Description

Each burner cup of the V2 rocket engine injector system has forty-four brass inserts, but each cup also has twenty-four 2mm diameter plain holes, 30 deg apart, drilled into the cup's central wall. To mimic this for testing purposes, we created a brass insert that has a base with just a 2mm central hole. The base is sized to be consistent with the 4 to 5mm cup wall. V2RH image

This month’s question

Can you help us identify the object below?

Mystery object
This part has a helicoid or screw shape, it seems that it might have been designed to screw into a pipe of some kind. But do you know what it is, and what it did? If you do, click on it and tell us.
