Jet Fighter Breaking The Sound Barrier Sonic Boom

[yeebrodo14]

Well why did it make a sonic boom.........

[geoago]

However, it was close, close to the sound. In fact, go up immediately to lose speed ....

[avaruuskojootti]

speed of sound aproximately 1300km/h, top speed of fighter jets (1.5-3 mach) about 2 mach (NATO's Fighter jets top speed) = 2036km/h aproximately and i bet this fighter jet went over 1300km/h, so doesnt that count as breaking the sound barrier? lol, sorry for my english if i typed anything wrong iam from finland. :P

[popsnacks2]

didnt break it its against national law to break the sound barrier over land unless in war time,

[TurbineProductionsX]

it didnt break it... you could hear the sound before it arrived..

[falconwings]

I highly doubt that a Mirage F1 can go super at sea level. Not enough mojo.

[metaljamzander]

hahah thats funny cuz when you hear the boom the camera man looks like h shat himself  X D

[sussexj]

there was a little boom there. Might have hit mach for a second

[eloidor]

mach numbers are different depending on altitude, humidity temperature and atmospheric pressure . @ sea level with a temperature of 45*f the speed of sound is 762Mph @ over 32,000-65000 feet where the temperature is -65*f the speed of sound is 660 Mph so the conditions have to be just right and for this shot they all were

[chadoreo]

Boring

[Eflightheli]

that's not a shock wave. It's actually vapor, which is when the jet is moving so fast or if it is preforming such a tight manuver that it squeezes the water vapor out of the air. Alot of people confuse that.

[PaladinHludwig]

Its called a Mirage because you could never lock on to a supersonic target!

[kleidoscope]

nope breaking the sound barrier is illegal, he might have pushed beyond .90-.95 to hit a sonic boom, if it was 1.0 or 1.2 Mach, ya then the sound barrier would have been broken..

[c4bmx22]

Was not the sound barrier, but it was still cool.

[LegoFreakFarter]

@c4bmx22 Yeah it was, twonk.

[c4bmx22]

@LegoFreakFarter Was not breaking the sound barrier..

[LegoFreakFarter]

@c4bmx22 yeah it was

[c4bmx22]

@LegoFreakFarter Dude, it was not.. do you not know anything about jets?? I work with them every day... It was not a sonic boom (breaking the sound barrier) they were to low and the people near it would have had very very bad headaches if not damage to their ears if it was a sonic boom.. countries have limits on what can be done.. such as breaking the sound barrier below a certain elevation.

[LegoFreakFarter]

@c4bmx22 Yeah sure. You work with them every day... And you have BMX in your username.... Somehow I doubt that.

[c4bmx22]

@LegoFreakFarter Lol. and you know everything about planes because you have Lego.. and freak and farter in your name.. First of all, I'm in the USAF and I used to ride BMX for a living from when I was in middle school till I was 21.. I'm an Aerial Gunner and I work near and around fighter jets daily.. before I was an Aerial Gunner, I used to work on jets. such as the F-15

[1412ronnie]

@c4bmx22 you fucked up you said you used to ride bmx for a living but then after that you said befor you becom a aerial gunner you worked on jets suck as the f-15 make you mind up :)

[c4bmx22]

@1412ronnie I used to ride BMX professionally.. If you would read the other comments, you would noticed the words used and to.... Also, being a jet engine mech and having switched your job is possible.

[skittlepower95]

@LegoFreakFarter it never broke the sound barriew u could hear it coming before it passed the camera if it broke the sound barrier it would be silent until it passed the camera

[N94AWR]

@skittlepower95 sorry but there is a problem with your theory. that should be the case but the plane does experience the trasonic vapor effect.

[skittlepower95]

@N94AWR ok some of the air passing over the plane is supersonic, but the plane itself is not.

[Saighton]

@skittlepower95 it went close at 0:04, you can see the shock wave begin to form on the leading edge of the tail I think.

[skittlepower95]

@Saighton probably a water vapour

[crossessolonely]

@Saighton I don't think that's the sound barrier, the plane is pulling up and appears to be pulling high enough G for adiabatic cooling to take place- creating visible moisture.

[josetomaslf]

@Saighton thats, i dont know whats it called, but the thing is it happens often. it didnt break the sound barrier, its like @skittlepower95 said, you could hear it coming!!! breaking the sound barrier means faster than sound, sound is behind the plane!! pretty cool though!!

[RampantRedBull]

@Saighton Probably not, thats just vapor being created from the wings.

[nexus1g]

@RampantRedBull That's a vapor cone produced as predicted by the Prandtl-Glauert singularity. It occurs in transonic (air is still moving at supersonic speeds around the aircraft) and supersonic flight.

[RampantRedBull]

@nexus1g But this doesn't mean that its actually breaking the sound barrier.

For example, im sure you will agree with me that the C17 Globemaster is not capable of supersonic flight.

Yet in this picture a similar effect is created: wwwDOTrafDOTmodDOTukSLASHdownl­oadsSLASHwallpapersSLASHc17SLA­SHc17_03_1280.jpg

[nexus1g]

@RampantRedBull The image you linked is not an effect demonstrating the Prandtl-Glauert singularity. It's similar in that they both have the visible outcome of vapor, but it is not related to the Prandtl-Glauert singularity which has to do with the compression of a sock wave to near infinite pressure and looks completely different from condensation due to vortices.

[RampantRedBull]

@nexus1g Well could this be what is happening in this video, rather than the sound barrier being broken.

[nexus1g]

@RampantRedBull It could not be that. The reason is because the vapor cone was surrounding the plane. Vortex-based vapors appear in very specific places where the aerodynamics create said vortices.

Here's an exaggerated view of the Prandtl-Glauert singularity making itself visible via the vapor cone: watch?v=6iawZ-TzFoo -- Keep in mind the size of this vapor cone is significantly larger than typical.

[umpalumpa101909]

@Saighton THat's not a shock wave, it's condensation

[F16AirPower]

@skittlepower95 I definitly hear a boom... Maybe there were other jets flying around and you could hear them flying... But around 0:09 when climbs and passes the camera I hear a boom!

[skittlepower95]

@F16AirPower there is a slight boom but you could hear the jet coming way before it.

i doubt it was from other jets

[locomotiveAlex1996]

@skittlepower95 thats because it hadnt broke it yet, if you had a concept of sound then the sonic boom wouldnt have been in the shot if the plane was already going faster than sound

[skittlepower95]

@locomotiveAlex1996 i know it hadnt broken it yet........thats what im arguing for

[morganou79]

very good !!!
