2.  Description
A.  PW2000 Series Basic Engine
(1)  
The PW2000 series engine is a two-spool, axial flow, high bypass ratio turbofan. A two-stage high pressure turbine drives the 12-stage high pressure compressor. A five-stage low pressure turbine drives the fan and four-stage low pressure compressor. The accessory drive system extracts energy from the high pressure high-speed rotor to drive engine accessories and engine mounted airplane accessories.

(2)
Accessory items pertaining to engine operation such as fuel control unit, fuel pump, oil tank, oil fuel filters, oil pump, and other necessary equipment are supplied and installed by Pratt & Whitney Aircraft. Installation procedures for these items are contained in the Pratt & Whitney PW2000 Series Engine Manual.
