German bombs with a Soviet fuzes
- Thread starter mr_ango17
- Start date
We have seen a czech 15cm shell converted to an aerial bomb by cutting the tip of the SKHZR and replaced with an AM-A. No wonder it didn't exploded, since the original booster safety hadn't armed due to the lack of high acceleration. Fitting the SD and SC-50 bombs with AV-1 was a general practice though.
Hello,
Could you post diagrams and pictures of AV-1F, I don't know this fuze.
Thank you.
Regards
Hi there.
Here is the rough translation of the text:
„Fuze AV-1F
During the Great Patriotic War Soviet forces captured large quantities of bombs with side fuze well to be used with electric fuzes. The use of German fuzes asked for special electrical wiring for charging, not practical in battlefield environment. The German fuzes were also unreliable, bombs were often duds.
Soviet, more reliable, fuzes were considered to be used in these bombs. Soviet army had a fuze AV-1 that reliably worked on side impact if the arming vane was unscrewed. The vane was not ment to be used in the side well because side wind did not unscrew it. It was nescessary to design a vane which would unscrew by the wind coming from the side.
Engineer Frolov manufactured such a vane for the AV-1 fuze (pic 54) with half cylinder blades which reliably worked in the side well of the bomb. To distinguish the bomb from the AV-1 fuze the fuzes with Frolovs vane got the designation AV-1F.
The only difference between the AV-1 and AV-F is the shape of the arming vane blades. Pic 55 shows the AV-1F which operation is the same as the AV-1.
Fuze AV-1M
The fuze AV-1F solved the problem of using German trophy bombs by the Soviet air force during the Great Patriotic War. But the use of HE/frag or HE bombs asked for instantaneous fuze. The AV-1F had a delay of 22 seconds. It was necessary to change the fuze for instant action. For this the delay element and sleeve were removed from the AV-1F The new fuze got the designation AV-1M. In other respect there is no difference between AV-1F and AV-1M. Pic 56 shows the internal construction of the AV-1M.
Because the AV-1F and AV-1M are similar in appearance the AV-1 M has red band on the head of the fuze and on the body of the fuze designation for AV-1M.”
It is to say that the fuzes were found mostly in 50kg SC bombs, once in an incendiary bomb. There are at least 3 different ways to fix the fuze in the fuze well.

My friend from the Crimea took these photos.
The original fuze was lost. For photos, it replaced it with APUV.
Not exactly about combination German bomb+Soviet fuze+American airplane, but also could be interesting.
In 1942 printed special instruction for using German HE bombs on Soviet airplanes. Unfortunatly I know only instruction and where I found it in library - it "lost"
