The sonic boom problem - Katerina Kaouri

View full lesson: ed.ted.com/lessons/what-causes...
Objects that fly faster than the speed of sound (like really fast planes) create a shock wave accompanied by a thunder-like noise: the sonic boom. These epic sounds can cause distress to people and animals and even damage nearby buildings. Katerina Kaouri details how scientists use math to predict sonic booms' paths in the atmosphere, where they will land, and how loud they will be.
Lesson by Katerina Kaouri, animation by Anton Bogaty.

Technically, Chuck Yegar was the first person to break the Sound Barrier and lived to tell about it. During WW II fighter pilots during a power dive would sometimes break the sound barrier, but their plane would tear apart from the over pressures on the control surfaces thus crashing the plane & killing the pilots

[@mrrolandlawrence]

proved to be untrue. the 1st person to break the sound barrier was george welch in the xp-86 a few days before chuck. the bell x1 record was amended to say "break the sound barrier in level flight. the xp-86 was pretty much i a vertical dive to get there.

[@Thx1138sober]

There used to be sonic booms all the time. Back in when I was age 4, 5 and 6 years old we would hear sonic booms almost every day and sometimes several of them a day. They would rattle all the windows and shake the whole house. It wasn't just where I lived in Kentucky because I also heard them at my grandparent's house in Clearwater FL. About 1964 or 65 they made the Air Force quite flying supersonic over most of the USA.

[@khangb3]

So if I had a plane that could move faster than sound and have infinite fuel, I could keep flying around the earth without ever hearing the sound that I would be running away from?

[@WGFinc]

In short: Supersonic planes were too op because you could go too fast and damage your opponents at the same time so the devs banned them. However, that caused many supersonic plane enthusiasts to quit the game so the devs unbanned them over sea.

[@jonathanwang7456]

Yay! We did it! Soon we have to deal with the “light barrier” problem.

[@LostinSongs]

Not really. Light travels about a million times faster than sound - it is already hard for humans to build aeroplanes to surpass the sound speed - I cannot imagine how they could possibly create 1 million times faster aeroplanes, at least with the current technology.

[@Proletrolliat]

@@LostinSongs it is possible to move at 4% speed of light with current tech though as far as i know

[@randensim3295]

Lukson sonic booms are from going >speed of sound. So there won’t be a problem with light barrier and booms since you can’t go past light speed

[@ilickcatnip]

Nice dream. But currently the topmost speed recorded by a human made object is of Parker Solar probe, but that was temporary, only due to sun's gravitational attraction. True holder of the record, According to be must be the Helio-B orbitor, which could attain only 0.0233% of the speed of light! So forget your dream. Plus Einstein's Special and General relativity puts speed of light as the fundamental barrier of speed in this universe that can never be matched by things having mass, forget about passing it, you can't even get there....

SEARCH UP BULLET SHRIMP

[@taofledermaus]

Cool video! We have seen some of the lighter objects we have shot at supersonic speeds, actually get pushed out of their trajectories by their own shock waves as they passed near larger, stationary objects. Anyone know the term for that?

[@neandercatz8877]

***** I found you, Where is my cookie?

[@taofledermaus]

Neandercatz I was starting to think my comment was invisible. lol Damn channels that don't read their comments... I tell you.

[@neandercatz8877]

True!

[@LostinSongs]

***** My (scientific) guess is: because the shock waves that the lighter objects create get reflected by the larger, stationary objects which then causes the lighter objects to be pushed out of their trajectory.

[@stinkyfungus]

+TAOFLEDERMAUS huh... you are the last guy I would have thought I'd randomly run into looking for sonic boom vids. answering your question sort of... its common for long range shooters to have a bullet loose stability (and loss of accuracy) as it slows down from supersonic to transsonic speed, has something to do with the bullet being upset by its own shockwave as the shockwave catches up to it. not sure what the proper terminology is for that... but its a thing. seems to me that if a projectile can be upset by its own shockwave, that the shockwave when distorted/compressed could upset the bullet as well, like your freakazoid slug. I also think a lack of stabilizing spin came into play... since I've shot at game near heavy brush and never had a bullet deflect like that.

the stabiliser, an all moving tail, is crucial part of a transonic or Super sonic design, however, the US stole it from the UK and hastened the launch of the X-1

[@acassiopeia6439]

Not quite right, we gave them our research data from the Miles M.52 and design drawings, including the flying tail, in exchange for their research data. But the U.S. never held up their end of the deal and gave us nothing in return, then the British government cancelled the M.52 program. The bastards.

[@reggiep75]

The US first shafted allies involved in the Manhattan Project by cutting them out with the Atomic Energy Act of 1946, where they took all of the scientific input from the other developing nations (UK and Canada) opted to not develop further with allies and said f**k off! They then did it AGAIN in 1946-1947 with the Miles M.52 and Bell X-1 research and data exchange and shafted us over by withholding everything they had and pawed over everything we gave them. And finally after that, the UK government pulled the plug which was declared the third blow. Needless to say, we realised the US couldn't be trusted for a long time after that until there was a little thawing in relations.
