AVB-E nose and tail bomb fuze, Russia

[microplastic]

cutaway model of a russian AVB-E all ways acting fuze in armed condition. The fuze is electrically activated and can be used as nose or tail fuze. The fuze has a lenght of 155mm and a diameter of 60mm (top).

When the bomb is dropped , an electrical charge from the aircraft fires the electrical arming squib, which in ignites a pyrotechnic delay. The delay when burnt through, ignites a small propelling charge, which in pushes the arming plunger into the arming plunger housing. The spring is now free to reassert itself, pushing the arming rod, Firing pin housing and firing pin upwards. The firing cap is placed in line and locked, the fuze is armed.

am excited to see it, if i could cut the fuze once again, i would cut the fireing pin housing by 90 degrees off to see the slider in a better way...

As I cut two fuzes I had the luxury of executing one fuze in safe position (left), and the other one as armed (right).
I think the way you descided to cut it is perfect, I only made a minor addition in cutting the cup with the double pyrotechnic delay.
