Title: Sonic booms
Post by: JunkyII on July 01, 2009, 02:27:17 AM: Saw this picture and I thinks its probably the best of a jet breaking the sound barrier Ive seen

article says he was breaking sound barrier i believe :salute

Very well could have been, transonic is mach 0.8 - 1.2. The vapor cone you see there though is from the Prandtl–Glauert singularity. The vapor cone, regardless, has been seen as breaking sound barrier for some reason, when the vapor cone will appear mach 0.2 before breaking the sound barrier.

Just got off my lazy bum and researched it. Here's the wiki on it...

Post by: RufusLeaking on July 01, 2009, 08:43:19 AM: The MD-11 shows water vapor forming in the area of low pressure on top of the wing under high humidity conditions.

There will be local shock waves forming on a plane in the transonic regime. A shock wave is a sudden change in pressure. This is what appears to be happening in the F-22 photo.

The term "breaking the sound barrier" is out dated. Airflow around an airplane varies with geometry. The discussion needs to be around Mach numbers, air pressure and humidity.

Can I but them from an Amway salesman?

Cool pic, Junky. Hope you are enjoying the Kim-Chi :aok

Title: Re: Sonic booms
Post by: moot on July 01, 2009, 12:04:13 PM: I've got one of those but zoomed in close and clear enough to see the shockwaves in the air itself, without any humidity. Can't find it though.

Ok so the last one it's not busting the mach, but it's still a sexy picture of pure power aircraft porn :x
