- Original Message - From: wilton strickland [EMAIL PROTECTED] To: [EMAIL PROTECTED] Sent: Wednesday, January 18, 2006 10:38 PM Subject: OT - Genset - MD-3 Before I was commissioned in '60, I was a maintenance crew chief on B-47s. I operated many MD-3s to provide power to the aircraft sitting on the ramp. During nearly 14 yrs flying B-52s, I also saw hundreds of MD-3s providing ground power to B-52s. I'm sure they supplied ground power to many other types of aircraft, too. Air Force must have had thousands of them. Wilton, LtCol, USAF, Ret.

Output = 28VDC, 60Hz 120/240AC 400Hz voltage I don't remember. Units were abt 4 1/2 ft tall, 5 1/2 ft long, 5 ft wide. 4 wheels - 2 in back, 2 in frnt in middle betwn base of tongue/tow bar. Towed to site on ramp; One could hold end of tow bar and work elec switch on the bar to reposition the unit on ramp. Frnt wheels were elec driven. Wilton

So my real question is whether or not the 60 Hz machine is synchronous or induction. Induction machines are much harder to turn into generators. And of course the presence of extra shaft length will be crucial as well. The 60 Hz machine is 220/440, so using it as a 120/240 generator will be interesting as well. Jim, The 125 KVA ones I had in the data center were induction start and transferred to syncronous run. Better ride through. Made by GE and some big German firm.
