How do bullets fly? (http://www.nennstiel-ruprecht.de/bullfly/index.htm#Contents)

Quote:

A quite simple experimental photographic technique which enables the visualization of the flow of air in the vicinity of a moving body produces a picture called a "shadowgraph".

This technique requires a short duration flash of light, which must originate from a point. As shown in the figure , not even a photographic lens is required. The shadowgraph of the bullet, passing at very close distance in front of a film or photographic plate, visualizes the pressure differences of the flowfield particularly well.

The pictures shown in the three following figures were taken by applying this simple but effective technique.

A .308 Winchester (7.62 x 51 Nato) FMJ bullet traveling at approximately 2800 ft/s (850 m/s). Note the change in flow type from laminar to turbulent at the bullet´s cannelure.

A cal. .32 ACP (7.65 mm Browning) pistol bullet, moving at a speed considerably below the speed of sound. Only turbulences (the wake) can be observed behind the bullet´s base.

Wow, that is so cool! Kinda looks like slow mo shooting from The Matrix. ;)

Very neat.
Not to hijack the thread, but does anyone know where you can fiind pics of bullets penetrating various inanimate objects like apples, oranges, etc. I had the web address but lost it. Some really neat effects.

You might find some of the photos you're looking for at the National Geographic web site. The man you want to search for is "Doc Edgarton".
Geographic did a nice story about his technique several years ago...I'm sure you'll find some of his photos still available.

Fascinating pics Sven ... thx.

I do have these three pics to hand ... re high speed shots ... enjoy ....

Hardtarget - You're thinking of Harold Edgerton. He is one of the acknowledged pioneers of high speed photography. I was fortunate and honored to be able to chat with him at the Nat. Geo. photo labs in the '60's. Fascinating gentleman. He's renowned for his high speed photography, but he is also greatly responsible for refining the ultra-precise timing technology that is required for nuclear devices.

You mean the cover of the first Bulletboys CD?
