1. INTRODUCTION
The aircraft is equipped with two General Electric CF34--3A1 high bypass ratio turbofan
engines which have a normal take-off thrust rating of 8,729 pounds flat rated at 21_C (70_F).
In the event of an engine failure during takeoff, an automatic power reserve (APR) system,
will increase the thrust on the remaining engine to 9,220 pounds.
The aircraft is equipped with two General Electric CF34--3B1 high bypass ratio turbofan
engines which have a normal take-off thrust rating of 8,729 pounds flat rated at 30_C (86_F).
In the event of an engine failure during takeoff, an automatic power reserve (APR) system,
will increase the thrust on the remaining engine to 9,220 pounds.<0005>
The engine is a dual rotor assembly consisting of a fan rotor (N1) and a compressor rotor
(N2). The N1 rotor consists of a single-stage fan connected through a shaft to a 4-stage low
pressure turbine. The N2 rotor is a 14-stage axial flow compressor connected through a
shaft to a 2-stage high pressure turbine.
For normal engine function, intake airflow is accelerated through the single-stage N1 fan and
is divided into two airflow paths:
S Bypass air -- Air that is ducted around the engine to produce approximately 85% of the
engine thrust. On landing, thrust reversers are used to direct the bypass air forward to
assist in braking.
S Core air -- Air that enters the engine core section is compressed, mixed with fuel and
