what does speed have to do with sound and if there's no wall in the sky out exactly do you break a sound barrier hey guys Amy here with you on the news today talking speed passing not. most of us will probably never go supersonic though the idea of cutting travel times and 1/2 it's so appealing it's not something it's likely to become commonplace anytime soon but let's start with a bit of a history lesson in the 1880s Austrian physicist Ernst Mach was studying the supersonic flow of app is using a shadowgraph company successfully photographed a bullet traveling faster than the speed of sound what is images showed with a bullet with a shock wave in front of it and another one trailing behind it a clear proof of the phenomenon of compressibility This research eventually led to the measurement that bears his name amaka number is the ratio of the speed of an object traveling through gas to the speed of sound in that Gap because well we don't think about it air is made up of molecules and like any other physical substance those are molecules can compress and when they compress they form Shockwave it stay strong make flying faster than the speed of sound such a challenge and in the 1940s Howitzer coming face-to-face with the challenge these shock waves vibrate the air molecules are made up and windows are molecules vibrate they vibrate whatever is compressing in the case of fast flying airplanes the Shockwave cancer can airplanes hard enough to rip it apart it was clear to engineer's in the 1940s that the future of Aviation lazy on the sound barrier so someone would have to build an airplane solid enough and fast enough to break through that wall it was the Bell aircraft Corporation working on a contract with the US Army Air Force survive the solution taking design inspiration from a bullet Bell engineering signs the excellent aircraft specifically to break through that wall compressed air in the sky the Advent of SuperSonic flight opened a whole new era of Aviation and the fire Mach numbers don't come with the same barriers everything and speed is nonetheless a major technological turtle on record was set in 1967 when the NASA Air Force F-16 a rocket-powered art of an aircraft hit a top speed of Mach 6.7 what is at 4519 miles per hour exit team what does a Hypersonic vehicle most fighter jets today aren't nearly that fast so there are supersonic Fighters Air Force plane like the F15 Eagle and the F-22 Raptor are both supersonic fighter jets and the F-22 can even hit Mach 2 using afterburners but there's another challenge busy with supersonic flight and that's a sonic boom sonic boom is the sound an airplane makes when it smashes through that wall compressed are the builds up in front of it but the boom doesn't just come when the plane goes supersonic it keeps going in the wake of that supersonic aircraft this is exactly why the conquered the world only supersonic passenger plane that flew from 1976 to 2003 only ever flew over ocean in fact the Federal Aviation Administration prohibited domestic civil supersonic flights over land in 1973 but all is not lost NASA is Aviation Park are looking into identify an acceptable loudness level and working on so-called low boom aircraft design that would reduce tonaquint levels and maybe bring back supersonic passenger flights but that's still something to look forward to down the line and the US Air Force always has eye on the Future 2 and it's a big swervy news the United States Air Force is Howard by Airmen and fueled by Innovation everyday American Airman go above and beyond race barriers with professionally and personally what is overcoming poverty to become a nurse in officer or becoming the first female Thunderbird pilot these are men or no doing what was once thought to be impossible have any of you blowing supersonic late if so it's help what it was like in the comments below because I'm dying to know what it's like and if you haven't do you want to let us know and don't forget to subscribe for more Deanie's every day of the week
