And this is done so that the flyer plate does not impact the hull roof or glacis ? One big downside if true is that only a small proportion of the turret is now covered by ERA. Surely it would be best to use some moderately thick cover plate (ahead of some air gap) to contain the flyer plate and also protect the ERA and the non ERA covered turret section a little.

KV7 Posted June 17 Share Posted June 17 4 hours ago, Harkonnen said: What is shown on the picture? It is just my example of how it could be done. Here blue is medium hardness steel, green is elastomer, purple is NERA "flyer plate" of unspecified material. Front NERA element can be unbolted to access ERA canisters. But this is just a result of two minutes of thought, do not attach any significance to any details. Link to comment Share on other sites More sharing options...

Przezdzieblo Posted June 19 Share Posted June 19 Not so. This part of AD0048311 refers to earlier US research, based on WWII experiments with HCR. See Eichelberger's patent US3324768. Changing mastic binder to cast steel was another step which did not go well. Link to comment Share on other sites More sharing options...

Another went to the US. Link to comment Share on other sites More sharing options...

Which ignition type is the primary on a T-72, compressed air or electrical? Edited July 4 by Bichri001 Link to comment Share on other sites More sharing options...

Stefan Kotsch Posted July 4 Share Posted July 4 Yes, compressed air was already standard on the t-55 Link to comment Share on other sites More sharing options...
bojan Posted July 4 Share Posted July 4 That did come with T-55 right, on T-54 it was just a backup? Link to comment Share on other sites More sharing options...
Stefan Kotsch Posted July 5 Share Posted July 5 My manual for the T-54 and T-54A states that there was an option for starting the engine with compressed air. But there was no compressor. When the two compressed air bottles were empty, they had to be filled from the outside. That's why electric start was the main method. I don't have a manual for the T-54B. But if the T-54 manual from the 1969 edition does not describe a compressor, there probably won't be one in the T-54B. Link to comment Share on other sites More sharing options...
Interlinked Posted July 5 Share Posted July 5 (edited) The air compressor was a major new feature of the T-55 and its new gearbox, IIRC. Edited July 5 by Interlinked Link to comment Share on other sites More sharing options...

Отечественные бронированные машины 1945-1965 mentions the compressor first with the T-55. On the other hand, I have a manual of the Su-122 assault gun from 1957, it definitely mentions the AK-150V compressor. The 1958 manual supplement for T-54B doesnt hovewer...
