Thanks.
I was under the impression that the V. Valiant was the first ‘all electric’ aircraft. Did not know the Victor had similar architecture. I think at that time in the British industry, the argument of DC vs. AC for large aircraft was still raging in the engineering community. The AC 400HZ approached was seen as ‘American influence’. The Valiant I think had a very complex high voltage (112V) main DC power, 96VDC electric engine starters, carbon-pile voltage regulators, slue of rotary inverters, converters, a ton of batteries, etc. To think that all these ancient brush type technology machines actually worked quite acceptably in the strategic bomber high altitude environment is amazing to me. The Victor and Vulcan went with the ‘latest’ American CSD/AC alternator approach. I think the Vulcan had the American Westinghouse 40kVA brushless AC generators built under license by English Electric, mounted on the license built Sundstrand CSD. Not sure what type of AC alternators are on the Victor.

Thanks VictorSim. It is interesting that the B.1s didn’t have these twin RATs, if I understand correctly. Must have been incorporated into the B.2s based on some operational experience with the B.1s??
What is the significance to being nuclear bomber , as opposed to otherwise in relation to the RATs?

Very interested to learn more about the electric system. This aircraft was basically all-electric. Today, everybody is talking about all-electric/more-electric aircraft (Boeing 787). Vickers did it in the 1950’s… Any information about the 112V generators, ratings, maintenance, experiences, starters, rotary inverters, converters, etc. Some of the actuation systems must have required tremendous amount of power (landing gear?) . What was used for emergency power (RAT, batteries, etc.) Quite an amazing decision back then to go all electric for such a critical platform.
