AVU-ET bomb fuze, USSR

[Mrfuze]

Hello together,
I want to shear some images of a cutaway of mine, which is in the MTRC reference collection. It is the AVU-ET impact bomb fuze, used by the Russians from the 70's to current times. The fuze can be used as a nose fuze, a tail fuze or as a transverse fuze. It incorporates an all-ways action impact feature and a dual firing mechanism, one for the long delay circuit (10-14sec) and the other for the non-delay/short (0.02-0.04sec) or medium (0.06-0.09sec) delay circuit. The fuze also incorporates an electrically initiated pyrotechnical arming/safety device. The fuze was used in OFAB 100/120; 250/270; FAB-500M, FAB-500Sh; ZB-500 (inc.) & others.
Enjoy the images!

I've also wondered about these, thanks for the post! BTW: The umbilical for the initiator, how long was this? Have seen some that appear to be over 12", this one obviously not.

This one was a shorter version for display purposes, I believe.

Avu-et

yes, I shortened the cable in order to see all the internal parts so that I don't had to wrap the cable around the fuze body.
All fuzes I saw have had the same length of arming cable.
