Supersonic Passenger Travel May Be Coming Closer To Reality
2014-06-18 03:31:45

Karen Northon, NASA The return of supersonic passenger travel may be coming closer to reality thanks to NASA’s efforts to define a new standard for low sonic booms. Several NASA aeronautics researchers will present their work in Atlanta this week at Aviation 2014, an annual event of the American Institute of Aeronautics and Astronautics. They will share with the global aviation community the progress they are making in overcoming some of the biggest hurdles to supersonic passenger...

Sonic booms usually mean something cool. The space shuttle is coming in for a landing or a jet fighter is flying overhead. We don't hear them very often, so when we do it's an event. But imagine if aircraft manufacturers designed and built a vehicle that carried passengers or cargo at supersonic speeds over land. Sonic booms would be happening all the time; and they're loud and annoying. That's why the Concorde flew over the ocean. Noise regulations in most countries wouldn't allow it to fly...

The U.S. space agency says it has conducted a series of flight tests that might help produce quieter supersonic aircraft. The National Aeronautics and Space Administration said the tests measured shock waves generated by an F-15 jet to validate computer models that could be used in designing commercial aircraft that can fly faster than the speed of sound without generating loud sonic booms over land. Supersonic flights over land generally are prohibited because of such loud noises. A sonic...

NASA is concluding a series of flight tests to measure shock waves generated by an F-15 jet in an effort to validate computer models that could be used in designing quieter supersonic aircraft. The Lift and Nozzle Change Effects on Tail Shock, or Lancets, project embodies research aimed at enabling the development of commercial aircraft that can fly faster than the speed of sound without generating annoying sonic booms over land. Supersonic flight over land generally is prohibited because of...

Early fighter pilots were sometimes called knights of the air, a reflection of medieval times when knights used blunted lances in jousting tournaments to dismount competitors from their horses. Now, jet-borne jousting is combating supersonic shockwaves, hopefully enough to lessen the resulting sonic boom heard on the ground. Gulfstream Aerospace and NASA's Dryden Flight Research Center have teamed in a project called Quiet Spike to investigate the suppression of sonic booms. The project...


Word of the Day
humgruffin
  • A terrible or repulsive person.
Regarding the etymology of 'humgruffin,' the OED says (rather unhelpfully) that it's a 'made-up word.' We might guess that 'hum' comes from 'humbug' or possibly 'hum' meaning 'a disagreeable smell,' while 'gruffin' could be a combination of 'gruff' and 'griffin.'
