NASA Dryden F/A-18 Will Be Chasing 'FaINT' Sonic Booms
2012-10-26 09:22:14

NASA´s Supersonics Project will embark on its latest effort to soften sonic booms when a NASA F/A-18 aircraft takes to the air in a project called Farfield Investigation of No Boom Threshold, or FaINT, beginning in late October. As the latest in a continuing progression of NASA supersonics research projects aimed at reducing or mitigating the effect of sonic booms, FaINT is designed to enable engineers to better understand evanescent waves, an acoustic phenomenon that occurs at the...

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...

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
cruet
  • A vial or small glass bottle, especially one for holding vinegar, oil, etc.; a caster for liquids.
This word is Middle English in origin, and ultimately comes from the Old French, diminutive of 'crue,' flask.
