Can somone identify this?

This is one of the many things I received when my grandfather passed. Some I know what they are some I do not. This falls under the I do not category. I am hoping someone can give an educated guess on what it might be.

The whole thing comes apart. Its grooved and notched so everything fits very tightly. It has a steel shaft going half way through to the lower piece. Inside the lower piece are 4 small steel rings with holes in them.

Just so you have a little insight on where the item came from. My grandfather worked for the NRL for 30+ years different fields including, fracture mechanics, hypervelocity research, rocket development and in the space systems division. Hope this info helps.

can you take sharper pictures and give me more background?

Complete WAG here but did you look into Air to Surface fusing devices? With the description and pics it looks like it could be an impact fuse for a missile or bomb.

@Habu That is all the background I know really. He never really talked much about anything he did. The whole thing is made out of some sort of plastic. Its very hard. I can hit it with a hammer and nary a scratch. Sorry I cant take a better picture, I dont have a digital camera. All I have is the less than stellar cell phone cam.

@Zaphod That is the best WAG I have ever heard on this. It does make sense
as he did that type of research. Also I have another one almost identical to this one only about a quarter of the size. Ill have to start searching photos on the net and see if I can find something similar.

The work in hypervelocity research is a clue.

It looks like one of the early test sabot and projectile of the type that is used in hypervelocity research. they are called Long-rod projectiles.

They are also called APFSDS projectiles by the military/

Looks like a Cap gun of some sort, like Zaphod said, or rather a cap bomb.

it looks like a sabot for which it is fired out the end of a weapon aound the true projectile, then separates fron the projectile. this increases the initial velocity of the projectile

called a pusher member

You found my Nuclear powered Coffee Grinder!!!

Nice item though, and your Grandfather sounds like he had a very interesting life


Sorry about the loss btw.

Thats funny Agent. He was a very interesting guy to say the least. When he did tell stories they were always great. Thanks

It seems to be a launch port for a small bomb or explosive

it a valve of some sort

it has a income nozzle and grid inside are for distributing pressure of gas or liquid evenly inside of the valve

it also has 4 output nozzles

hope it helps

cheers
