@MrMKH2010 Seems to me that was just a generator, not a full on APU. Probably just provides low voltage for the starter motors, not the rest of the aircraft. The generators we used WERE massive (bout 4,000 lbs if I remember right), but they powered all systems on the plane.
@drmuelr The B-17 generators were type P-1 24 Volt DC 200 Ampere. They were not massive, pretty small compared to a jet engine AC Generator. The B-17 R-1820-97 engine only weighs about 1200 lbs. The B-17 internal APU, located in the aft fuselage, used for electrical power on the ground, is only about the size of a old lawn mower engine.
@MrMKH2010 The external APU you seen on the B-1s the size of a truck, were probably external A/C units used to cool the electronics on the ground. External power unit used by the B-1's A/M32A-86 called "Hobarts" are about the size of a pick up truck.
Those guys must have spent half of WW II just getting the damn engines started. LOL !
