    Subject: Westinghouse Alternator B-52?
    --> AeroElectric-List message posted by: "Scott Auchinleck, Emergi-Tech" <scott@emergi-tech.qc.ca> Hello, I have recently acquired a Westinghouse alternator (possibly from a B-52?). The specs are below. Does anyone have any information on this unit (parts diag, service manual, etc). Was it mean to be run with a regulator, or at a constant speed= constant voltage setup? I plan to use it as part of a generator project, so I'm wondering how to set it up (since I don't own a B-52....) Thanks, Scott AF SPEC- 32530=D MFR'S SERIAL NO. AW-131 Volts- 120 KVA- 8 PH- 1 RPM 3800-10000 MFR'S PART NO.- A-24-A9370 Scott Auchinleck

    --> AeroElectric-List message posted by: Denis Walsh <denis.walsh@comcast.net> Can't help with the machine you have, however based on a lot of walk around inspections, I doubt if you have a B-52 alternator. the earliest models had 600 KVA brutes with sunstrand drives and were bleed air driven. They were rather large. There were four of them in the wheel well areas. Later models have engine driven units and I do not know what they were however surely they were even bigger. They were also 205 volts and 400 hertz. Of course my memory is being stretched a bit since I left that business in 1968.

    --> AeroElectric-List message posted by: "Robert L. Nuckolls, III" <nuckollsr@cox.net> Dennis, Your recollection echos my own. I worked on B-52s at Boeing (my first 'real' job out of high school). I was in electronics and didn't have much interface with the power distribution guys but I do recall seeing the hardware and hearing something of its capabilities in classes I attended at Boeing. I agree that unit Scott has is for a much smaller application. Further, 120v, single phase systems are exceedingly rare in aircraft. The only one's I've seen were produced from DC by solid state inverters, not from rotating machines. I suspect his generator was used in some non-aircraft specialty application.

    --> AeroElectric-List message posted by: "Richard Sipp" <rsipp@earthlink.net> It was certainly a long time ago in a place far away so I don't remember much. I do recall significant differences in the early model Buffs electrical systems and the later models. In the early versions each alternator had to be adjusted in frequency until it matched the buss (I guess) and when you got it close enough it could be added to the buss system with the others. I am not sure if they had constant speed drives or not. If I remember correctly the voltage took care of itself but the frequency was manually controlled and very touchy. One dark and stormy night over the Pacific, the whole airplane went black. The alternator control panel looked like a game of pin ball wizard with flashing lights all over the place. I picked one alternator at time and tried to get them back on and of course the rest of the crew was yelling at me to turn the lights back on.

    Subject: fuse questionis
    --> AeroElectric-List message posted by: sarg314 <sarg314@comcast.net> Bob: I note that Z-11 and others show a 7 amp fuse on the alternate feed line to the Endurance bus. The other feed, through the diode, is not fused, so why is this fuse there? Is it because that feed has a switch which provides a possible failure mode that could smoke the wire? Also, relating to selecting fuses in general, am I correct that the "10 deg C rise current" column in table 8-3 may be used as a guide to the maximum fuse rating to use for the various wire sizes? Thanks, -- Tom S. RV-6A
