I am looking for the Russian manual for the AVU Bomb fuze. I have the AVU-ET, but need the information on the AVU particularly the internal functioning. I would also like to see how the Russians discus how it works.

Thanks for the help,

Joe
 
AFAIK, members of the family are AVU-E, AVU-ET, AVU-ETM. I've found AVU in the GRAU list, but no details.

However i'm not Russian i might help with its function. If you have any question feel free to ask me even in PM
 
Hi Joe,
as far as I know, the AVU should have the same internal construction as the AVU-ET, but instead of the electric ignition of the pyrotechnic arming system of the latter, it has a mechanical ignition. This is for older aircraft models that do not contain the electrical arming system. So, also the bodies are identical the AVU has that "arming harness ???" sunk and screwed into the side of its body,(Excuse me, but I still have problems with the right english name for this item.) which seems to be the standard arming set up for all older models before adaption of the electrical arming system.
Bellifortis.
 
That's what I thought. I wanted to see if their manual had anything else to add. Plus the Russian manuals just fascinate me.

Sorry no manual,
but here a picture of the models AVU, AVU-E, AVU-ET and AVU-ETM.
I think I posted it before somewhere.

So, AVU have only mechanical ignition, AVU ETM have electrical and mechanical ignition, AVU-E an ET have only electrical ignition but is there an other differences between them?
 
AVU-E and AVU-ET are mechanically the same. The T variant is more temparature proof and there are minor differencies in arming and delay times. (the "P" setting is called "Sh" on the later)
 
Hi All
A regulation for AVU-E was issued in the Czechoslovak Army (Air Force) , dated 1966 (1967).
No separate regulation for AVU was issued.
Maybe it was part of something ....
If (and I don't know) the AVU bomb fuse was introduced in the Czechoslovak Air Force, it was before 1967.
------------
A question for other colleagues from the former Warsaw Pact countries, when was the regulation for AVU, AVU-E issued in your country.i.e. Poland, Romania, Hungary, Yugoslavia (?)
Akon
Czechoslovak Air Force : served Su-7 >1963 ( Su-7BM, Su-7BKL, Su-7U )
Su-17 >1984 (Su-22M-4 , Su-22UM-3 )
Su-25 >1988 (Su-25K , Su -25 UBK)
