What does it mean exactly when a jet breaks the sound barrier?

Author: admin Category: 5

Also, what is that water vapor ring that forms around the jet when it does break?
breaking the sound barrier is when the vehicle exceeds the speed at which sound travels. The cone of vapor you see is the existing moisture in the air being condensed by pressure wave created by the vehicle creating a [...]

How fast will I need to go to break the sound barrier ?

I want to hear a good sonic boom that will break glass .
sound travels at aprox. 750 miles per hour or 1100 feet per second. so thats how fast you must travel. but it depends on your proximity to the object that is breaking the sound barrier , for its ability to break glass

A commercial jet can break the sound barrier?

Author: admin Category: 5

For example a A-320, 767 or maybe a Jumbo.
Not normally, or at least not since the Concorde and TU-144 went out of service.
However, not many people remember that the first supersonic jet airliner was actually a Douglas DC-8. Granted, the aircraft was designed to fly at high-subsonic speeds, and could only break the speed of [...]

Does a pilot that breaks the sound barrier hear the sonic boom?

Author: admin Category: 5

No, a sonic boom is actually a very rapid change in ir pressure that travels in a cone shaped wave. This is why we call it a shockwave. At any point on the aircraft during thr flight, the air pressure is more or less unchanging. At least, it doesn’t change rapidly enough for the pilot [...]

who was the first aussie to break the sound barrier in an aircraft?

Author: admin Category: 5

In 1955 , 75 Sqd was reformed in Queensland and took deliver of the F-86 Sabre
The Sabre was capable of Mach 1.1 in a shallow dive.
Don’t know who was first credited with pushing thru first.
Some Aussie pilots also flew F86’s in the Korean conflict and used the earlier F-86 model with less powerful GE engine. [...]

what happens when the sound barrier is broken?

Author: admin Category: 5

i know there’s a sonic boom, and i realize i sound like a dumb blonde, but i can’t find anything explaining what exactly happens. help?
thanks yall
It’s related to something called a shock wave.
http://en.wikipedia.org/wiki/Shock_wave
The basic principle is that when something travels faster than the speed of sound in a particular medium, it generates shock [...]

Aircraft Breaking The Sound Barrier ~ Pink Floyd ~ One Of These Days

Author: admin Category: 5

In aerodynamics, the sound barrier usually refers to the point at which an aircraft moves from transonic to supersonic speed. The term came into use during World War II when a number of aircraft started to encounter the effects of compressibility, a grab-bag of unrelated aerodynamic effects. The term fell out of use in the [...]

What is the mathematical genius in passing the sound barrier?

Author: admin Category: 5

Websites or anything you know would be awesome. Just trying get some more information for a school paper.

Look for anything on Transonic aerodynamics.
