DE1578006C - Tube for flight stabilized missiles - Google Patents

Description

Pipe parts 2 and 3 matched to one another in terms of length 4 so that the guide surface 8 b is not completely covered by the sleeve 4, so that the grooves 10 can emerge in openings 11 to the outside. Any dirt on the connecting surfaces is pushed into the grooves 10 when the pipe parts are screwed together, from which the dirt can be blown out. The groove 10 expediently ends in a gently rising manner at 10 α. The grooves also serve the purpose of recognizing whether the end faces 9 α and 9 b are not screwed tightly against one another. With the continuous longitudinal grooves, the gases are discharged freely and the source of the error is recognized. In the absence of the longitudinal grooves 10, the powder gases escaping can cause welds on the guide surfaces or the thread. The blind holes 14 and 15, which are arranged distributed around the circumference, are used for the engagement of hook-shaped keys.
