coondoggie writes "As the military and occasionally commercial aviation researchers look to fly aircraft higher, farther and faster — much faster, sonic booms such planes can create can cause problems on the ground.
That's why NASA and the Japan Aerospace Exploration Agency (JAXA) this week announced a partnership to jointly research sonic boom. NASA said sonic boom modeling is one of the key technologies needed to let a next generation supersonic aircraft quiet enough that it can fly supersonically over land without significant disturbance to the people or damage to property under such noise.
The sonic boom work will include a look at what JAXA has done with its "Silent Supersonic Technology Demonstration Program" that is researching key technologies to realize a silent supersonic transport. JAXA's program looks at all manner of flight technologies — such as aircraft body and wing composition as well as wing design to reduce sonic booms. Because of sonic boom intensity, the Federal Aviation Administration prohibits supersonic flight over land, except in special military flight corridors.
