Aircraft Pumps and motors
I understand in the hydraulics system there are many different pumps and hydraulic motors in the system. May I ask what purpose each type serves and where are they mounted on the aircraft.
Some of the item i really want to find out about
AC motor pump
DC motor pump
Hydraulic driven motors
Are there any others?
Is there a general rule where such items are mounted on the aircraft?
ie For the B757 the Engine driven pump is supported by a AC motor pump, so is this AC motor mounted together with the engine driven inside the engine? And what about the Ac motor pumps that support the centre hydraulics system, where are they mounted?
