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

Volts- 120

KVA- 8

PH- 1

RPM 3800-10000

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.

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.

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.
