramjet Readied for Mach 10 Flight NASA's X-43A Scramjet Breaks Speed Record Getting Ready for Mach 10: 3.2 Mb | 6 Mb | 8.9 Mb | 14.5 Mb The X-43A more than doubled, then tripled, the top speed of the jet-powered SR-71. Air Force SR-71, achieved slightly more than Mach 3.2. The fastest air-breathing, manned vehicle, the U.S. In March 2004, the X-43A set the previous record of Mach 6.8 (nearly 5,000 mph). The X-43A set the new mark and broke its own world record on its third and final flight on Nov. Guinness World Records recognized NASA's X-43A scramjet with a new world speed record for a jet-powered aircraft - Mach 9.6, or nearly 7,000 mph. Pegasus booster rocket ignites to send the X-43A on its record setting flight on Nov. + NASA Home > Missions > Research Aircraft An airplane flying less than Mach 1 is traveling at subsonic speeds, faster than Mach 1 would be supersonic speeds and Mach 2 would be twice the speed of sound. Mach 1 is the speed of sound, which is approximately 760 miles per hour at sea level. "Mach Number" was named after the Austrian physicist Ernst Mach. The next developmental flight of this system is scheduled for no earlier than February 21, 2004.The site requires that JavaScripts be enabled in your browser. and Dryden Flight Research Center in Edwards, Calif. The Hyper-X program is a joint project between the Langley Research Center in Hampton, Va. The vehicle will be tested at speeds up to Mach 10. The first test flight of the X-43A, which took place on June 2, 2001, failed due to a stabilization problem with the booster rocket's directional fins.Īn artist's conception of the X-43A in flight. The Pegasus is dropped by a B-52 aircraft and launched to an altitude of over 90,000 feet, where the X-43A is released and flown under its own power.Įach of the three vehicles appear identical but have slightly different oxygen intake designs, based on what speed their test flights are planned to accomplish. The company fabricated three X-43A aircraft for NASA, to be flown aboard modified Pegasus rockets developed by the Orbital Sciences Corporation. The X-43A, a 12-foot long scramjet-powered research vehicle, was constructed by MicroCraft, Inc., now known as Alliant Techsystems, Inc. NASA's Hyper-X program is working to develop scramjets into a practical technology. On August 16, 2002, the University of Queensland in Australia completed the first successful flight of a scramjet vehicle, reaching speeds of Mach 7, or seven times the speed of sound. An 18-hour trip to Tokyo from New York City becomes a 2-hour flight.Ī look at one of NASA's developmental scramjets, the X-43A, undergoing ground testing. How fast? Researchers predict scramjet speeds could reach 15 times the speed of sound. The craft becomes smaller, lighter and faster. That's the idea behind a different propulsion system called "scramjet," or Supersonic Combustion Ramjet: The oxygen needed by the engine to combust is taken from the atmosphere passing through the vehicle, instead of from a tank onboard. Onetime trans-Atlantic fliers, for short. We have 1 possible solution for this clue in our database. Finally, we will solve this crossword puzzle clue and get the correct word.

First of all, we will look for a few extra hints for this entry: Speed-of-sound jets. Take away the need for liquid oxygen and your spacecraft can be smaller or carry more payload. Let's find possible answers to 'Speed-of-sound jets' crossword clue. Why? Rockets combine a liquid fuel with liquid oxygen to create thrust. One thing has always been true about rockets: The farther and faster you want to go, the bigger your rocket needs to be.
